What are they ?
Anorectics are diet pills, developed and marketed to replace amphetamines as appetite suppressants. They include:
     • benzphetamine (Didrex)
     • diethylproprion (Tenuate, Tepanil)
     • fenfluramine (Pondimin)
     • mazindol (Sanorex, Mazanor)
     • phendimetrazine (Bontril, Prelu-2, Plegine)
     • phentermine (Ionamin, AdipexP)

   Of these pills, phentermine is the most widely prescribed and most frequently encountered on the illicit market.

Short Term Effects
Anorectics speed up the central nervous system (brain and spinal cord), producing many of the effects of amphetamines, but are generally less potent. All are controlled substances because of their amphetamine like effects.

What are their dangers ?
Two anorectics often used in combination with phentermine (phen-fen combo), fenfluramine and dexfenfluramine, were removed from the U.S. market due to heart valve problems. The dangers with the abuse of this class of drugs are similar to those of amphetamines. Excessive weight loss is also dangerous.
