Levomethorphan

Levomethorphan (INN, BAN) is an opioid analgesic of the morphinan family that has never been marketed. It is the L-stereoisomer of racemethorphan (methorphan). The effects of the two isomers of the racemethorphan are quite different, with dextromethorphan (DXM) contrarily being an antitussive at low doses and a dissociative hallucinogen at much higher doses.
