Tirzepatide

fda approvedhuman trialmeta analysis

A dual GIP/GLP-1 receptor agonist that has shown even greater efficacy than semaglutide for weight loss and glycemic control. Tirzepatide represents the next generation of incretin-based therapies, simultaneously targeting two key metabolic pathways.

Dual agonist that activates both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptors. This dual action enhances insulin secretion, suppresses glucagon, slows gastric emptying, and reduces appetite through complementary central and peripheral mechanisms.
