Description

Application

Orlistat has been used as an inhibitor:
• of fatty acid synthase in long-term estrogen-deprived (LTED) variant cell lines
• of lipase in screening lipase inhibition by raspberry extract
• in in vitro pancreatic lipase activity assay

Packaging

25, 100 mg in glass bottle

Biochem/physiol Actions

Orlistat impairs intestinal fat absorption and is effective in weight management. It is regarded as a safe drug for treating obesity. It delays the progression of type 2 diabetes mellitus especially in obese and improves glycemic parameters. Long term usage of orlistat results in improved weight reduction and it may not contribute in colorectal carcinogenesis.

Orlistat, used in obesity research, is a pancreatic lipase inhibitor that acts locally in the gastrointestinal tract to inhibit lipase.
