Liraglutide is primarily used in the management of type 2 diabetes to improve blood sugar control. It works by mimicking the action of the incretin hormone GLP-1, which increases insulin secretion, decreases glucagon release, and slows gastric emptying. This helps to lower blood glucose levels after meals. Additionally, it is prescribed for weight management in adults with obesity or overweight who have at least one weight-related condition, such as hypertension or dyslipidemia. Liraglutide is administered via subcutaneous injection and is often used in combination with diet and exercise for optimal results. It has also shown benefits in reducing the risk of major cardiovascular events in patients with type 2 diabetes and established cardiovascular disease.
