XENICAL contains the active ingredient orlistat.
XENICAL is to treat people who are overweight or obese.
This medicine is available only with a doctor's prescription.
XENICAL belongs to a group of medicines called lipase inhibitors.
These medicines work by targeting the absorption of dietary fat in your body rather than suppressing your appetite.Dietary fats are large molecules that need to be broken down before they can be absorbed into the body. They are broken down by enzymes called lipases. That is, lipases play an important role in the digestion of dietary fat. When taken with a meal, XENICAL interferes with the activity of these enzymes. This allows about 30% of the fat eaten in the meal to pass through the gut undigested. Therefore, your body cannot store these excess calories as fatty tissue or use them as a source of energy. This helps you to reduce your weight by burning up fat that you are already carrying.
