Cetilistat is primarily used as an anti-obesity medication. It works by inhibiting the action of lipase enzymes in the gut, which are responsible for breaking down fats into smaller molecules that can be absorbed by the body. By blocking these enzymes, Cetilistat prevents the absorption of dietary fats, leading to a reduction in calorie intake and aiding in weight loss. This makes it particularly useful for individuals who are overweight or obese and are seeking a pharmacological aid to complement diet and exercise. Additionally, it can be beneficial for managing conditions associated with obesity, such as type 2 diabetes and high cholesterol, by helping to reduce overall body weight and improve metabolic health. It is often prescribed when other weight loss methods have not been effective, and it is typically used under medical supervision to monitor for potential side effects, such as gastrointestinal issues.
