**Introduction to Liraglutide**  

**Definition:**  

Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist, used primarily for managing type 2 diabetes and obesity.  

**Function:**  

It mimics the action of the natural GLP-1 hormone, enhancing insulin secretion, suppressing glucagon release, slowing gastric emptying, and promoting satiety. These mechanisms help regulate blood sugar levels and support weight loss.  

**Applications:**  

Liraglutide is widely used for the treatment of type 2 diabetes, either as a monotherapy or in combination with other medications. It is also approved for chronic weight management in adults with obesity or overweight conditions accompanied by weight-related health issues.
