Xenical diet pills are indicated for weight loss and weight maintenance when
used in conjunction with a reduced-calorie diet.
Xenical diet pills belong to the class of weight loss drugs that work by
inhibiting fat absorption in the gastrointestinal tract.
Xenical inhibits the enzyme lipase that helps in the absorption of dietary fats
in the stomach and the small intestine. The Xenical diet pills effectively
inactivate the enzyme involved in the digestion of fats.
Xenical interferes with fat digestion, partially blocking the action of lipases,
thus preventing about 30% of the dietary fat from being absorbed. As undigested
fats are not absorbed, the resulting caloric deficit has a positive effect on
weight control. Absorption of the drug is therefore not needed for activity.
Therefore, systemic exposure to Xenical is minimal.
Xenical can disrupt bowel movements, especially if the subject is following a
fatty diet. This creates discomfort, oily spotting, fecal urgency, increased
bowel movements and incontinence, but these symptoms occur only in the beginning
of the treatment.
This drug may decrease your body's absorption of some fat-soluble vitamins. To
ensure adequate nutrition, your doctor may recommend taking a multivitamin that
contains vitamins D, E, K, and beta-carotene. Take your vitamin supplement once
a day, at least 2 hours before or after a dose of orlistat.
