Pharmaceutical Information
Drug Name Orlistat
Drug ID BADD_D01624
Description The global prevalence of obesity is increasing rapidly. Obesity-related complications lead to significant personal and economic burden by reducing quality of life and increasing the cost of healthcare. In some individuals, diet and exercise are insufficient to maintain weight loss, and pharmacological or surgical intervention is required.[A229928] Orlistat is a lipase inhibitor used in the treatment of obesity that works by inhibiting fat-metabolizing enzymes. It was approved by the FDA for use in combination with a reduced-calorie diet in 1999.[L11130] This drug is a generally well-tolerated and effective weight-loss aid and is now available in both over-the-counter[L31963] and prescription preparations, depending on the dosage quantity.[L11130]
Indications and Usage Orlistat is indicated for obesity management including weight loss and weight maintenance when used in combination with calorie reduction in overweight and obese adults; this indication applies to both the prescription formulation of 120 mg[L11130] and the over the counter formulation of 60 mg.[L31963] Orlistat in the 120 mg prescription formulation is also indicated to reduce the risk for weight regain following weight loss.[L11130]
