The Basic Information About Orlistat

According to statistics from the World Health Organization (WHO), nearly 2 billion people are overweight or obese worldwide. Every year, overweight or obesity causes 2.8 million deaths.  

What’s Orlistat?

Orlistat is a lipase inhibitor used in the treatment of obesity that works by inhibiting fat-metabolizing enzymes. It was originally approved by the FDA in 1999 as the prescription drug Exenical, was approved in 2007 as the over-the-counter medication Alli. It has been the most commonly used medicine to treat obesity for more than a decade. This drug is a generally well-tolerated and effective weight-loss aid.

What’s the mechanism of action?

Orlistat is a drug designed to treat obesity. It’s a potent and selective inhibitor of various lipase enzymes responsible for the metabolism of fat. It acts in the gastrointestinal (GI) tract via covalent binding to the serine residues located on the active site of both gastric and pancreatic lipase. When orlistat is taken with food containing fat, it partially inhibits the hydrolysis of triglycerides. This decreases absorption of monoaclglycerides and free fatty acids, contributing to weight maintenance and weight loss.
