FDA Approved
GLP-1 Agonist
Overview

A dual GIP and GLP-1 receptor agonist developed by Eli Lilly. Represents the next generation of incretin-based therapies with potentially superior efficacy to semaglutide for weight loss.

A GLP-1 receptor agonist originally developed for type 2 diabetes, now widely prescribed for weight management. One of the most commercially successful peptide drugs in history.

Mechanism of Action

Activates both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptors, producing enhanced insulin secretion, appetite suppression, and metabolic improvements beyond what single-agonist drugs achieve.

Mimics the incretin hormone GLP-1, stimulating insulin secretion, suppressing glucagon release, slowing gastric emptying, and reducing appetite through central nervous system signaling. The result is improved blood sugar control and significant weight loss.
