Anorexigenic Drugs for Weight Loss: Types, Side Effects, and Risks

Anorexigenic refers to a substance or agent that suppresses appetite or food intake, leading to weight loss. Anorexigenic drugs are commonly used to treat obesity and related conditions such as metabolic disorders. These drugs work by affecting the brain's reward system, which regulates hunger and satiety, or feelings of fullness.

Examples of anorexigenic drugs include:

1. Amphetamines: These drugs stimulate the central nervous system and increase alertness, leading to a decrease in appetite.
2. Fenfluramine: This drug was previously used as an appetite suppressant but was withdrawn from the market due to its potential to cause heart valve problems.
3. Phentermine: This drug is an appetite suppressant that works by increasing the levels of certain neurotransmitters in the brain, leading to a decrease in hunger.
4. Orlistat: This drug blocks the absorption of dietary fat, leading to weight loss.
5. Liraglutide: This drug is an injectable medication that helps reduce body weight by decreasing hunger and increasing feelings of fullness.

It's important to note that anorexigenic drugs should only be used under the guidance of a healthcare professional and as part of a comprehensive weight loss plan. These drugs can have serious side effects, including increased heart rate and blood pressure, anxiety, and insomnia. Additionally, they may not address the underlying causes of overeating or obesity, and may not lead to long-term weight loss.
