Mechanism of action

The ingredient blocks pancreatic and gastric lipases. They are the enzymes that crash triglycerides in alvine. When the activity of enzyme is stopped, triglycerides that appear from your dieting can not be hydrolyzed into fatty acids that can be absorbed. They just go out with excretions. But systematically the organism absorbs small amounts of orlistat. After you took a pill for the fist time, the local lipase is inhibited in the limits of the digestive tract. First trace of these discharges is by excrements.

The dietary fat is prevented to be absorbed only by 30% if you take a 120 mg pill before food intake three times a day. As for the nonprescription 60 mg dose, it is only 25%. It will not give any effect if you take a higher dose.


History

Orlistat formula
Orlistat formula
 
It became very popular in the late 20s to use Gull's disease medication for loosing weight. Amphetamine started to be popular in 30s to use for loosing weight. They increased activity, and reduced appetite by pressing people to act more energetic and move loosing calories. When the time was passing by, and the 60s began, people started to mix these stimulants with laxatives, barbiturates and thyroid hormones. It was proved that these pills help to lose weight but at the same time, they bring difficult risks for health and life.

FDA approved Phentermine in 1959. Nowadays on the market it is still the main medicine for weight loss. As the time passed, the new tablets for diet started to appear on the market.

But in February 2007, Orlistat, Xenical's active ingredient was approved by FDA as a drug sold by prescription for treating obesity. The original formulation of Orlistat was produced by ClaxoSmithKline with a brand Alli.

Generic Xenical is an over the counter drug that you can by in the internet. Orlistat was the primary sanctioned by U.S. government medicine that could be sold with no prescription.

Generic Xenical is world-wide popular on the market of diet pills, even if it is some years old. Most of the loosing weight tablets are restraining your appetite, but Orlistat is a blocker of lipase. It stops the digestion of fats that you eat, so they are not absorbed by your body.

GlaxoSmithKline is a manufacturer of Xenical. Xenical does not have any generic versions in America.

December, 2009 was the due date of Xenical's first patent. This explains the non existence of generic version of the medicine. We are assuming that the other patents for Xenical protect the drug from the generic competition, because some of them are due to July 2018.

With a huge number of patents that are listed, it becomes difficult to understand which from the list of patents protects the drug from generic competition. Still no one can make a forecast of the date when there will be a generic version of the medicine.

Orsoten is an orlistat that is available in Russia. In India, they produce generic Orlistat. The brands are Orlica, Olistat, Reeshape and Obelit.

I adore to eat delicious food and I just can’t stop (I am such type of girls). So I decided to use this drug. From everybody I have heard that it works. The results are splendid. I lost 18 pounds in two weeks (my weight was 178 pounds). And what is more important I eat everything I want. Good that I don’t have any side effects, maybe because I don’t pay much attention on them.
