Mechanism of action

The most common marketed medications for opioid use disorder include methadone (a full mu-opioid agonist that prevents withdrawal and reduces cravings), buprenorphine (a partial mu-opioid agonist with lower overdose risk), and naltrexone (a mu-opioid antagonist that blocks opioid effects). These agents target opioid receptors in the central nervous system to either substitute for illicit opioids, reduce withdrawal symptoms, or prevent reinforcement of opioid use.
