Dextrorphan (also known as DXO) is a dissociative drug of the morphinan class. It's the main active metabolite of dextromethorphan (DXM). It appears as a colorless powder.[1]

Chemistry

Dextrorphan is a dextrorotatory molecule of the morphinan class. It contains a phenanthrene core structure with one aromatic ring (benzene) bound to two saturated rings (cyclohexane). Dextromethorphan is metabolized in the body by o-demethylation through the CYP2D6 enzyme to form Dextrorphan.[2]

Pharmacology

The pharmacology of dextrorphan is similar to that of dextromethorphan (DXM). However, dextrorphan is much more potent as an NMDA receptor antagonist as well as essentially inactive as a serotonin reuptake inhibitor.[3] DXO is an active chemical and contributes to the subjective effects experienced when active doses of DXM are consumed.[4]

Binding affinities (Ki)

  • NMDA antagonist - 486 nM
  • Sigma-1 agonist - 351 nM
  • Serotonin transporter (SERT) - 484 nM
  • Mu opioid agonist - 420 nM

Subjective effects

Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), a literature which relies on collected anecdotal reports and the personal experiences of PsychonautWiki contributors. As a result, they should be taken with a healthy amount of skepticism. It is worth noting that these effects will not necessarily occur in a consistent or reliable manner, although higher doses (common+) are more likely to induce the full spectrum of reported effects. Likewise, adverse effects become much more likely with higher doses and may include serious injury or death.

One user reported excessive itchiness accompanied by a "peaceful yet emotionless state" after 340mg of the substance was consumed.[5]
