Clinical Considerations Disease-associated maternal and/or embryo/fetal risk There is a risk to the mother from untreated schizophrenia, including increased risk of relapse, hospitalization, and suicide. Schizophrenia is associated with increased adverse perinatal outcomes, including preterm birth. It is not known if this is a direct result of the illness or other comorbid factors. Fetal/Neonatal adverse reactions Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder have been reported in neonates who have been exposed to antipsychotic drugs, including Clozapine ODT, during the third trimester of pregnancy. These symptoms have varied in severity. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. Data Animal Data In embryofetal developmental studies, clozapine had no effects on maternal parameters, litter sizes, or fetal parameters when administered orally to pregnant rats and rabbits during the period of organogenesis at doses up to 0.4 and 0.9 times, respectively, the MRHD of 900 mg/day on a mg/m 2 body surface area basis. In peri/postnatal developmental studies, pregnant female rats were administered clozapine over the last third of pregnancy and until day 21 postpartum. Observations were made on fetuses at birth and during the postnatal period; the offspring were allowed to reach sexual maturity and mated. Clozapine caused a decrease in maternal body weight but had no effects on litter size or body weights of either F1 or F2 generations at doses up to 0.4 times the MRHD of 900 mg/day on a mg/m 2 body surface area basis."],"overdosage":["10 OVERDOSAGE 10.1 Overdosage Experience The most commonly reported signs and symptoms associated with Clozapine ODT overdose are: sedation, delirium, coma, tachycardia, hypotension, respiratory depression or failure; and hypersalivation.

Orthostatic Hypotension, Bradycardia, Syncope Orthostatic hypotension, bradycardia, syncope, and cardiac arrest have occurred with clozapine treatment. The risk is highest during the initial titration period, particularly with rapid dose escalation. These reactions can occur with the first dose, with doses as low as 12.5 mg per day, or when restarting patients who have had even a brief interruption in treatment with Clozapine ODT. Initiate treatment at 12.5 mg once or twice daily; titrate slowly; and use divided dosages to minimize risk. Use Clozapine ODT cautiously in patients with cardiovascular or cerebrovascular disease or conditions predisposing to hypotension (e.g., dehydration, use of antihypertensive medications) [see Dosage and Administration (2.3 and 2.6) , Warnings and Precautions (5.2) ] . Seizures Seizures have occurred with clozapine treatment. The risk is dose-related. Initiate treatment at 12.5 mg, titrate gradually, and use divided dosing. Use caution when administering Clozapine ODT to patients with a history of seizures or other predisposing risk factors for seizure (CNS pathology, medications that lower the seizure threshold, alcohol abuse). Caution patients about engaging in any activity where sudden loss of consciousness could cause serious risk to themselves or others [see Dosage and Administration (2.3) , Warnings and Precautions (5.4) ] . Myocarditis, Pericarditis, Cardiomyopathy and Mitral Valve Incompetence Fatal myocarditis and cardiomyopathy have occurred with clozapine treatment. Discontinue Clozapine ODT and obtain a cardiac evaluation upon suspicion of these reactions. Generally, patients with clozapine-related myocarditis or cardiomyopathy should not be rechallenged with Clozapine ODT. Consider the possibility of myocarditis, pericarditis, or cardiomyopathy if chest pain, tachycardia, palpitations, dyspnea, fever, flu-like symptoms, hypotension, or ECG changes occur [see Warnings and Precautions (5.5) ] .

The antipsychotic trials must have been judged adequate; the antipsychotic dosages must have been equivalent to or greater than 1000 mg per day of chlorpromazine for a period of at least 6 weeks, each without significant reduction of symptoms. There must have been no period of good functioning within the preceding 5 years. Patients must have had a baseline score of at least 45 on the investigator-rated Brief Psychiatric Rating Scale (BPRS). On the 18-item BPRS, 1 indicates the absence of symptoms, and 7 indicates severe symptoms; the maximum potential total BPRS score is 126. At baseline, the mean BPRS score was 61. In addition, patients must have had a score of at least 4 on at least two of the following four individual BPRS items: conceptual disorganization, suspiciousness, hallucinatory behavior, and unusual thought content. Patients must have had a Clinical Global Impressions – Severity Scale score of at least 4 (moderately ill). In the prospective, lead-in phase of the trial, all patients (N = 305) initially received single-blind treatment with haloperidol (the mean dose was 61 mg per day) for 6 weeks. More than 80% of patients completed the 6-week trial. Patients with an inadequate response to haloperidol (n = 268) were randomized to double-blind treatment with clozapine (N = 126) or chlorpromazine (N = 142). The maximum daily clozapine dose was 900 mg; the mean daily dose was > 600 mg. The maximum daily chlorpromazine dose was 1800 mg; the mean daily dose was > 1200 mg. The primary endpoint was treatment response, predefined as a decrease in BPRS score of at least 20% and either (1) a CGI-S score of ≤ 3 (mildly ill), or (2) a BPRS score of ≤ 35, at the end of 6 weeks of treatment. Approximately 88% of patients from the clozapine and chlorpromazine groups completed the 6-week trial. At the end of six weeks, 30% of the clozapine group responded to treatment, and 4% of the chlorpromazine group responded to treatment. The difference was statistically significant (p < 0.001). The mean change in total BPRS score was -16 and -5 in the clozapine and chlorpromazine group, respectively; the mean change in the 4 key BPRS item scores was -5 and -2 in the clozapine and chlorpromazine group, respectively; and the mean change in CGI-S score was -1.2 and -0.4, in the clozapine and chlorpromazine group, respectively. These changes in the clozapine group were statistically significantly greater than in the chlorpromazine group (p < 0.001 in each analysis). 14.2 Recurrent Suicidal Behavior in Schizophrenia or Schizoaffective Disorder The effectiveness of clozapine in reducing the risk of recurrent suicidal behavior was assessed in the International Suicide Prevention Trial (InterSePT™, a trademark of Novartis Pharmaceuticals Corporation). This was a prospective, randomized, open-label, active-controlled, multicenter, international, parallel-group comparison of clozapine (Clozaril ® ) versus olanzapine (Zyprexa ® , a registered trademark of Eli Lilly and Company) in 956 patients with schizophrenia or schizoaffective disorder (DSM-IV) who were judged to be at risk for recurrent suicidal behavior. Only about one-fourth of these patients (27%) were considered resistant to standard antipsychotic drug treatment. To enter the trial, patients must have met one of the following criteria: They had attempted suicide within the three years prior to their baseline evaluation. They had been hospitalized to prevent a suicide attempt within the three years prior to their baseline evaluation. They demonstrated moderate-to-severe suicidal ideation with a depressive component within one week prior to their baseline evaluation. They demonstrated moderate-to-severe suicidal ideation accompanied by command hallucinations to do self-harm within one week prior to their baseline evaluation. Dosing regimens for each treatment group were determined by individual investigators and were individualized by patient. Dosing was flexible, with a dose range of 200 to 900 mg/day for clozapine and 5 to 20 mg/day for olanzapine. For the 956 patients who received clozapine or olanzapine in this study, there was extensive use of concomitant psychotropics: 84% with antipsychotics, 65% with anxiolytics, 53% with antidepressants, and 28% with mood stabilizers. There was significantly greater use of concomitant psychotropic medications among the patients in the olanzapine group. The primary efficacy measure was time to (1) a significant suicide attempt, including a completed suicide; (2) hospitalization due to imminent suicide risk, including increased level of surveillance for suicidality for patients already hospitalized; or (3) worsening of suicidality severity as demonstrated by “much worsening” or “very much worsening” from baseline in the Clinical Global Impression of Severity of Suicidality as assessed by the Blinded Psychiatrist (CGI-SS-BP) scale. A determination of whether or not a reported event met criterion 1 or 2 above was made by the Suicide Monitoring Board (SMB), a group of experts blinded to patient data. A total of 980 patients were randomized to the study and 956 received study medication. Sixty-two percent of the patients were diagnosed with schizophrenia, and the remainder (38%) were diagnosed with schizoaffective disorder. Only about one-fourth of the total patient population (27%) was identified as “treatment-resistant” at baseline. There were more males than females in the study (61% of all patients were male). The mean age of patients entering the study was 37 years of age (range: 18 to 69). Most patients were Caucasian (71%), 15% were Black, 1% were Asian, and 13% were classified as being of “other” races. Patients treated with clozapine had a statistically significant longer delay in the time to recurrent suicidal behavior in comparison with olanzapine. This result should be interpreted only as evidence of the effectiveness of clozapine in delaying time to recurrent suicidal behavior and not a demonstration of the superior efficacy of clozapine over olanzapine. The probability of experiencing (1) a significant suicide attempt, including a completed suicide, or (2) hospitalization because of imminent suicide risk, including increased level of surveillance for suicidality for patients already hospitalized, was lower for clozapine patients than for olanzapine patients at Week 104: clozapine 24% versus olanzapine 32%; 95% CI of the difference: 2%, 14% (Figure 1).

Clozapine causes little or no prolactin elevation. Clinical electroencephalogram (EEG) studies demonstrated that clozapine increases delta and theta activity and slows dominant alpha frequencies. Enhanced synchronization occurs. Sharp wave activity and spike and wave complexes may also develop. Patients have reported an intensification of dream activity during clozapine therapy. REM sleep was found to be increased to 85% of the total sleep time. In these patients, the onset of REM sleep occurred almost immediately after falling asleep."],"pharmacokinetics":["12.3 Pharmacokinetics Absorption In humans, Clozapine ODT (25 mg and 100 mg) is equally bioavailable relative to a clozapine oral solution. Clozapine ODT is bioequivalent to Clozaril ® (clozapine) tablets. Following a dosage of 100 mg twice daily, the average steady-state peak plasma concentration was 413 ng/mL (range: 132 to 854 ng/mL), occurring at the average of 2.3 hours (range: 1 to 6 hours) after dosing. The average minimum concentration at steady-state was 168 ng/mL (range: 45 to 574 ng/mL), after 100 mg b.i.d. dosing. A comparative bioequivalence/bioavailability study was conducted in 32 patients (with schizophrenia or schizoaffective disorder) comparing Clozapine ODT 200 mg to 2 × Clozapine ODT 100 mg (the approved reference product) under fasted conditions. The study also evaluated the effect of food and chewing on the pharmacokinetics of the 200 mg tablet. Under fasted conditions, the mean AUC ss and C min,ss of clozapine for the 200 mg oral disintegrating tablets were equivalent to those of the 2 x 100 mg tablets. The mean C max,ss of clozapine for Clozapine ODT 200 mg was 85% that for 2 x 100 mg Clozapine ODT. This decrease in C max,ss for Clozapine ODT 200 mg is not clinically significant. For Clozapine ODT 200 mg, food significantly increased the C min,ss of clozapine by 21%. However, this increase is not clinically significant. The mean AUC ss and C max,ss of clozapine under fed conditions were equivalent to those under fasted conditions. Food delayed clozapine absorption by 1.5 hours, from a median T max of 2.5 hours under fasted conditions to 4 hours under fed conditions. The mean C max,ss of clozapine under chewed conditions for Clozapine ODT 200 mg was about 86% that for 2 x 100 mg Clozapine ODT under non-chewed conditions, while the AUC ss and C min,ss values were similar between the chewed and non-chewed conditions. In a food-effect study, a single dose of Clozapine ODT 12.5 mg was administered to healthy volunteers under fasting conditions and after a high-fat meal. When Clozapine ODT was administered after a high-fat meal, the C max of both clozapine and its active metabolite, desmethylclozapine, were decreased by approximately 20%, compared to administration under fasting conditions, while the AUC values were unchanged. This decrease in C max is not clinically significant. Therefore, Clozapine ODT can be taken without regard to meals. Distribution Clozapine is approximately 97% bound to serum proteins. The interaction between clozapine and other highly protein-bound drugs has not been fully evaluated but may be important [see Drug Interactions (7) ] . Metabolism and Excretion Clozapine is almost completely metabolized prior to excretion, and only trace amounts of unchanged drug are detected in the urine and feces. Clozapine is a substrate for many cytochrome P450 isozymes, in particular CYP1A2, CYP2D6, and CYP3A4. Approximately 50% of the administered dose is excreted in the urine and 30% in the feces. The demethylated, hydroxylated, and N -oxide derivatives are components in both urine and feces. Pharmacological testing has shown the desmethyl metabolite (norclozapine) to have only limited activity, while the hydroxylated and N -oxide derivatives were inactive. The mean elimination half-life of clozapine after a single 75 mg dose was 8 hours (range: 4 to 12 hours), compared to a mean elimination half-life of 12 hours (range: 4 to 66 hours), after achieving steady-state with 100 mg twice daily dosing. A comparison of single-dose and multiple-dose administration of Clozapine ODT demonstrated that the elimination half-life increased significantly after multiple dosing relative to that after single-dose administration, suggesting the possibility of concentration-dependent pharmacokinetics. However, at steady-state, approximately dose-proportional changes with respect to AUC (area under the curve), peak, and minimum clozapine plasma concentrations were observed after administration of 37.5, 75, and 150 mg twice daily. Drug-Drug Interaction Studies Fluvoxamine: A pharmacokinetic study was conducted in 16 patients with schizophrenia who received clozapine under steady-state conditions. After coadministration of fluvoxamine for 14 days, mean trough concentrations of clozapine and its metabolites, N -desmethylclozapine and clozapine N -oxide, were elevated about three-fold compared to baseline steady-state concentrations. Paroxetine, Fluoxetine, and Sertraline: In a study of patients with schizophrenia (n = 14) who received clozapine under steady-state conditions, coadministration of paroxetine produced only minor changes in the levels of clozapine and its metabolites. However, other published reports describe modest elevations (less than two-fold) of clozapine and metabolite concentrations when clozapine was taken with paroxetine, fluoxetine, and sertraline. Specific Population Studies Renal or Hepatic Impairment: No specific pharmacokinetic studies were conducted to investigate the effects of renal or hepatic impairment on the pharmacokinetics of clozapine. Higher clozapine plasma concentrations are likely in patients with significant renal or hepatic impairment when given usual doses. CYP2D6 Poor Metabolizers: A subset (3% to 10%) of the population has reduced activity of CYP2D6 (CYP2D6 poor metabolizers).

Patients with Pneumonia and Other Inflammatory Conditions: Published case reports describe examples where pneumonia or other inflammatory conditions may increase clozapine concentrations.

( 2.7 , 7.1 ) Concomitant use of Strong CYP3A4 Inducers is not recommended. ( 2.7 , 7.1 ) Discontinuation of CYP1A2 or CYP3A4 Inducers: Consider reducing Clozapine ODT dose when CYP1A2 (e.g., tobacco smoke) or CYP3A4 inducers (e.g., carbamazepine) are discontinued. ( 2.7 , 7.1 ) Anticholinergic drugs: Concomitant use may increase the risk for anticholinergic toxicity. ( 5.7 , 5.15 , 7.1 ) 7.1 Potential for Other Drugs to Affect Clozapine ODT Clozapine is a substrate for many cytochrome P450 isozymes, in particular CYP1A2, CYP3A4, and CYP2D6. Use caution when administering Clozapine ODT concomitantly with drugs that are inducers or inhibitors of these enzymes. CYP1A2 Inhibitors Concomitant use of Clozapine ODT and CYP1A2 inhibitors can increase plasma levels of clozapine, potentially resulting in adverse reactions. Reduce the Clozapine ODT dose to one-third of the original dose when Clozapine ODT is coadministered with strong CYP1A2 inhibitors (e.g., fluvoxamine, ciprofloxacin, or enoxacin). The Clozapine ODT dose should be increased to the original dose when coadministration of strong CYP1A2 inhibitors is discontinued [see Dosage and Administration (2.7) , Clinical Pharmacology (12.3) ] . Moderate or weak CYP1A2 inhibitors include oral contraceptives and caffeine. Monitor patients closely when Clozapine ODT is coadministered with these inhibitors. Consider reducing the Clozapine ODT dosage if necessary [see Dosage and Administration (2.7) ] . CYP2D6 and CYP3A4 Inhibitors Concomitant treatment with Clozapine ODT and CYP2D6 or CYP3A4 inhibitors (e.g., cimetidine, escitalopram, erythromycin, paroxetine, bupropion, fluoxetine, quinidine, duloxetine, terbinafine, or sertraline) can increase clozapine levels and lead to adverse reactions [see Clinical Pharmacology (12.3) ] . Use caution and monitor patients closely when using such inhibitors. Consider reducing the Clozapine ODT dose [see Dosage and Administration (2.7) ] . CYP1A2 and CYP3A4 Inducers Concomitant treatment with drugs that induce CYP1A2 or CYP3A4 can decrease the plasma concentration of clozapine, resulting in decreased effectiveness of Clozapine ODT. Tobacco smoke is a moderate inducer of CYP1A2. Strong CYP3A4 inducers include carbamazepine, phenytoin, St. John’s wort, and rifampin. It may be necessary to increase the Clozapine ODT dose if used concomitantly with inducers of these enzymes. However, concomitant use of Clozapine ODT and strong CYP3A4 inducers is not recommended [see Dosage and Administration (2.7) ] . Consider reducing the Clozapine ODT dosage when discontinuing coadministered enzyme inducers, because discontinuation of inducers can result in increased clozapine plasma levels and an increased risk of adverse reactions [see Dosage and Administration (2.7) ] . Anticholinergic Drugs Concomitant treatment with Clozapine ODT and other drugs with anticholinergic activity (e.g., benztropine, cyclobenzaprine, diphenhydramine) can increase the risk for anticholinergic toxicity and severe gastrointestinal adverse reactions related to hypomotility. Avoid concomitant use of Clozapine ODT with anticholinergic drugs when possible [see Warnings and Precautions (5.7 , 5.15) ] . Drugs that Cause QT Interval Prolongation Use caution when administering concomitant medications that prolong the QT interval or inhibit the metabolism of clozapine. Drugs that cause QT prolongation include: specific antipsychotics (e.g., ziprasidone, iloperidone, chlorpromazine, thioridazine, mesoridazine, droperidol, and pimozide), specific antibiotics (e.g., erythromycin, gatifloxacin, moxifloxacin, sparfloxacin), Class 1A antiarrhythmics (e.g., quinidine, procainamide) or Class III antiarrhythmics (e.g., amiodarone, sotalol), and others (e.g., pentamidine, levomethadyl acetate, methadone, halofantrine, mefloquine, dolasetron mesylate, probucol or tacrolimus) [see Warnings and Precautions (5.9) ] . 7.2 Potential for Clozapine ODT to Affect Other Drugs Concomitant use of Clozapine ODT with other drugs metabolized by CYP2D6 can increase levels of these CYP2D6 substrates. Use caution when coadministering Clozapine ODT with other drugs that are metabolized by CYP2D6. It may be necessary to use lower doses of such drugs than usually prescribed. Such drugs include specific antidepressants, phenothiazines, carbamazepine, and Type 1C antiarrhythmics (e.g., propafenone, flecainide, and encainide)."],"mechanism_of_action":["12.1 Mechanism of Action The mechanism of action of clozapine is unknown.

However, it has been proposed that the therapeutic efficacy of Clozapine ODT in schizophrenia is mediated through antagonism of the dopamine type 2 (D 2 ) and the serotonin type 2A (5-HT 2A ) receptors. Clozapine also acts as an antagonist at adrenergic, cholinergic, histaminergic and other dopaminergic and serotonergic receptors. 12.2 Pharmacodynamics Clozapine demonstrated binding affinity to the following receptors: histamine H 1 (K i 1.1 nM), adrenergic α 1A (K i 1.6 nM), serotonin 5-HT 6 (K i 4 nM ) , serotonin 5-HT 2A (K i 5.4 nM), muscarinic M 1 (K i 6.2 nM), serotonin 5-HT 7 (K i 6.3 nM), serotonin 5-HT 2C (K i 9.4 nM), dopamine D 4 (K i 24 nM), adrenergic α 2A (K i 90 nM), serotonin 5-HT 3 (K i 95 nM), serotonin 5-HT 1A (K i 120 nM), dopamine D 2 (K i 160 nM), dopamine D 1 (K i 270 nM), dopamine D 5 (K i 454 nM), and dopamine D 3 (K i 555 nM). Clozapine causes little or no prolactin elevation. Clinical electroencephalogram (EEG) studies demonstrated that clozapine increases delta and theta activity and slows dominant alpha frequencies. Enhanced synchronization occurs. Sharp wave activity and spike and wave complexes may also develop. Patients have reported an intensification of dream activity during clozapine therapy. REM sleep was found to be increased to 85% of the total sleep time. In these patients, the onset of REM sleep occurred almost immediately after falling asleep. 12.3 Pharmacokinetics Absorption In humans, Clozapine ODT (25 mg and 100 mg) is equally bioavailable relative to a clozapine oral solution. Clozapine ODT is bioequivalent to Clozaril ® (clozapine) tablets. Following a dosage of 100 mg twice daily, the average steady-state peak plasma concentration was 413 ng/mL (range: 132 to 854 ng/mL), occurring at the average of 2.3 hours (range: 1 to 6 hours) after dosing. The average minimum concentration at steady-state was 168 ng/mL (range: 45 to 574 ng/mL), after 100 mg b.i.d. dosing. A comparative bioequivalence/bioavailability study was conducted in 32 patients (with schizophrenia or schizoaffective disorder) comparing Clozapine ODT 200 mg to 2 × Clozapine ODT 100 mg (the approved reference product) under fasted conditions. The study also evaluated the effect of food and chewing on the pharmacokinetics of the 200 mg tablet. Under fasted conditions, the mean AUC ss and C min,ss of clozapine for the 200 mg oral disintegrating tablets were equivalent to those of the 2 x 100 mg tablets. The mean C max,ss of clozapine for Clozapine ODT 200 mg was 85% that for 2 x 100 mg Clozapine ODT. This decrease in C max,ss for Clozapine ODT 200 mg is not clinically significant. For Clozapine ODT 200 mg, food significantly increased the C min,ss of clozapine by 21%. However, this increase is not clinically significant. The mean AUC ss and C max,ss of clozapine under fed conditions were equivalent to those under fasted conditions. Food delayed clozapine absorption by 1.5 hours, from a median T max of 2.5 hours under fasted conditions to 4 hours under fed conditions. The mean C max,ss of clozapine under chewed conditions for Clozapine ODT 200 mg was about 86% that for 2 x 100 mg Clozapine ODT under non-chewed conditions, while the AUC ss and C min,ss values were similar between the chewed and non-chewed conditions. In a food-effect study, a single dose of Clozapine ODT 12.5 mg was administered to healthy volunteers under fasting conditions and after a high-fat meal. When Clozapine ODT was administered after a high-fat meal, the C max of both clozapine and its active metabolite, desmethylclozapine, were decreased by approximately 20%, compared to administration under fasting conditions, while the AUC values were unchanged. This decrease in C max is not clinically significant. Therefore, Clozapine ODT can be taken without regard to meals. Distribution Clozapine is approximately 97% bound to serum proteins. The interaction between clozapine and other highly protein-bound drugs has not been fully evaluated but may be important [see Drug Interactions (7) ] . Metabolism and Excretion Clozapine is almost completely metabolized prior to excretion, and only trace amounts of unchanged drug are detected in the urine and feces. Clozapine is a substrate for many cytochrome P450 isozymes, in particular CYP1A2, CYP2D6, and CYP3A4. Approximately 50% of the administered dose is excreted in the urine and 30% in the feces. The demethylated, hydroxylated, and N -oxide derivatives are components in both urine and feces. Pharmacological testing has shown the desmethyl metabolite (norclozapine) to have only limited activity, while the hydroxylated and N -oxide derivatives were inactive. The mean elimination half-life of clozapine after a single 75 mg dose was 8 hours (range: 4 to 12 hours), compared to a mean elimination half-life of 12 hours (range: 4 to 66 hours), after achieving steady-state with 100 mg twice daily dosing. A comparison of single-dose and multiple-dose administration of Clozapine ODT demonstrated that the elimination half-life increased significantly after multiple dosing relative to that after single-dose administration, suggesting the possibility of concentration-dependent pharmacokinetics. However, at steady-state, approximately dose-proportional changes with respect to AUC (area under the curve), peak, and minimum clozapine plasma concentrations were observed after administration of 37.5, 75, and 150 mg twice daily. Drug-Drug Interaction Studies Fluvoxamine: A pharmacokinetic study was conducted in 16 patients with schizophrenia who received clozapine under steady-state conditions. After coadministration of fluvoxamine for 14 days, mean trough concentrations of clozapine and its metabolites, N -desmethylclozapine and clozapine N -oxide, were elevated about three-fold compared to baseline steady-state concentrations. Paroxetine, Fluoxetine, and Sertraline: In a study of patients with schizophrenia (n = 14) who received clozapine under steady-state conditions, coadministration of paroxetine produced only minor changes in the levels of clozapine and its metabolites. However, other published reports describe modest elevations (less than two-fold) of clozapine and metabolite concentrations when clozapine was taken with paroxetine, fluoxetine, and sertraline. Specific Population Studies Renal or Hepatic Impairment: No specific pharmacokinetic studies were conducted to investigate the effects of renal or hepatic impairment on the pharmacokinetics of clozapine. Higher clozapine plasma concentrations are likely in patients with significant renal or hepatic impairment when given usual doses. CYP2D6 Poor Metabolizers: A subset (3% to 10%) of the population has reduced activity of CYP2D6 (CYP2D6 poor metabolizers). These individuals may develop higher than expected plasma concentrations of clozapine when given usual doses. Patients with Pneumonia and Other Inflammatory Conditions: Published case reports describe examples where pneumonia or other inflammatory conditions may increase clozapine concentrations. The clinical significance, the impact of treatments to modulate this inflammation, and mechanism of this potential increase in clozapine concentrations have not been fully characterized but may involve reduced cytochrome P450 1A2 activity."],"indications_and_usage":["1 INDICATIONS AND USAGE Clozapine orally disintegrating tablets (Clozapine ODT) is an atypical antipsychotic indicated for: Treatment of severely ill patients with schizophrenia who fail to respond adequately to standard antipsychotic treatment. Because of the risks of severe neutropenia and of seizure associated with its use, Clozapine ODT should be used only in patients who have failed to respond adequately to standard antipsychotic treatment ( 1.1 ) Reducing the risk of recurrent suicidal behavior in patients with schizophrenia or schizoaffective disorder who are judged to be at chronic risk for re-experiencing suicidal behavior ( 1.2 ) 1.1 Treatment-resistant Schizophrenia Clozapine Orally Disintegrating Tablets (Clozapine ODT) are indicated for the treatment of severely ill patients with schizophrenia who fail to respond adequately to standard antipsychotic treatment. Because of the risks of severe neutropenia and of seizure associated with their use, Clozapine ODT should be used only in patients who have failed to respond adequately to standard antipsychotic treatment [see Warnings and Precautions (5.1 , 5.4) ]. The effectiveness of Clozapine ODT in treatment-resistant schizophrenia was demonstrated in a 6-week, randomized, double-blind, active-controlled study comparing Clozapine ODT and chlorpromazine in patients who had failed other antipsychotics [see Clinical Studies (14.1) ]. 1.2 Reduction in the Risk of Recurrent Suicidal Behavior in Schizophrenia or Schizoaffective Disorder Clozapine ODT is indicated for reducing the risk of recurrent suicidal behavior in patients with schizophrenia or schizoaffective disorder who are judged to be at chronic risk for re-experiencing suicidal behavior, based on history and recent clinical state. Suicidal behavior refers to actions by a patient that put him/herself at risk for death. The effectiveness of Clozapine ODT in reducing the risk of recurrent suicidal behavior was demonstrated over a two-year treatment period in the InterSePT™ trial [see Clinical Studies (14.2) ] ."],"warnings_and_cautions":["5 WARNINGS AND PRECAUTIONS Severe neutropenia: See ( 5.1 ) Gastrointestinal Hypomotility with Severe Complications: Severe gastrointestinal adverse reactions have occurred with the use of clozapine. If constipation is identified, close monitoring and prompt treatment is advised. ( 5.7 ) Eosinophilia: Assess for organ involvement (e.g., myocarditis, pancreatitis, hepatitis, colitis, nephritis). Discontinue if these occur. ( 5.8 ) QT Interval Prolongation: Can be fatal. Consider additional risk factors for prolonged QT interval (disorders and drugs). ( 5.9 ) Metabolic Changes: Atypical antipsychotic drugs have been associated with metabolic changes that may increase cardiovascular/cerebrovascular risk. These metabolic changes include ( 5.10 ): Hyperglycemia and Diabetes Mellitus: Monitor for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Monitor glucose regularly in patients with diabetes or at risk for diabetes. Dyslipidemia: Undesirable alterations in lipids have occurred in patients treated with atypical antipsychotics. Weight Gain: Significant weight gain has occurred. Monitor weight gain. Neuroleptic Malignant Syndrome (NMS): Immediately discontinue and monitor closely. Assess for co-morbid conditions. ( 5.11 ) Hepatotoxicity: Can be fatal. Monitor for hepatotoxicity. Discontinue treatment if hepatitis or transaminase elevations combined with other symptoms occur. ( 5.12 ) Fever: Evaluate for infection and for neutropenia, NMS. ( 5.13 ) Pulmonary Embolism (PE): Consider PE if respiratory distress, chest pain, or deep vein thrombosis occurs. ( 5.14 ) Anticholinergic Toxicity: When possible, avoid use with other anticholinergic drugs and use with caution in patients with a current diagnosis or prior history of constipation, urinary retention, clinically significant prostatic hypertrophy, or other conditions in which anticholinergic effects can lead to significant adverse reactions. ( 5.15 , 7.1 ) Interference with Cognitive and Motor Performance: Advise caution when operating machinery, including automobiles. ( 5.16 ) 5.1 Severe Neutropenia Clozapine has caused severe neutropenia (absolute neutrophil count (ANC) less than 500/µL) [see Adverse Reactions (6.1 , 6.2) ] and is associated with an increased risk of serious and potentially fatal infections. Severe neutropenia occurred in a small percentage of clozapine-treated patients. The risk of severe neutropenia appears greatest during the first 18 weeks of Clozapine ODT treatment. The mechanism by which Clozapine ODT causes neutropenia is unknown. Neutropenia is not dose-dependent. Consider a hematology consultation before initiating Clozapine ODT treatment or during treatment. ANC Monitoring and Dosage Modifications Prior to initiating Clozapine ODT treatment, obtain a baseline ANC. Clozapine ODT initiation is not recommended in patients with a baseline ANC less than 1500/µL. Throughout Clozapine ODT treatment, regularly monitor ANC. Table 1 provides recommendations for dosage modifications (dosage interruption and treatment discontinuation), based on ANC levels, during Clozapine ODT treatment and frequency of ANC monitoring [see Dosage and Administration (2.4) ] . ANC Monitoring and Dosage Modification in Patients with Benign Ethnic Neutropenia Patients with Benign Ethnic Neutropenia (BEN) (also known as Duffy-null associated neutrophil count) generally have lower baseline neutrophil counts but they are not at higher risk for developing infections, and they are not at increased risk for developing Clozapine ODT-induced neutropenia. For patients with documented BEN, obtain at least two baseline ANC levels prior to Clozapine ODT initiation. Clozapine ODT initiation is not recommended in patients with BEN with an ANC less than 1000/µL. There are different ANC dosage modification recommendations in Clozapine ODT-treated patients with BEN due to their lower baseline ANC levels. Table 2 provides recommendations on dosage modifications (dosage interruption and treatment discontinuation), based on ANC monitoring, during Clozapine ODT treatment in patients with BEN and recommended frequency of ANC testing [see Dosage and Administration (2.4) ] . Management of Clozapine ODT-Treated Patients Who Develop a Fever For patients who develop a fever during Clozapine ODT treatment: Interrupt Clozapine ODT in those who develop a temperature of 101.3 °F (38.5 °C) or greater and obtain an ANC level. If the ANC is less than 1000/µL in patients without BEN, initiate appropriate workup and treatment for infection. Refer to Table 1 or Table 2 for dosage modifications based on ANC monitoring [see Dosage and Administration (2.3) ] . In patients with fever and a normal neutrophil count, see Warnings and Precautions (5.11) for neuroleptic malignant syndrome and Warnings and Precautions (5.13) for fever. Restarting Clozapine ODT in Patients Who Recovered from Severe Neutropenia Generally, do not rechallenge patients with Clozapine ODT in those who experienced severe neutropenia. However, for some patients who had resolution of their Clozapine ODT-related severe neutropenia after stopping Clozapine ODT, the risk of schizophrenia exacerbation from not restarting Clozapine ODT treatment may be greater than the risk of neutropenia reoccurrence from restarting Clozapine ODT (e.g., patients who have no treatment options other than Clozapine ODT). Concomitant Use of Clozapine ODT with Other Drugs Known to Cause Neutropenia If Clozapine ODT is used concomitantly with another drug known to cause neutropenia, consider more frequently ANC monitoring than the recommendations provided in Tables 1 and 2. 5.2 Orthostatic Hypotension, Bradycardia, and Syncope Hypotension, bradycardia, syncope, and cardiac arrest have occurred with clozapine treatment. The risk is highest during the initial titration period, particularly with rapid dose-escalation. These reactions can occur with the first dose, at doses as low as 12.5 mg. These reactions can be fatal. The syndrome is consistent with neurally mediated reflex bradycardia (NMRB). Clozapine ODT treatment must begin at a maximum dose of 12.5 mg once daily or twice daily. The total daily dose can be increased in increments of 25 mg to 50 mg per day, if well-tolerated, to a target dose of 300 mg to 450 mg per day (administered in divided doses) by the end of 2 weeks. Subsequently, the dose can be increased weekly or twice weekly, in increments of up to 100 mg. The maximum Clozapine ODT dosage is 900 mg per day. Use cautious titration and a divided dosage schedule to minimize the risk of serious cardiovascular reactions [see Dosage and Administration (2.2) ] . Consider reducing the dose if hypotension occurs. When restarting Clozapine ODT in patients who have had even a brief interruption in treatment with Clozapine ODT, the dosage must be reduced. This is necessary to minimize the risk of hypotension, bradycardia, and syncope [see Dosage and Administration (2.6) ] . Use Clozapine ODT cautiously in patients with cardiovascular disease (history of myocardial infarction or ischemia, heart failure, or conduction abnormalities), cerebrovascular disease, and conditions which would predispose patients to hypotension (e.g., concomitant use of antihypertensives, dehydration and hypovolemia). 5.3 Falls Clozapine ODT may cause somnolence, postural hypotension, and motor and sensory instability, which may lead to falls and, consequently, fractures or other injuries. For patients with diseases, conditions, or medications that could exacerbate these effects, complete fall risk assessments when initiating antipsychotic treatment and recurrently for patients on long-term antipsychotic treatment. 5.4 Seizures Seizure has been estimated to occur in association with clozapine use at a cumulative incidence at one year of approximately 5%, based on the occurrence of one or more seizures in 61 of 1743 patients exposed to clozapine during its clinical testing prior to domestic marketing (i.e., a crude rate of 3.5%). The risk of seizure is dose-related. Initiate Clozapine ODT treatment with a low dose (12.5 mg), titrate slowly, and use divided dosing. Use caution when administering Clozapine ODT to patients with a history of seizures or other predisposing risk factors for seizure (e.g., head trauma or other CNS pathology, use of medications that lower the seizure threshold, or alcohol abuse). Because of the substantial risk of seizure associated with Clozapine ODT use, caution patients about engaging in any activity where sudden loss of consciousness could cause serious risk to themselves or others (e.g., driving an automobile, operating complex machinery, swimming, climbing). 5.5 Myocarditis, Pericarditis, Cardiomyopathy and Mitral Valve Incompetence Myocarditis, pericarditis, and cardiomyopathy have occurred with the use of clozapine. These reactions can be fatal. Discontinue Clozapine ODT and obtain a cardiac evaluation upon suspicion of myocarditis, pericarditis, or cardiomyopathy. Generally, patients with a history of clozapine-associated myocarditis, pericarditis or cardiomyopathy should not be rechallenged with Clozapine ODT. However, if the benefit of Clozapine ODT treatment is judged to outweigh the potential risks of recurrence, the clinician may consider rechallenge with Clozapine ODT in consultation with a cardiologist. Consider the possibility of myocarditis or cardiomyopathy in patients receiving Clozapine ODT who present with chest pain, dyspnea, persistent tachycardia at rest, palpitations, fever, flu-like symptoms, hypotension, other signs or symptoms of heart failure, or electrocardiographic findings (low voltages, ST-T abnormalities, arrhythmias, right axis deviation, and poor R wave progression). Myocarditis and pericarditis most frequently present within the first two months of clozapine treatment. Symptoms of cardiomyopathy generally occur later than clozapine-associated myocarditis and usually after 8 weeks of treatment. However, myocarditis, pericarditis, and cardiomyopathy can occur at any period during treatment with Clozapine ODT. In patients who are diagnosed with cardiomyopathy while taking clozapine, mitral valve incompetence has been reported. 5.6 Increased Mortality in Elderly Patients with Dementia-Related Psychosis Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of 17 placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group. Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality in this population. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear. Clozapine ODT is not approved for the treatment of patients with dementia-related psychosis [see] . 5.7 Gastrointestinal Hypomotility with Severe Complications Severe gastrointestinal adverse reactions have occurred with the use of clozapine, primarily due to its potent anticholinergic effects and resulting gastrointestinal hypomotility. In post marketing experience, reported effects range from constipation to paralytic ileus. Increased frequency of constipation and delayed diagnosis and treatment increased the risk of severe complications of gastrointestinal hypomotility, which can result in fecal impaction, megacolon, and intestinal obstruction, ischemia, infarction, perforation, ulceration, or necrosis [see Adverse Reactions (6.2) ] . These reactions have resulted in hospitalization, surgery, and death. The risk for severe adverse reactions is further increased with anticholinergic medications (and other medications that decrease gastrointestinal peristalsis); therefore, concomitant use should be avoided when possible [see Warnings and Precautions (5.15) , Drug Interactions (7.1) ] . Prior to initiating Clozapine ODT, screen for constipation and treat as necessary. Subjective symptoms of constipation may not accurately reflect the degree of gastrointestinal hypomotility in Clozapine ODT-treated patients. Therefore, reassess bowel function frequently with careful attention to any changes in the frequency or character of bowel movements, as well as signs and symptoms of complications of hypomotility (e.g., nausea, vomiting, abdominal distension, abdominal pain). If constipation or gastrointestinal hypomotility are identified, monitor closely and treat promptly with appropriate laxatives, as necessary, to prevent severe complications. Consider prophylactic laxatives in high risk patients. 5.8 Eosinophilia Eosinophilia, defined as a blood eosinophil count of greater than 700/μL, has occurred with clozapine treatment. In clinical trials, approximately 1% of patients developed eosinophilia. Clozapine-related eosinophilia usually occurs during the first month of treatment. In some patients, it has been associated with myocarditis, pancreatitis, hepatitis, colitis, and nephritis. Such organ involvement could be consistent with a drug reaction with eosinophilia and systemic symptoms syndrome (DRESS), also known as drug induced hypersensitivity syndrome (DIHS). If eosinophilia develops during Clozapine ODT treatment, evaluate promptly for signs and symptoms of systemic reactions, such as rash or other allergic symptoms, myocarditis, or other organ-specific disease associated with eosinophilia. If clozapine-related systemic disease is suspected, discontinue Clozapine ODT immediately. If a cause of eosinophilia unrelated to Clozapine ODT is identified (e.g., asthma, allergies, collagen vascular disease, parasitic infections, and specific neoplasms), treat the underlying cause and continue Clozapine ODT. Clozapine-related eosinophilia has also occurred in the absence of organ involvement and can resolve without intervention. There are reports of successful rechallenge after discontinuation of Clozapine ODT, without recurrence of eosinophilia. In the absence of organ involvement, continue Clozapine ODT under careful monitoring. If the total eosinophil count continues to increase over several weeks in the absence of systemic disease, the decision to interrupt Clozapine ODT therapy and rechallenge after the eosinophil count decreases should be based on the overall clinical assessment, in consultation with an internist or hematologist. 5.9 QT Interval Prolongation QT prolongation, Torsades de Pointes and other life-threatening ventricular arrhythmias, cardiac arrest, and sudden death have occurred with clozapine treatment. When prescribing Clozapine ODT, consider the presence of additional risk factors for QT prolongation and serious cardiovascular reactions. Conditions that increase these risks include the following: history of QT prolongation, long QT syndrome, family history of long QT syndrome or sudden cardiac death, significant cardiac arrhythmia, recent myocardial infarction, uncompensated heart failure, treatment with other medications that cause QT prolongation, treatment with medications that inhibit the metabolism of clozapine, and electrolyte abnormalities. Prior to initiating treatment with Clozapine ODT, perform a careful physical examination, medical history, and concomitant medication history. Consider obtaining a baseline ECG and serum chemistry panel. Correct electrolyte abnormalities. Discontinue Clozapine ODT if the QTc interval exceeds 500 msec. If patients experience symptoms consistent with Torsades de Pointes or other arrhythmias (e.g., syncope, presyncope, dizziness, or palpitations), obtain a cardiac evaluation and discontinue Clozapine ODT. Use caution when administering concomitant medications that prolong the QT interval or inhibit the metabolism of clozapine. Drugs that cause QT prolongation include: specific antipsychotics (e.g., ziprasidone, iloperidone, chlorpromazine, thioridazine, mesoridazine, droperidol, pimozide), specific antibiotics (e.g., erythromycin, gatifloxacin, moxifloxacin, sparfloxacin), Class 1A antiarrhythmic medications (e.g., quinidine, procainamide) or Class III antiarrhythmics (e.g., amiodarone, sotalol), and others (e.g., pentamidine, levomethadyl acetate, methadone, halofantrine, mefloquine, dolasetron mesylate, probucol or tacrolimus). Clozapine is primarily metabolized by CYP isoenzymes 1A2, 2D6, and 3A4. Concomitant treatment with inhibitors of these enzymes can increase the concentration of clozapine [see Drug Interactions (7.1) and Clinical Pharmacology (12.3) ] . Hypokalemia and hypomagnesemia increase the risk of QT prolongation. Hypokalemia can result from diuretic therapy, diarrhea, and other causes. Use caution when treating patients at risk for significant electrolyte disturbance, particularly hypokalemia. Obtain baseline measurements of serum potassium and magnesium levels, and periodically monitor electrolytes. Correct electrolyte abnormalities before initiating treatment with Clozapine ODT. 5.10 Metabolic Changes Atypical antipsychotic drugs, including clozapine, have been associated with metabolic changes that can increase cardiovascular and cerebrovascular risk. These metabolic changes include hyperglycemia, dyslipidemia, and body weight gain. While atypical antipsychotic drugs may produce some metabolic changes, each drug in the class has its own specific risk profile. Hyperglycemia and Diabetes Mellitus Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported in patients treated with atypical antipsychotics including clozapine. Assessment of the relationship between atypical antipsychotic use and glucose abnormalities is complicated by the possibility of an increased background risk of diabetes mellitus in patients with schizophrenia and the increasing incidence of diabetes mellitus in the general population. Given these confounders, the relationship between atypical antipsychotic use and hyperglycemia-related adverse reactions is not completely understood. However, epidemiological studies suggest an increased risk of treatment-emergent, hyperglycemia-related adverse reactions in patients treated with the atypical antipsychotics. Precise risk estimates for hyperglycemia-related adverse reactions in patients treated with atypical antipsychotics are not available. Patients with an established diagnosis of diabetes mellitus who are started on Clozapine ODT should be monitored regularly for worsening of glucose control. Patients with risk factors for diabetes mellitus (e.g., obesity, family history of diabetes) who are starting treatment with atypical antipsychotics should undergo fasting blood glucose testing at the beginning of treatment and periodically during treatment. Any patient treated with atypical antipsychotics should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Patients who develop symptoms of hyperglycemia during treatment with atypical antipsychotics should undergo fasting blood glucose testing. In some cases, hyperglycemia has resolved when the atypical antipsychotic was discontinued; however, some patients required continuation of anti-diabetic treatment despite discontinuation of the suspect drug. In a pooled data analysis of 8 studies in adult subjects with schizophrenia, the mean changes in fasting glucose concentration in the clozapine and chlorpromazine groups were +11 mg/dL and +4 mg/dL, respectively. A higher proportion of the clozapine group demonstrated categorical increases from baseline in fasting glucose concentrations, compared to the chlorpromazine group (Table 4). The clozapine doses were 100 to 900 mg per day (mean modal dose: 512 mg per day). The maximum chlorpromazine dose was 1800 mg per day (mean modal dose: 1029 mg per day). The median duration of exposure was 42 days for clozapine and chlorpromazine. Table 4: Categorical Changes in Fasting Glucose Level in Studies in Adult Subjects with Schizophrenia Laboratory Parameter Category Change (at least once) from Baseline Treatment Arm N n (%) Fasting Glucose Normal (< 100 mg/dL) to High (≥ 126 mg/dL) Clozapine 198 53 (27) Chlorpromazine 135 14 (10) Borderline (100 to 125 mg/dL) to High (≥ 126 mg/dL) Clozapine 57 24 (42) Chlorpromazine 43 12 (28) Dyslipidemia Undesirable alterations in lipids have occurred in patients treated with atypical antipsychotics, including clozapine. Clinical monitoring, including baseline and periodic follow-up lipid evaluations in patients using Clozapine ODT, is recommended. In a pooled data analysis of 10 studies in adult subjects with schizophrenia, clozapine treatment was associated with increases in serum total cholesterol. No data were collected on LDL and HDL cholesterol. The mean increase in total cholesterol was 13 mg/dL in the clozapine group and 15 mg/dL in the chlorpromazine group. In a pooled data analysis of 2 studies in adult subjects with schizophrenia, clozapine treatment was associated with increases in fasting serum triglyceride. The mean increase in fasting triglyceride was 71 mg/dL (54%) in the clozapine group and 39 mg/dL (35%) in the chlorpromazine group (Table 5). In addition, clozapine treatment was associated with categorical increases in serum total cholesterol and triglyceride, as illustrated in Table 6. The proportion of patients with categorical increases in total cholesterol or fasting triglyceride increased with the duration of exposure. The median duration of clozapine and chlorpromazine exposure was 45 days and 38 days, respectively. The clozapine dose range was 100 mg to 900 mg daily; the maximum chlorpromazine dose was 1800 mg daily.

Monitor weight during treatment with Clozapine ODT. Table 7 summarizes the data on weight gain by the duration of exposure pooled from 11 studies with clozapine and active comparators. The median duration of exposure was 609, 728, and 42 days, in the clozapine, olanzapine, and chlorpromazine group, respectively.

Clinical manifestations of NMS include hyperpyrexia, muscle rigidity, altered mental status, and autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmias). Associated findings can include elevated creatine phosphokinase (CPK), myoglobinuria, rhabdomyolysis, and acute renal failure. The diagnostic evaluation of patients with this syndrome is complicated. It is important to consider the presence of other serious medical conditions (e.g., severe neutropenia, infection, heat stroke, primary CNS pathology, central anticholinergic toxicity, extrapyramidal symptoms, and drug fever). The management of NMS should include (1) immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy, (2) intensive symptomatic treatment and medical monitoring, and (3) treatment of co-morbid medical conditions. There is no general agreement about specific pharmacological treatments for NMS. If a patient requires antipsychotic drug treatment after recovery from NMS, the potential reintroduction of drug therapy should be carefully considered. NMS can recur. Monitor closely if restarting treatment with antipsychotics. NMS has occurred with clozapine monotherapy and with concomitant CNS-active medications, including lithium. 5.12 Hepatotoxicity Severe, life threatening, and in some cases fatal hepatotoxicity including hepatic failure, hepatic necrosis, and hepatitis have been reported in patients treated with clozapine [see Adverse Reactions (6.2) ] . Monitor for the appearance of signs and symptoms of hepatotoxicity such as fatigue, malaise, anorexia, nausea, jaundice, bilirubinemia, coagulopathy, and hepatic encephalopathy. Perform serum tests for liver injury and consider permanently discontinuing treatment if hepatitis or transaminase elevations combined with other systemic symptoms are due to Clozapine ODT. 5.13 Fever During clozapine therapy, patients have experienced transient, clozapine-related fever. The peak incidence is within the first 3 weeks of treatment. While this fever is generally benign and self-limited, it may necessitate discontinuing treatment. The fever can be associated with an increase or decrease in WBC count. Carefully evaluate patients with fever to rule out severe neutropenia or infection [see Warnings and Precautions (5.1) ] . Consider the possibility of NMS [see Warnings and Precautions (5.11) ] . 5.14 Pulmonary Embolism Pulmonary embolism and deep vein thrombosis have occurred in patients treated with clozapine. Consider the possibility of pulmonary embolism in patients who present with deep vein thrombosis, acute dyspnea, chest pain, or with other respiratory signs and symptoms. Whether pulmonary embolus and deep vein thrombosis can be attributed to clozapine or some characteristic(s) of patients is not clear. 5.15 Anticholinergic Toxicity Clozapine ODT has potent anticholinergic effects. Treatment with Clozapine ODT can result in CNS and peripheral anticholinergic toxicity, especially at higher dosages, or in overdose situations [see Overdosage (10) ] . Use with caution in patients with a current diagnosis or prior history of constipation, urinary retention, clinically significant prostatic hypertrophy, or other conditions in which anticholinergic effects can lead to significant adverse reactions. When possible, avoid concomitant use with other anticholinergic medications because the risk for anticholinergic toxicity or severe gastrointestinal adverse reactions is increased [see Warnings and Precautions (5.7) , Drug Interactions (7.1) ] . 5.16 Interference with Cognitive and Motor Performance Clozapine ODT can cause sedation and impairment of cognitive and motor performance. Caution patients about operating hazardous machinery, including automobiles, until they are reasonably certain that Clozapine ODT does not affect them adversely. These reactions may be dose-related. Consider reducing the dose if they occur. 5.17 Tardive Dyskinesia Tardive dyskinesia (TD) has occurred in patients treated with antipsychotic drugs, including clozapine. The syndrome consists of potentially irreversible, involuntary, dyskinetic movements. The risk of TD and the likelihood that it will become irreversible are believed to increase with greater durations of treatment and higher total cumulative doses. However, the syndrome can develop after relatively brief treatment periods at low doses. Prescribe Clozapine ODT in a manner that is most likely to minimize the risk of developing TD. Use the lowest effective dose and the shortest duration necessary to control symptoms. Periodically assess the need for continued treatment. Consider discontinuing treatment if TD occurs. However, some patients may require treatment with Clozapine ODT despite the presence of the syndrome. TD may remit partially or completely if treatment is discontinued. Antipsychotic treatment, itself, may suppress (or partially suppress) the signs and symptoms, and it has the potential to mask the underlying process. The effect of symptom suppression on the long-term course of TD is unknown. 5.18 Patients with Phenylketonuria Phenylketonuric patients should be informed that Clozapine ODT contain phenylalanine (a component of aspartame). Each 25 mg, orally disintegrating tablet contains 1.90 mg phenylalanine. Each 100 mg, orally disintegrating tablet contains 7.59 mg phenylalanine. Each 150 mg, orally disintegrating tablet contains 11.38 mg phenylalanine. Each 200 mg, orally disintegrating tablet contains 15.18 mg phenylalanine. 5.19 Cerebrovascular Adverse Reactions In controlled trials, elderly patients with dementia-related psychosis treated with some atypical antipsychotics had an increased risk (compared to placebo) of cerebrovascular adverse reactions (e.g., stroke, transient ischemic attack), including fatalities. The mechanism for this increased risk is not known. An increased risk cannot be excluded for Clozapine ODT or other antipsychotics or other patient populations. Clozapine ODT should be used with caution in patients with risk factors for cerebrovascular adverse reactions. 5.20 Recurrence of Psychosis and Cholinergic Rebound after Abrupt Discontinuation of Clozapine ODT If abrupt discontinuation of Clozapine ODT is necessary (because of severe neutropenia or another medical condition, for example) [see Dosage and Administration (2.4) , Warnings and Precautions (5.1) ] , monitor carefully for the recurrence of psychotic symptoms and adverse reactions related to cholinergic rebound, such as profuse sweating, headache, nausea, vomiting, and diarrhea."],"nonclinical_toxicology":["13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis No carcinogenic potential was demonstrated in long-term studies in mice and rats at doses up to 0.3 times and 0.4 times, respectively, the maximum recommended human dose (MRHD) of 900 mg/day on a mg/m 2 body surface area basis. Mutagenesis Clozapine was not genotoxic when tested in the following gene mutation and chromosomal aberration tests: the bacterial Ames test, the in vitro mammalian V79 in Chinese hamster cells, the in vitro unscheduled DNA synthesis in rat hepatocytes, or the in vivo micronucleus assay in mice. Impairment of Fertility Clozapine had no effect on any parameters of fertility, pregnancy, fetal weight, or postnatal development when administered orally to male rats 70 days before mating and to female rats for 14 days before mating at doses up to 0.4 times the MRHD of 900 mg/day on a mg/m 2 body surface area basis."],"adverse_reactions_table":["<table ID=\"_RefID0ECNAI\"

Table 1: Clozapine ODT Dosage Modifications Based on ANC Results and Frequency of ANC Testing Recommended Dosage Modification Recommended Frequency of ANC Testing During Clozapine ODT Treatment ANC Within Normal Range (≥ 1500/µL) No dosage modification; continue treatment Day 1 to Month 6: Weekly Month 7 to Month 12: Every 2 weeks Month 13 and thereafter: Every month If Clozapine ODT treatment is reinitiated after a dosage interruption (e.g., patient had neutropenia which required dosage interruption and now has a normal ANC level) for: < 30 days, continue the previous ANC testing frequency ≥ 30 days, obtain ANC tests according to the frequency for patients who initiate treatment Mild Neutropenia (ANC between 1000 to 1499/µL) Confirm all initial reports of ANC less than 1500/µL with a repeat ANC measurement within 24 hours No dosage modification; continue treatment Three times weekly Once ANC ≥ 1500/µL, recommend returning to the patient’s last Normal Range ANC testing frequency Moderate Neutropenia (ANC between 500 to 999/µL) Interrupt treatment and recommend hematology consultation Resume treatment once ANC ≥ 1000/µL Daily Once ANC ≥ 1000/µL, three times weekly Once ANC ≥ 1500/µL, test weekly for 4 weeks. If ANC ≥ 1500/µL after monitoring weekly for 4 weeks, return to the patient’s last Normal Range ANC testing frequency Severe Neutropenia (ANC less than 500/µL) Discontinue treatment and recommend hematology consultation Daily Once ANC ≥ 1000/µL, three times weekly Once ANC ≥ 1500/µL, if the benefits outweigh the risks of restarting treatment, resume treatment and obtain ANC tests according to the frequency for patients who initiate treatment 2.4 Dosage Modifications Based on ANC Results for Patients with Benign Ethnic Neutropenia Table 2 provides recommended Clozapine ODT dosage modifications based on ANC results for patients with Benign Ethnic Neutropenia (BEN) (also known as Duffy-null associated neutrophil count) [see Warnings and Precautions (5.1) ] . For dosage modifications based on ANC results for patients without BEN, see Table 1 [see Dosage and Administration (2.3) ] . Table 2: Clozapine ODT Dosage Modifications Based on ANC Results and Frequency of ANC Testing in Patients with Benign Ethnic Neutropenia Benign Ethnic Neutropenia (BEN) is also known as Duffy-null associated neutrophil count. Recommended Dosage Modification Recommended Frequency of ANC Testing During Clozapine ODT Treatment in Patients with BEN ANC Within the Normal Range for Patients with BEN (≥ 1000/µL ) No dosage modification; continue treatment Day 1 to Month 6: Weekly Month 7 to Month 12: Every 2 weeks Month 13 and thereafter: Monthly If Clozapine ODT treatment is reinitiated after a dosage interruption (e.g., patient had neutropenia which required dosage interruption and now their ANC (≥ 1000/µL and ≥ the patient’s ANC baseline prior to treatment) for: < 30 days, continue previous ANC testing frequency ≥ 30 days, obtain ANC tests according to the frequency for patients with BEN who initiate treatment Neutropenia in Patients with BEN (ANC level between 500 to 999/µL) Confirm all initial reports of ANC less than 1500/µL with a repeat ANC measurement within 24 hours Recommend hematology consultation No dosage modification; continue treatment Three times weekly Once ANC ≥ 1000/µL and ≥ the patient’s ANC baseline, obtain ANC tests weekly for 4 weeks If ANC ≥ 1000/µL and ≥ the patient’s baseline after monitoring for 4 weeks, return to the patient’s last Normal ANC Range testing frequency for patients with BEN. Severe Neutropenia in Patients with BEN (ANC level less than 500/µL) Discontinue treatment and recommend hematology consultation Daily Once ANC ≥ 500/µL, obtain ANC three times weekly Once ANC ≥ 1000/µL and ≥ the patient’s baseline, if the benefits outweigh the risks of restarting treatment, resume treatment and obtain ANC tests according to the frequency for patients with BEN who initiate treatment 2.5 Discontinuation of Clozapine ODT Treatment If discontinuing Clozapine ODT in patients with: Moderate or severe neutropenia, see Table 1 [see Dosage and Administration (2.4) ] . Normal or mild neutropenia, reduce the dosage gradually over a period of 1 to 2 weeks, and continue monitoring ANC levels until their ANC is ≥ 1500/µL. If discontinuing Clozapine ODT in patients with Benign Ethnic Neutropenia (BEN) (also known as Duffy-null associated neutrophil count) with: Neutropenia, see Table 2 [see Dosage and Administration (2.5) ] . ANC within their normal range of ANC reduce the dosage gradually over a period of 1 to 2 weeks. When discontinuing Clozapine ODT, monitor patients for the symptoms related to psychotic recurrence and cholinergic rebound (e.g., profuse sweating, headache, nausea, vomiting, diarrhea). 2.6 Restarting Clozapine ODT Treatment After Interrupting Clozapine ODT When restarting Clozapine ODT in patients who have interrupted Clozapine ODT treatment, use a lower dosage to minimize the risk of hypotension, bradycardia, and syncope [see Warnings and Precautions (5.2) ] . If one day’s dosage is missed, resume Clozapine ODT treatment at 40% to 50% of the previous dosage. If two days of dosing is missed, resume Clozapine ODT treatment at approximately 25% of the previous dosage. For longer interruptions, restart Clozapine ODT treatment with a dosage of 12.5 mg once or twice daily. If this dosage is well-tolerated, may increase the dosage to the previous dosage more quickly than recommended than for initial Clozapine ODT treatment. 2.7 Dosage Modifications for Drug Interactions See Table 3 for recommended dosage modifications to reduce the risk of Clozapine ODT-associated adverse reactions or reduce the risk of lower effectiveness [see Drug Interactions (7) ] . Table 3: Clozapine ODT Dosage Modifications for Drug Interactions Strong CYP1A2 Inhibitors Administer one third of the Clozapine ODT dosage. Moderate or Weak CYP1A2 Inhibitors Consider reducing the Clozapine ODT dosage if necessary. CYP2D6 or CYP3A4 Inhibitors Strong CYP3A4 Inducers Concomitant use is not recommended. However, if concomitant use is necessary, it may be necessary to increase the Clozapine ODT dosage. Monitor for decreased effectiveness. Moderate or weak CYP1A2 or CYP3A4 Inducers Consider increasing the Clozapine ODT dosage if necessary. 2.8 Dosage Recommendations in Patients with Renal or Hepatic Impairment, or CYP2D6 Poor Metabolizers It may be necessary to reduce the Clozapine ODT dosage in patients with significant renal impairment or hepatic impairment, or in CYP2D6 poor metabolizers [see Use in Specific Populations (8.6 , 8.7) ] ."],"spl_product_data_elements":["Clozapine clozapine ASPARTAME CROSPOVIDONE (120 .MU.M) FD&C YELLOW NO. 6 MAGNESIUM STEARATE MANNITOL MICROCRYSTALLINE CELLULOSE 101 PEPPERMINT SILICON DIOXIDE SODIUM STEARYL FUMARATE CLOZAPINE CLOZAPINE peach C;100"],"dosage_forms_and_strengths":["3 DOSAGE FORMS AND STRENGTHS Clozapine Orally Disintegrating Tablets are available containing 25 mg, 100 mg, 150 mg or 200 mg of clozapine, USP.

( 8.2 ) 8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including Clozapine ODT, during pregnancy. Healthcare providers are encouraged to advise patients to register by calling the National Pregnancy Registry for Atypical Antipsychotics at1-866-961-2388 or visiting http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/. Risk Summary Neonates exposed to antipsychotic drugs, including Clozapine ODT, during the third trimester are at risk for extrapyramidal and/or withdrawal symptoms following delivery ( see Clinical Considerations ). Available data from published epidemiologic studies over decades of use with clozapine during pregnancy have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes ( see Data ). There are risks to the mother associated with untreated schizophrenia and with exposure to antipsychotics, including Clozapine ODT, during pregnancy ( see Clinical Considerations ). In animal reproduction studies, no adverse developmental effects were observed when clozapine was administered orally to pregnant rats or rabbits during the period of organogenesis, or to pregnant rats during pregnancy and lactation, at doses up to approximately 0.4 and 0.9 times the maximum recommended human dose (MRHD) of 900 mg/day, for rats and rabbits respectively, based on mg/m2 body surface area ( see Data ). The background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-associated maternal and/or embryo/fetal risk There is a risk to the mother from untreated schizophrenia, including increased risk of relapse, hospitalization, and suicide. Schizophrenia is associated with increased adverse perinatal outcomes, including preterm birth. It is not known if this is a direct result of the illness or other comorbid factors. Fetal/Neonatal adverse reactions Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder have been reported in neonates who have been exposed to antipsychotic drugs, including Clozapine ODT, during the third trimester of pregnancy. These symptoms have varied in severity. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. Data Animal Data In embryofetal developmental studies, clozapine had no effects on maternal parameters, litter sizes, or fetal parameters when administered orally to pregnant rats and rabbits during the period of organogenesis at doses up to 0.4 and 0.9 times, respectively, the MRHD of 900 mg/day on a mg/m 2 body surface area basis. In peri/postnatal developmental studies, pregnant female rats were administered clozapine over the last third of pregnancy and until day 21 postpartum. Observations were made on fetuses at birth and during the postnatal period; the offspring were allowed to reach sexual maturity and mated. Clozapine caused a decrease in maternal body weight but had no effects on litter size or body weights of either F1 or F2 generations at doses up to 0.4 times the MRHD of 900 mg/day on a mg/m 2 body surface area basis. 8.2 Lactation Risk Summary Clozapine is present in human milk. There is one case report of sedation and a report of agranulocytosis in an infant exposed to clozapine through human milk (see Clinical Considerations ) . There is no information on the effects of clozapine on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Clozapine ODT and any potential adverse effects on the breastfed child from Clozapine ODT or from the underlying maternal condition. Clinical Considerations Infants exposed to Clozapine ODT should be monitored for excess sedation and neutropenia. 8.4 Pediatric Use Safety and effectiveness of clozapine in pediatric patients have not been established. 8.5 Geriatric Use There have not been sufficient numbers of geriatric patients in clinical studies utilizing clozapine to determine whether those over 65 years of age differ from younger subjects in their response to clozapine. Orthostatic hypotension and tachycardia can occur with Clozapine ODT treatment [seeand Warnings and Precautions (5.2) ] . Elderly patients, particularly those with compromised cardiovascular functioning, may be more susceptible to these effects. Elderly patients may be particularly susceptible to the anticholinergic effects of Clozapine ODT, such as urinary retention and constipation [see Warnings and Precautions (5.15) ] . Carefully select Clozapine ODT doses in elderly patients, taking into consideration their greater frequency of decreased hepatic, renal, or cardiac function, as well as other concomitant disease and other drug therapy. Clinical experience suggests that the prevalence of tardive dyskinesia appears to be highest among the elderly; especially elderly women [see Warnings and Precautions (5.17) ] . 8.6 Patients with Renal or Hepatic Impairment Dose reduction may be necessary in patients with significant impairment of renal or hepatic function. Clozapine concentrations may be increased in these patients, because clozapine is almost completely metabolized and then excreted [see Dosage and Administration (2.8) , Clinical Pharmacology (12.3) ] . 8.7 CYP2D6 Poor Metabolizers Dose reduction may be necessary in patients who are CYP2D6 poor metabolizers. Clozapine concentrations may be increased in these patients, because clozapine is almost completely metabolized and then excreted [see Dosage and Administration (2.8) , Clinical Pharmacology (12.3) ]

Prior to initiating Clozapine ODT treatment, obtain baseline ANC(s). Clozapine ODT initiation is not recommended in patients with a baseline ANC less than 1500/µL (less than 1000/µL for those with Benign Ethnic Neutropenia (also known as Duffy-null associated neutrophil count)). See recommendations for dosage modifications based on ANC levels during Clozapine ODT treatment [see Dosage and Administration (2.4 , 2.5) ] . Consider a hematology consultation before initiating Clozapine ODT or during Clozapine ODT treatment [see Warnings and Precautions (5.1) ] . Orthostatic Hypotension, Bradycardia, Syncope Orthostatic hypotension, bradycardia, syncope, and cardiac arrest have occurred with clozapine treatment. The risk is highest during the initial titration period, particularly with rapid dose escalation. These reactions can occur with the first dose, with doses as low as 12.5 mg per day, or when restarting patients who have had even a brief interruption in treatment with Clozapine ODT. Initiate treatment at 12.5 mg once or twice daily; titrate slowly; and use divided dosages to minimize risk. Use Clozapine ODT cautiously in patients with cardiovascular or cerebrovascular disease or conditions predisposing to hypotension (e.g., dehydration, use of antihypertensive medications) [see Dosage and Administration (2.3 and 2.6) , Warnings and Precautions (5.2) ] . Seizures Seizures have occurred with clozapine treatment. The risk is dose-related. Initiate treatment at 12.5 mg, titrate gradually, and use divided dosing. Use caution when administering Clozapine ODT to patients with a history of seizures or other predisposing risk factors for seizure (CNS pathology, medications that lower the seizure threshold, alcohol abuse). Caution patients about engaging in any activity where sudden loss of consciousness could cause serious risk to themselves or others [see Dosage and Administration (2.3) , Warnings and Precautions (5.4) ] . Myocarditis, Pericarditis, Cardiomyopathy and Mitral Valve Incompetence Fatal myocarditis and cardiomyopathy have occurred with clozapine treatment. Discontinue Clozapine ODT and obtain a cardiac evaluation upon suspicion of these reactions. Generally, patients with clozapine-related myocarditis or cardiomyopathy should not be rechallenged with Clozapine ODT. Consider the possibility of myocarditis, pericarditis, or cardiomyopathy if chest pain, tachycardia, palpitations, dyspnea, fever, flu-like symptoms, hypotension, or ECG changes occur [see Warnings and Precautions (5.5) ] . Increased Mortality in Elderly Patients with Dementia-Related Psychosis Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Clozapine ODT is not approved for use in patients with dementia-related psychosis [see Warnings and Precautions (5.6) ] .

Severe Neutropenia: Clozapine has caused severe neutropenia, which is associated with an increased risk of serious and fatal infections. Prior to initiating Clozapine Orally Disintegrating Tablets (Clozapine ODT) treatment, obtain baseline ANC(s). Clozapine ODT initiation is not recommended in patients with a baseline ANC less than 1500/μL (less than 1000/μL for those with Benign Ethnic Neutropenia (also known as Duffy-null associated neutrophil count)). See recommendations for dosage modifications based on ANC levels during Clozapine ODT treatment. ( 2.1 , 2.3 , 2.4 , 5.1 ) Orthostatic Hypotension, Bradycardia, and Syncope: Risk is dose-related. Starting dose is 12.5 mg. Titrate gradually and use divided dosages. ( 2.2 , 5.2 ) Seizure: Risk is dose-related. Titrate gradually and use divided doses. Use with caution in patients with history of seizure or risk factors for seizure. ( 5.4 ) Myocarditis, Pericarditis, Cardiomyopathy and Mitral Valve Incompetence: Can be fatal. Discontinue and obtain cardiac evaluation if findings suggest these cardiac reactions.

It is used primarily to treat people with schizophrenia and schizoaffective disorder who have had an inadequate response to two other antipsychotics, or who have been unable to tolerate other drugs due to extrapyramidal side effects. In the US, clozapine is also approved for use in people with recurrent suicidal behavior in people with schizophrenia or schizoaffective disorder. It is also used for the treatment of psychosis in Parkinson's disease.","wiki_history":"==History==\nClozapine was synthesized in 1958 by Wander AG, a Swiss pharmaceutical company, based on the chemical structure of the tricyclic antidepressant imipramine. The first test in humans in 1962 was considered a failure. Trials in Germany in 1965 and 1966 as well as a trial in Vienna in 1966 were successful. In 1967, Wander AG was acquired by Sandoz. Analysis of the Finnish cases revealed that all the agranulocytosis cases had occurred within the first 18 weeks of treatment and the authors proposed blood monitoring during this period. The rate of agranulocytosis in Finland appeared to be 20 times higher than in the rest of the world and there was speculation that this may have been due a unique genetic variant in the region. Whilst the drug continued to be manufactured by Sandoz, and remained available in Europe, development in the U.S. halted.\n\nInterest in clozapine continued in an investigational capacity in the United States because, even in the 1980s, the duration of hospitalization, especially in state hospitals for those with treatment resistant schizophrenia, might often be measured in years rather than days. The role of clozapine in treatment-resistant schizophrenia was established by the landmark Clozaril Collaborative Study Group Study #30 in which clozapine showed marked benefits compared to chlorpromazine in a group of patients with protracted psychosis and who had already shown an inadequate response to other antipsychotics. This involved both stringent blood monitoring and a double-blind design with the power to demonstrate superiority over standard antipsychotic treatment. The inclusion criteria were patients who had failed to respond to at least three previous antipsychotics and had then not responded to a single blind treatment with haloperidol (mean dose 61&nbsp;mg +/− 14&nbsp;mg/d). Two hundred and sixty-eight were randomised were to double blind trials of clozapine (up to 900&nbsp;mg/d)  or chlorpromazine (up to 1800&nbsp;mg/d). 30% of the ","wiki_society_and_culture":"== Society and culture ==\n=== Underuse ===\nClozapine is widely recognised as being underused with wide variation in prescribing, especially in patients with African heritage.\n\nPsychiatrists' prescribing practices have been found to be the most significant variable regarding variance in its use. Surveys of psychiatrists' attitudes to clozapine have found that many had little experience in its use, overestimated the incidence of side effects, and did not appreciate that many patients prefer to take clozapine over other antipsychotics. In contrast to many psychiatrists' expectations most patients believe that the blood testing and other difficulties are worth the multiple benefits that they perceive. Whilst psychiatrists fear the severe adverse effects such as agranulocytosis, patients are more concerned about hypersalivation. Clozapine is no longer actively marketed and this may also be one of the explanations for its underuse.\n\nDespite the strong evidence and universal endorsement by national and international treatment guidelines and the experiences of patients themselves, most people eligible for clozapine are not treated with it. Those patients that do start clozapine usually face prolonged delay, multiple episodes of psychosis and treatments such as high dose antipsychotics or polypharmacy. Instead of two previous antipsychotics many will have been exposed to ten or more drugs which were not effective. A study of 120 patients conducted in four hospitals in South-East London found a mean of 9.2 episodes of antipsychotic prescription before clozapine was initiated and the mean delay in using clozapine was 5 years. Treatments that have no evidence base or are regarded as actively harmful are used instead.\n\nAs well as variation within counties there is massive variation in the use of clozapine internationally. An international study of 17 counties found greatest use in Finland (189/100,000 persons) and New Zealand (116/100,000), and least in the Japanese cohort (0.6/"},"commercial":{"launchDate":"1989","_launchSource":"DrugCentral (FDA 1989-09-26, NOVARTIS)"},"references":[{"id":1,"url":"https://drugcentral.org/drugcard/722","fields":["approvals","synonyms","ATC","PK","indications","contraindications","DDIs","targets","patents","FAERS"],"source":"DrugCentral"},{"id":2,"url":"https://clinicaltrials.gov/search?intr=CLOZAPINE","fields":["trials"],"source":"ClinicalTrials.gov"},{"id":3,"url":"https://pubmed.ncbi.nlm.nih.gov/?term=CLOZAPINE","fields":["publications"],"source":"PubMed/NCBI"},{"id":4,"url":"https://en.wikipedia.org/wiki/Clozapine","fields":["history","overview"],"source":"Wikipedia"},{"id":5,"url":"https://www.fda.gov/drugs/drug-approvals-and-databases/orange-book-data-files","fields":["patents","exclusivity","genericManufacturers"],"source":"FDA Orange Book"}],"_enrichedAt":"2026-03-30T10:15:03.194978","_validation":{"fieldsValidated":2,"lastValidatedAt":"2026-04-20T00:49:59.654049+00:00","fieldsConflicting":1,"overallConfidence":0.8},"biosimilars":[],"competitors":[{"drugName":"loxapine","drugSlug":"loxapine","fdaApproval":"1975-02-25","patentExpiry":"Oct 23, 2026","patentStatus":"Patent protected","relationship":"same-class"},{"drugName":"olanzapine","drugSlug":"olanzapine","fdaApproval":"1996-09-30","genericCount":34,"patentStatus":"Off-patent — generic available","relationship":"same-class"},{"drugName":"quetiapine","drugSlug":"quetiapine","fdaApproval":"1997-09-26","genericCount":27,"patentStatus":"Off-patent — generic available","relationship":"same-class"},{"drugName":"asenapine","drugSlug":"asenapine","fdaApproval":"2009-08-13","patentExpiry":"Sep 22, 2033","patentStatus":"Patent protected","relationship":"same-class"},{"drugName":"samidorphan","drugSlug":"samidorphan","fdaApproval":"2021-05-28","relationship":"same-class"}],"dataSources":[{"url":"https://data.medicaid.gov/dataset/4j6z-xnwq","name":"CMS National Average Drug Acquisition Cost (NADAC)","fields":["pricing"],"retrievedDate":"2026-04-07"}],"genericName":"clozapine","indications":{"approved":[{"name":"Suicidal Behavior in Schizoaffective Disorder","source":"DrugCentral","snomedId":"","regulator":"FDA","eligibility":"Patients with schizophrenia or schizoaffective disorder who are judged to be at chronic risk for re-experiencing suicidal behavior, based on history and recent clinical state."},{"name":"Suicidal Behavior in Schizophrenia","source":"DrugCentral","snomedId":"","regulator":"FDA","eligibility":"Patients with schizophrenia or schizoaffective disorder who are judged to be at chronic risk for re-experiencing suicidal behavior, based on history and recent clinical state.","usPrevalence":2800000,"globalPrevalence":24000000,"prevalenceMethod":"curated","prevalenceSource":"WHO, 2022"},{"name":"Treatment-Resistant Schizophrenia","source":"DrugCentral","snomedId":"","regulator":"FDA","eligibility":"Severely ill patients with schizophrenia who fail to respond adequately to standard antipsychotic treatment.
