What is it?

A number of drugs have been developed and marketed to replace amphetamines as appetite suppressants. These anorectic drugs include benzphetamine (Didrex), diethylproprion (Tenuate, Tepanil), fenfluramine (Pondimin), mazindol (Sanorex, Mazanor), phendimetrazine (Bontril, Prelu-2, Plegine) and phentermine (Ionamin, AdipexP).

What are its short-term effects?

They produce many of the effects of the amphetamines, but are generally less potent. All are controlled substances because of the similarity of their effects to those of the amphetamines.
