Orlistat use in type 2 diabetes

OBJECTIVE: To review the use of orlistat in type 2 diabetes. DATA SOURCES: A MEDLINE search of the English-language literature (1990-August 2001) was performed using the key terms orlistat, obesity, glucose, and diabetes. DATA EXTRACTION: All articles pertaining to orlistat were considered for inclusion, with emphasis placed on randomized, placebo-controlled, double-blind clinical trials. DATA SYNTHESIS: In April 1999, orlistat was approved by the Food and Drug Administration for the treatment of obesity. Of 13 randomized, placebo-controlled studies, only 2 reported specific data in individuals with type 2 diabetes. Both reported significant weight reduction and improved glycemic control over placebo. CONCLUSIONS: Since weight loss is a difficult goal to achieve in patients with type 2 diabetes, orlistat can be a safe, effective addition to a multidisciplinary approach.
