Phendimetrazine

Phendimetrazine (Bontril®) is a weight loss medication. Phendimetrazine is chemically related to amphetamines and is a Schedule III drug under the Convention on Psychotropic Substances. In the United States, phendimetrazine is a Schedule III controlled substance under the Uniform Controlled Substances Act of 1970.

Phendimetrazine is used clinically in the form of phendimetrazine tartrate.



Approximately 30% of a given dose of phendimetrazine is metabolized into phenmetrazine, which may account for part of its anorectic effect, and probably also influences abuse potential; individuals who metabolise a greater proportion of phendimetrazine into phenmetrazine are more likely to develop problems with dependence and addiction.

According to the "List of psychotropic substances under international control," phendimetrazine is a Schedule IV controlled substance.
