Used primarily as a weight-loss agent, it works by inhibiting pancreatic and gastric lipases, enzymes that break down dietary fats in the intestine. By blocking fat digestion, approximately 30% of ingested fat is not absorbed and is excreted unchanged in the feces. This mechanism helps reduce caloric intake, supporting weight management in obese or overweight individuals. It is commonly used in conjunction with a reduced-calorie diet and is also prescribed to manage metabolic complications associated with obesity, such as insulin resistance and elevated lipid levels. Additionally, due to its effect on fat absorption, it may be used to treat steatorrhea in patients with conditions like cystic fibrosis or chronic pancreatitis.
