Review on Xenical

Under the trade name Xenical there is a main compound called orlistat, a saturated derivative of lipstatin a potent natural inhibitor of pancreatic lipases isolated from the bacterium Streptomyces toxytricini. It all may sound widely complicated, however it is not - Xenical is a drug designed to treat obesity.

Xenical's primary function is to prevent the absorption of fats from the human diet, thereby reducing caloric intake, recommended only with a physician's supervision. The pill works by inhibiting pancreatic lipase, an enzyme that breaks down triglycerides in the intestine. This enzyme being stopped, triglycerides from the diet are prevented from being hydrolyzed into absorbable free fatty acids and are excreted undigested, they don't stick around to widen the hips or belly.

As Xenical is a pill, on its information sheet we expect to found side effects as well, as we are used to when reading the prospectus of a medication. And guess what, Xenical has them. The primary side effects of the pill are gastrointestinal-related. Due to the fact, that orlistat's main effect is to prevent dietary fat from being absorbed, the fat is excreted unchanged in the feces and so the stool may become oily or loose, while increased flatulence is also common. When using orlistat, the absorption of fat-soluble vitamins and other fat-soluble nutrients is also inhibited, so taking multivitamin tablet containing vitamins A, D, E, K, and beta-carotene is recommended at least 2 hours before or after taking the pill.

For all who decide to try losing fat with Xenical, alleviating is the fact that side effects are most severe when beginning therapy, and decrease in frequency with time. Based on a clinical study, nearly half of side effects lasted less than a week, however cases have been described to persist for over six months.
