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. The salts in use are hydrobromide (free base conversion ratio 0.741), hydrochloride (0.876), and tartrate (0.632).
