Racemorphan, or morphanol, is the racemic mixture of the two stereoisomers of 17-methylmorphinan-3-ol, each with differing pharmacology and effects:

Dextrorphan – an antitussive and dissociative hallucinogen (NMDA receptor antagonist)
Levorphanol – an opioid analgesic

Racemorphan itself is under international control per the Single Convention on Narcotic Drugs 1961 and is therefore listed as a Schedule II Narcotic controlled substance in the US Controlled Substances Act 1970; it has an ACSCN of 9733 and in 2014 it had an aggregate annual manufacturing quota of zero. ^[2] The salts in use are hydrobromide (free base conversion ratio 0.741), hydrochloride (0.876), and tartrate (0.632).
