Methadone (Pakistan)

Methadone (Dolophine, Amidone, Methadose, Physeptone, Heptadon and many others) is a synthetic opioid, used medically as an analgesic, antitussive and a maintenance anti-addictive for use in patients on opioids. It was developed in Nazi Germany in 1937. Although chemically unlike morphine or heroin, methadone also acts on the opioid receptors and thus produces many of the same effects. Methadone is also used in managing chronic pain due to its long duration of action and very low cost.
