Methadone: MedlinePlus Drug Information

The cognitive deficits model of drug addiction proposes that individuals who develop addictive disorders have abnormalities in an area of the brain called the prefrontal cortex (PFC). The PFC is important for regulation of judgment, planning, and other executive functions. To help us overcome some of our impulses for immediate gratification in favor of more important or ultimately more rewarding long-term goals, the PFC sends inhibitory signals to the VTA DA neurons of the mesolimbic reward system. The locus ceruleus (LC) is an area of the brain that is critically involved in the production of opioid dependence and withdrawal.

Overdoses are unpredictable and can occur regardless of how long you’ve been taking opioids or how high your tolerance is.

A longer acting derivative of methadone, LAAM can be given three times per week. Recent concerns about heart rhythm problems (specifically, prolonged QT interval) have limited LAAM’s use (U.S. Food and Drug Administration, 2001). Dosing with LAAM is highly individualized, and three-times-weekly doses range from 40 mg to 140 mg.

Patients are generally started on a daily dose of 20 mg to 30 mg, with increases of 5 mg to 10 mg until a dose of 60 mg to 100 mg per day is achieved. The higher doses produce full suppression of opioid craving and, consequently, opioid-free urine tests (Judd et al., 1998). Patients generally stay on methadone for 6 months to 3 years, some much longer. Relapse is common among patients who discontinue methadone after only 2 years or less, and many patients have benefited from lifelong methadone maintenance.
