Note: "Anorexic" is also a term for a person with anorexia or loss of appetite, or the eating disorder anorexia nervosa

An anorectic or anorexic (from the Greek an- = "without" and orexis = "appetite"), also known as anorexigenic or appetite suppressant, is a dietary supplements and/or drug which reduces appetite, food consumption, and as a result, causes weight loss to occur.


List of Anorectics

Numerous pharmaceutical compounds are marketed as appetite suppressants.

The following drugs listed as "centrally-acting antiobesity preparations" by ATC:[1]

The following are listed as appetite depressants by MeSH.[2]

Other compounds marked as appetite suppressants include:

Public Health Concerns

Epidemics of fatal pulmonary hypertension and heart valve damage associated with pharmaceutical anorectic agents have led to the withdrawal of products from the market. This was the case with aminorex in the 1960s, and again in the 1990s with fenfluramine (see: Fen-phen).[3] Likewise, association of the related appetite suppressant phenylpropanolamine with hemorrhagic stroke led the Food and Drug Administration (FDA) to request its withdrawal from the market in the United States in 2000, and similar concerns regarding ephedrine resulted in an FDA ban on its inclusion in dietary supplements, in 2004 (a Federal judge later overturned this ban in 2005 during a challenge by supplement maker Nutraceuticals). It is also debatable as to whether the ephedrine ban had more to do with its use as a precursor in methamphetamine manufacture rather than legitimate health concerns.

History and Initial Uses

Used on a short term basis clinically to treat obesity, some appetite suppressants are also available over-the-counter. In the United States, appetite suppressants don't have to be approved by the FDA when they are based on a 100% natural basis. There are all kinds of natural appetite suppressants (supplements) on the market helping people to control and limit their food intake. Most common natural appetite suppressants are based on hoodia a genus of 13 species in the flowering plant family Apocynaceae, under the subfamily Asclepiadoideae. Also widely used as a basis is green tea with other plant extracts to limit calorie intake. A lot of appetite suppressants are based on a mix of natural ingredients mostly using green tea as its basis with a combination/mix of other plant extracts like fucoxanthin, found naturally in seaweed. Drugs of this class are frequently stimulants of the phenethylamine family, related to amphetamine (informally known as speed).

The German military experimented with issuing amphetamines to soldiers in 1945, when food supplies were very short in Germany. Following the Second World War, amphetamines were re-directed for use on the civilian market. Indeed, amphetamine itself was sold commercially as an appetite suppressant until it was outlawed in most parts of the world in the late 1950s due to increased recreational use. Many amphetamines produce side effects including addiction, tachycardia and hypertension,[4] making prolonged unsupervised use dangerous.
