Quetiapine 600mg
Quetiapine is an atypical antipsychotic that acts as a serotonin and dopamine receptor antagonist.
Quetiapine 600mg, marketed by AstraZeneca, is an atypical antipsychotic used primarily for the treatment of schizophrenia and bipolar disorder. It works by modulating dopamine and serotonin receptors in the brain, helping to stabilize mood and reduce psychotic symptoms. Despite its efficacy, quetiapine has a range of side effects, including somnolence, dizziness, and weight gain, which can impact patient adherence. The drug is also under investigation for additional indications, such as major depressive disorder. Safety concerns include warnings about increased mortality in elderly patients with dementia-related psychosis.
