This term derives from Greek (a + oregein, meaning "not to reach for"; later, anorektos ) and it refers to a substance that reduces food intake. It came into use in English about 1900. Anorectic agents (also referred to as anorexics, anorexegenics, or appetite suppressants) fall into a number of categories according to the brain neurotransmitter system through which they work.
Central nervous system (CNS) stimulants that act through the noradrenergic and dopaminergic systems include Cocaine, amphetamine-like compounds, mazindol, and phenylpropanalamine. Serotonergic compounds include fenfluramine, fluoxetine, and sertraline. Several endogenous peptides (within the body) also have anorectic actions, in that they inhibit food intake—these include cholecystokinin, glucagon, and the bombesin-like peptides.
Not all agents that can suppress appetite are medically approved for such use. For example, cocaine is approved only as a local anesthetic.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
