Developed for weight management programs for healthcare professionals to use with their patients, Xenical isn’t just a pill but a structured weight loss plan with a medication that helps block fat from absorbing into the body.

The way that the Xenical program works is to aim to help patients set and reach realistic weight goals while modifying their dietary intake and behavior in the long-term. Patients consult with there doctors and develop an individually tailored program to help people achieve their weight loss goals, and maintain weight loss, through healthy eating, physical activity and behaviour modification coupled with the medication.

Roche, the company that created Xenical, offers free patient support programs in approximately 50 countries worldwide helping support people taking Xenical. Data released recently demonstrated that patients enrolled in Xenical programs can significantly improve the levels of weight loss achieved.

Xenical, also known as Orlistat is a lipase inhibitor for obesity management that acts by inhibiting the absorption of dietary fats. Xenical blocks fat from being absorbed into the body and helps the patient lose weight because the fat that was going into their system no longer absorbed.

Chemically Xenical formula make up is (S)-2-formylamino-4-methyl-pentanoic acid (S)-1-[[(2S, 3S)-3-hexyl-4-oxo-2-oxetanyl] methyl]-dodecyl ester. The empirical formula is C 29 H 53 NO 5, and its molecular weight is 495.7. The product is a single diastereomeric molecule that contains four chiral centers, with a negative optical rotation in ethanol at 529 nm. The tablet is a white to off-white crystalline powder that is housed in capsule form

Xenical is a reversible inhibitor of lipases. It exerts its therapeutic activity in the lumen of the stomach and small intestine by forming a covalent bond with the active serine residue site of gastric and pancreatic lipases.  Because of this the inactivated enzymes are thus unavailable to hydrolyze dietary fat into absorbable free fatty acids and monoglycerides. As undigested fats are not absorbed, the result has a positive effect on weight control. Systemic absorption of the drug is therefore not needed for activity. At the recommended therapeutic dose of 120 mg three times a day, Xenical inhibits dietary fat absorption by approximately 30 percent.

There is not a complicated diet in the Xenical programme which is one of the added incentives to using Xenical. The reduced-calorie diet that is recommended with the use of Xenical with no more than 30 percent calories from fat is the same one recommended by the American Heart Association.

The Xenical program doesn't involve a complicated diet. This is one of the added incentives to using Xenical. The reduced-calorie diet that is recommended with the use of Xenical with no more than 30 percent calories from fat is the same one recommended by the American Heart Association for all Americans.
