What is orlistate?
Orlistat is a lipase inhibitor that reduces the absorption of fat from the food in the intestine. Approximately 30% of the food fat is taken up unadjusted instead.
Orlistat is available in two dosages:
- 120 mg (receptible, as xenical or generic)
- 60 mg (free of prescription, as Alli or Orlistat Hexal)
It is one of the oldest drugs for weight reduction and works differently than the new GLP-1 agonists: not on the brain, but in the intestine.
