- DextrorphanTemplate:Snd an antitussive and dissociative hallucinogen (NMDA receptor antagonist)
- LevorphanolTemplate:Snd an opioid analgesic
It analgesic activity is intermediate between Dextrorphan and Levorphanol.[1]
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).
