2-MDP (U-23807A) is a dissociative anaesthetic drug which has been found to be an NMDA antagonist and produces similar effects to PCP in animals. The levo or (-) isomer is the active form of the drug. It also has stimulant effects having only around one third the potency of amphetamine by weight but with a long duration of action lasting more than 24 hours from a single oral dose.
