Dextrorphan Systematic (IUPAC) name (+)-17-methyl- 9a,13a,14a-morphinan- 3-ol Clinical data Pregnancy cat. ? Legal status ? (US) Identifiers CAS number 125-73-5 ATC code None PubChem CID 5360697 UNII 04B7QNO9WS ChEMBL CHEMBL341216 Chemical data Formula C17H23NO Mol. mass 257.371 g/mol (what is this?) (verify) Dextrorphan (DXO) is a psychoactive drug of the morphinan chemical class which acts as an antitussive or cough suppressant and dissociative hallucinogen. It is the dextro-stereoisomer of racemorphan, the levo-half being levorphanol. Dextrorphan is produced by O-demethylation of dextromethorphan by CYP2D6. Dextrorphan is an NMDA antagonist and contributes to the abuse liability of dextromethorphan.[1]

Pharmacology
- Noncompetitive N-methyl-D-aspartate receptor (NMDAR) antagonist.[2][3][4]
- σ1 and σ2 sigma receptor agonist.[5][6]
- α3β4, α4β2, and α7 nicotinic acetylcholine receptor antagonist.[7][8]
- L-type voltage-gated calcium channel (LVGCC) blocker.[4][9]
The pharmacology of dextrorphan is similar to that of dextromethorphan (DXM). However, dextrorphan is much more potent as an NMDA receptor antagonist and much weaker as a serotonin reuptake inhibitor, producing a noticeably more body-affecting, "stoned" feeling[10].
Legality
Dextrorphan was formerly a Schedule I controlled substance in the United States, but was unscheduled on October 1, 1976.[11]
