How does it work

This miracle drug does not work on the brain as appetite suppressants do; it limits its activities to the intestines. That is why it is one of the few FDA approved drugs for long term weight management. In the intestines it sets about blocking the absorption of up to 30% of the fat you eat. This undigested fat is eliminated by the bowel.

Xenical will not solve the weight problem on its own despite its miracle qualities. You will need to couple the medication with a balanced calorie reduced diet and, yes, regular exercise. There is no getting away from that. What is wonderful though is that now you have something quite considerable on your side, something that is capable of sifting out some of that nasty fat so that weight loss is pretty much guaranteed.

Mechanism of Action

Xenical is a potent and specific long-acting inhibitor of gastrointestinal lipases . It exerts its therapeutic activity in the lumen of the stomach and small intestine by forming a covalent bond with the serine residue of the active site of gastric and pancreatic lipases. The inactivated enzyme is thus unable to hydrolyse dietary fat, in the form of triglycerides, into absorbable free fatty acids and monoglycerides. As undigested triglycerides are not absorbed, the resulting caloric deficit has a positive effect on the weight control.
