Orlistat refers to the saturated derivative of lipstatin, which itself is an effective natural inhibitor of pancreatic lipases isolated from the bacterium Streptomyces toxytricini. Orlistat was however chosen over lipstatin for development as an anti-obesity drug because it is more stable and less complex.

By blocking the activity of lipase, triglycerides from the diet, instead of being hydrolyzed are excreted unchanged. After an oral dose of the drug, only trace amounts of orlistat are absorbed systemically; followed by lipase inhibition within the gastrointestinal tract.

At the standard prescription dose of 120 mg three times daily, before meals, orlistat is capable of preventing the absorption of about 30% of dietary fat. When taking Alli, ensure to combine appropriate diet and exercise. The weight starts to decrease within 2 weeks of initiation of orlistat.
