An anorexiant drug, also known as an appetite suppressant, is a medication that helps reduce or suppress appetite, leading to decreased food intake. It is commonly used as a treatment for obesity or as a part of weight management programs. Anorexiant drugs work by affecting the central nervous system or the body's metabolism, resulting in a decreased sensation of hunger and increased feelings of fullness. These medications are typically prescribed under medical supervision and are intended for short-term use as part of a comprehensive weight loss plan.
