Isomethadone (INN, BAN; Liden), also known as isoamidone, is a synthetic opioid analgesic and antitussive related to methadone that was used formerly as a pharmaceutical drug but is now no longer marketed.[1][2][3][4] It binds to and activates both the μ- and δ-opioid receptors, with the (S)-isomer being the more potent of its two enantiomers.[5] Isomethadone is a Schedule II controlled substance in the United States, and is also regulated internationally as a Schedule I controlled substance under the United Nations Single Convention on Narcotic Drugs of 1961.[6]
