Sibutramine is a medication that was previously used for the management of obesity. It acts as an appetite suppressant and was commonly prescribed to aid weight loss efforts.

Medical Uses

Sibutramine was primarily used for the following medical purpose:

1. Weight Loss: It was prescribed for the management of obesity in individuals who had not achieved sufficient weight loss through diet and exercise alone.

Mechanism of Action

Sibutramine exerts its effects through the following mechanism:

• Appetite Suppression: Sibutramine acts centrally in the brain by inhibiting the reuptake of neurotransmitters such as serotonin, dopamine, and norepinephrine. By increasing the levels of these neurotransmitters in synaptic clefts, it enhances feelings of fullness (satiety) and reduces appetite, leading to decreased food intake.

Side Effects

While effective in promoting weight loss, sibutramine can cause several potential side effects:

1. Cardiovascular Effects: Sibutramine can increase heart rate and blood pressure, which may lead to cardiovascular complications, especially in individuals with pre-existing heart conditions.
2. Central Nervous System Effects: Some users may experience insomnia, headache, dizziness, or anxiety.
3. Gastrointestinal Issues: Sibutramine can cause dry mouth, constipation, or nausea.
