Anorectic Drugs
A number of drugs have been developed and marketed to replace
amphetamines as appetite suppressants. These anorectic drugs
include benzphetamine (Didrex®), diethylproprion (Tenuate®,
Tepanil®), mazindol (Sanorex®, Mazanor®), phendimetrazine
(Bontril®, Prelu-27®), and phentermine (lonamin®, Fastin®,
Adipex®). These substances are in Schedule III or IV of the CSA
and produce some amphetamine-like effects. Of these diet pills,
phentermine is the most widely prescribed and most frequently
encountered on the illicit market. Two Schedule IV 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.
