Methoxphenidine (methoxyphenidine, MXP, 2-MXP, 2-MeO-Diphenidine) is a dissociative drug that has been sold online as a research chemical.[1] Methoxphenidine was first reported in a 1989 patent where it was tested as a treatment for neurotoxic injury.[2] Shortly after the 2013 UK ban on arylcyclohexylamines methoxphenidine and the related compound diphenidine became available on the gray market, where it has been encountered as a powder and in tablet form.[3] Though diphenidine possesses higher affinity for the NMDA receptor, anecdotal reports suggest methoxphenidine has greater oral potency.[1] Of the three isomeric anisyl-substituents methoxphenidine has affinity for the NMDA receptor that is higher than 4-MeO-diphenidine but lower than 3-MeO-diphenidine,[2] a structure–activity relationship shared by the anisylcyclohexylamines.

Acute methoxphenidine intoxication has been reported to produce confusion, hypertension, and tachycardia that was responsive to treatment with intravenous lorazepam,[4] methoxphenidine has also been associated with three published fatalities.[5]
