Xenical orlistat is a prescription weight loss pill designed to help people with obesity. Xenical is manufactured by Roche and has been approved for use within the UK since 1998. Unlike weight-loss pills that act in the brain or central nervous system to suppress appetite or to speed up metabolism, Xenical works in your digestive system to block about one-third of the fat in the food you eat from being digested.

How does Xenical orlistat work?
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 (or break down) fat. When taken with meals, Xenical attaches to the lipases and blocks them from breaking down some of the fat you have eaten.
The undigested fat cannot be absorbed and is eliminated in your bowel movements. By working this way, Xenical helps block about one-third of the fat in the foods you eat from being absorbed by your body.
