Currently there are only two anti-obesity drugs available on prescription in the UK; they are Xenical (orlistat) and Reductil (sibutramine). Orlistat is now available over the counter also in the form of Alli weight loss pills. Both Reductil and Xenical work in completely different ways. While Xenical blocks the action of lipase, the enzyme that digests fat in the intestine and stops around 30% of the fat you’ve eaten from being absorbed, Reductil enhances satisfaction by indirectly boosting serotonin levels, a chemical that helps you feel full.
As a result of taking any one of these slimming pills, you can cut down on calorie intake and thus start to lose weight. In fact, Xenical and Reductil are both clinically proven to help people lose weight and therefore these drugs have the support of most health professionals also.
