Pharmacology

Phendimetrazine functions as a prodrug to phenmetrazine; approximately 30 percent of an oral dose is converted into it. Phendimetrazine can essentially be thought of as an extended-release formulation of phenmetrazine with less potential for abuse. Phenmetrazine acts as a norepinephrine-dopamine releasing agent (NDRA).[2]

Its structure incorporates the backbone of methamphetamine, a potent CNS stimulant. While the addition of an N-methyl group to amphetamine significantly increases its potency and bioavailability, methylation of phendimetrazine renders the compound virtually inactive. Metabolization by demethylases produces a steady, continuous activation of the drug in the body, both lowering abuse potential and allowing for once-daily administration.

Legality

According to the List of Psychotropic Substances under International Control published by the International Narcotics Control Board, phendimetrazine is a Schedule III controlled substance under the Convention on Psychotropic Substances.[3]
