Pharmacology
Mechanism of Action: DXM acts as a noncompetitive antagonist at the N-methyl-D-aspartate (NMDA) receptor and a sigma-1 receptor agonist, producing dissociative effects.
Metabolism: Metabolized in the liver primarily by CYP2D6 enzyme to form dextrorphan, the active metabolite.
Half-life: Approximately 3-4 hours, with effects typically lasting 6-8 hours.
Bioavailability: ~80% when taken orally, with peak plasma concentrations reached within 1-2 hours.
Risks and Harm Reduction
⚠️ Important: Always practice harm reduction. Start with low doses, test your substances, and ensure a safe set and setting. Never use alone.
