Talk:Dextrorphan
Dextrorphan (DXO) is the pro-drug for Dextromethorphan. This means that it is metabolized in the body from DXM to form DXO, both of which are active chemicals which contribute towards the experience of subjective effects. 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.[1]
