Medical uses
Methadone is used for the treatment of opioid use disorder. It may be used as maintenance therapy or in shorter periods for detoxification to manage opioid withdrawal symptoms. Its use for the treatment of addiction is usually strictly regulated.

Pharmacology
Methadone acts by binding to the µ-opioid receptor, but also has some affinity for the NMDA receptor, an ionotropic glutamate receptor. Methadone is metabolized by CYP3A4, CYP2B6, CYP2D6, and is a substrate, or in this case target, for the P-glycoprotein efflux protein, a protein which helps pump foreign substances out of cells, in the intestines and brain. The bioavailability and elimination half-life of methadone are subject to substantial interindividual variability. Its main route of admin…
Chemistry
Methadone and its major metabolite, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), are often measured in urine as part of a drug abuse testing program, in plasma or serum to confirm a diagnosis of poisoning in hospitalized victims, or in whole blood to assist in a forensic investigation of a traffic or other criminal violation or a case of sudden death. Methadone usage history is considered in interpreting the results as a chronic user can develop tolerance to dose…
