Methorphan

 ( Morphinans ) 

Methorphan is an opioid drug that occurs in two isomeric drug form, each with differing pharmacology and effects:

• Dextromethorphan An over-the-counter cough suppressant, as well as dissociative hallucinogen.
• Levomethorphan A potent opioid analgesic that was never drug development; a prodrug of the powerful opioid agonist analgesic levorphanol (Levo-Dromoran).

Racemethorphan is the racemic mixture of both of these stereoisomers. It is listed under the Single Convention on Narcotic Drugs 1961 and is therefore listed in the United States as a Controlled Substance, specifically as a Narcotic in Schedule II with an ACSCN of 9732 and an annual aggregate manufacturing quota of 3 grams in 2014.

The salts in use are the hydrobromide (free base conversion ratio 0.770) and the tartrate (0.644).
