Difference between Alli and Xenical

FDA has endorsed its approval for Alli diet pill which is the first weight loss drug which is available to an individual without the much needed doctor’s prescription which is mandatory for a number of medicines. Alli helps in fighting the bulge and reducing the occurrence of a number of diseases which are directly linked to obesity. Alli is considered to be quite safe as it works on the digestive tract and is not systemic.

Orlistat is contained in a much higher dosage form which is present in Xenical, whereas it is present in a much lower dose in Alli. Xenical is available with a prescription and for Alli no prescription is required.

Xenical works in the intestines where the fat which is eaten is blocked and comes under the category of lipase inhibitors. There is a decrease of about 30 percent fat which gets absorbed.

Alli works on the enzymes and stops the digestion of fat. Since there is no absorption of fat by the body it is removed in a natural manner through the bowel movements. Alli diet pill does not cause jitters or a palpitated heart, nor does it induce sleeplessness. It has no effect on the brain or the heart.

The fat is also blocked with the help of Xenical, which is removed from the body in the bowel movements. The fat is not stored in the body which in turn inhibits it from being accumulated. With a low calorie intake a positive result is visible on weight loss. The intake of Xenical is advised with each meal which contains fat and the fat contained should not be more than around 30 percent.

Since the drugs have the tendency to block out important fat soluble vitamins from the meals, in order to balance the vitamin intake it is vital to take a multivitamin along with the intake of the pills.
