Xenical is a popular prescription drug that is used to treat obese patients. It is also known as tetrahydrolipstatin or Orlistat. It works by preventing the body from absorbing the fats that is taken from one’s diet. In this way, caloric intake is prevented. But this drug can only be used together with a reduced calorie diet that is supervised by a physician.
The substance orlistat is derived from lipstatin, which is known as a natural inhibitor of pancreatic lipases, an enzyme that breaks down triglycerides in the intestine. By inhibiting the function of the said enzyme in the intestine, orlistat prevents the triglycerides or fats from being processed and absorbed by the body. Instead, the fatty acids are excreted from the body undigested. Orlistat is only absorbed in the body in trace amounts. The primary route of the fats is through the feces.
Xenical allows about 30 percent of fat calories that are taken in from one’s diet to go through the intestinal tract undigested and eliminated through the feces. This results in a reduction in weight as fewer fats are being absorbed by the body. Xenical is primarily being prescribed only for obese patients with a body mass index of 30 or more.
What makes Xenical an ideal weight reduction treatment is that it does not affect the brain or the central nervous system. It works mainly in the intestine and the side effects that may be experienced are gastrointestinal-related. Users of the prescribed drug may also experience flatulence as well as stool that may be oily and loose due to the exit of undigested fats. Some people may also experience more frequent bowel movements with a little incidence of some experiencing bowel incontinence.
Xenical is an effective anti-obesity treatment for people with diabetes, high blood pressure or heart disease. It is a relatively safe anti-obesity drug that also provides a long term solution for a person’s weight problems. But the drug, just like any other weight reduction solution, should be combined with a healthy low-fat diet as well as regular exercise in order to provide the best results. People should not try to rely solely on the said anti-obesity drug to lose weight.
And because the drug works with preventing fats from being absorbed by the body in the intestines, users are advised to supplement their body with essential fat soluble vitamins since the normal diet may not be able to provide the necessary amounts due to the effect of the anti-obesity drug. A multivitamin tablet containing the vitamins A, D, E and K as well as beta-carotene should be taken at least two hours before or after taking orlistat.
