Dextrallorphan (DXA) is a drug of the morphinan class known in scientific research. It acts as a σ1 receptor agonist and NMDA receptor antagonist.[1][2][3][4] It has no significant affinity for the σ2, μ-opioid, or δ-opioid receptor, or for the serotonin or norepinephrine transporter.[5][2] As an NMDA receptor antagonist, in vivo, it is approximately twice as potent as dextromethorphan, and five-fold less potent than dextrorphan.[3]
