Drug Informations online - Xenical

Xenical is a gastrointestinal lipase inhibitor used to treat obesity.

If you eat an excessive amount of fat or calories, the excess is stored as fat by the body, resulting in weight gain. When you eat fat, your body breaks it down into its simplest components so that it can be digested.

Enzymes in your digestive system, called lipases, help digest fat. When taken with meals, Xenical attaches to the lipases and blocks them from breaking down some of the fat you have eaten.
