This short article provides a useful introduction of Xenical, the science behind its effectiveness, the distinctions in between prescription and over-the-counter variations, and the security considerations individuals need to remember.
What is Xenical?
Xenical is a potent, reversible inhibitor of stomach and pancreatic lipases. Unlike lots of other weight loss medications that act upon the central nerve system to suppress cravings or increase metabolism, Xenical works locally within the intestinal tract.
Its main function is to prevent the absorption of dietary fats. When taken with a meal, the active ingredient, Orlistat, connects to the lipase enzymes that normally break down fat particles. Due to the fact that these fats stay undigested, they can not be soaked up by the body and are instead eliminated through defecation.
Secret Characteristics of Xenical:
- Active Ingredient: Orlistat (120mg per capsule).

While both medications consist of Orlistat, the dosage and regulative requirements differ considerably. Xenical contains 120mg of Orlistat and needs a physician's assessment and prescription. Alli, on the other hand, includes 60mg of Orlistat and is available over-the-counter in lots of nations.

When Xenical exists in the stomach and small intestine, it forms a covalent bond with the active site of these lipases. This reaction renders the enzyme not able to hydrolyze dietary fat into an absorbable type.
What Happens to the Unabsorbed Fat?
About one-third of the fat consumed in a meal travels through the system without being digested. This results in a calorie deficit, which adds to weight reduction over time. However, this mechanism likewise requires a strict adherence to a low-fat diet to avoid intestinal negative effects.
