Mechanism of ActionLiraglutide has 97% homology to native GLP-1 with modifications for extended half-life. It slows gastric emptying, increases insulin secretion, suppresses glucagon, and acts on brain appetite centers to reduce hunger.Exenatide is a synthetic version of exendin-4 from Gila monster venom. It shares 53% homology with human GLP-1 and resists DPP-4 degradation. Activates GLP-1 receptors to improve glucose control and reduce appetite.

Research SummarySCALE trials showed 5-10% weight loss. LEADER trial demonstrated cardiovascular benefits in diabetics. Extensive long-term safety data available. First GLP-1 approved specifically for weight management (Saxenda).First-in-class GLP-1 agonist with extensive clinical experience since 2005. Studies show 2-4% weight loss and A1C reductions of 0.5-1%. Weekly formulation (Bydureon) provides more consistent levels.

Frequently Asked Questions: Liraglutide vs Exenatide
