Xenical (orlistat) is a tried and tested obesity treatment that works for most people provided they combine its use with conventional weight loss methods such as diet and exercise. It has received FDA approval after being widely tested for safety and effectiveness. Unlike other medicines that stimulate the brain to suppress your appetite, orlistat differs in its mode of action; this drug works in the digestive tract. As a result, about 30% of your ingested dietary fats pass through your body undigested.

Xenical – Mechanism of Action

Xenical has a unique mechanism of action; it interferes with lipases, the digestive enzymes present in the gastrointestinal tract, by forming covalent bonds with them; this action essentially stops the enzymes in their tracks and so these enzymes become unavailable to break down the dietary fat into absorbable material. This action of orlistat allows for 30% of the dietary fat to pass through your digestive system undigested. This undigested fat is removed from the body through bowel movements.

Benefits of Taking Orlistat

Studies conducted on orlistat have shown that even a modest weight loss can significantly reduce certain life-risk factors. Some of the key benefits of this drug include:

• Decreased risk of diabetes
• Lowered blood pressure
• Reduced blood cholesterol levels
• Reduced uric acid levels in the blood
• Lowered chances of sleep apnea
• Improved appearance, with a positive impact on self-esteem and motivation

Duration of Orlistat Treatment

Orlistat slimming pills have been projected as an effective obesity treatment that can continue long term provided you make consistent weight loss efforts with this drug. About 97% of orlistat, present in Xenical, is known to be excreted in the feces, 83% of which remains chemically unchanged. However, this weight loss medication should not be used over two years because its efficacy beyond that period has not been studied.
