Orlistat blocks some of the fat that you eat, keeping it from being absorbed by your body. Orlistat is used together with a reduced-calorie diet and weight maintenance to treat obesity in people with certain risk factors (such as diabetes, high blood pressure, and high cholesterol or triglycerides). Orlistat may also be used for purposes not listed in this medication guide. It is dangerous to purchase orlistat on the Internet or from vendors outside of the United States. Medications distributed from Internet sales may contain dangerous ingredients, or may not be distributed by a licensed pharmacy. Samples of "alli" purchased on the Internet have been found to contain sibutramine (Meridia), a prescription weight loss medication that can have dangerous side effects in certain people. For more information, contact the U.S. Food and Drug Administration (FDA) or visit www.fda.gov/buyonlineguide.
Xenical is a drug that is under the brand name of orlistat. Xenical is taken so that it can block some of the fat that you eat, disabling it from being absorbed in the body, thus helping you with the weight loss. It belongs to a drug class that is known as Dietary Fat Absorption Inhibitor.
Xenical is a white to off-white crystalline powder which is insoluble in water, soluble in chloroform, and very soluble in ethanol and methanol. Xenical is available for being administered orally as a turquoise hard-gelatin capsule. Each capsule has a pellet formulation consisting of 120 mg of the active ingredient, orlistat, as well as inactive ingredients such as povidone, sodium starch glycolate, sodium lauryl sulfate and talc.
Xenical is used to aid in weight loss or to reduce the risk of regaining weight that has already been lost. It must be taken together with a reduced-calorie diet.
Xenical works by blocking the enzyme that breaks down fats in your diet. This undigested fat is then removed from the body in bowel movements. Xenical does not hinder the absorption of calories from non-fat foods and sugar, so one still needs to restrict their total intake of calories.
