Anti-obesity drug rebate 7 kilos in weeks.

A new anti-obesity drug can reduce a person's weight by more than 7 kilos in twenty weeks if taken in high doses, according to a study published in the journal The Lancet.

That loss was almost three times higher than members of a control group who were administered a placebo and 50 percent more than those who underwent other treatment popular rival, known by the brand Xenical.

The drug in question, called liraglutide, is the first of a new type of anti-obesity agents that mimic the action of a hormone in the digestive system and reduces hunger.

Those who received the highest dose of liraglutide lost an average of 7.2 kilos in twenty weeks compared with the 4.1 kilos lost by patients who were administered orlistat (Xenical) and 2.8 kilos, among those who received placebo.
