Define Drug Effects on Food Intake - Anorexic Effect?

Have an anorexic effect, either as a direct effect of the drug on appetite e.g., some antibiotics or because of side-effects such as drowsiness or lethargy e.g., tranquilizers. Drugs can suppress appetite, leading to undesired weight changes, nutritional imbalances, and growth retardation. Most central nervous system stimulants, including amphetamine mixture and melhylphenidate, supress appetite or cause frank anorexia.
