Victoza · Saxenda

Liraglutide is a once-daily GLP-1 receptor agonist approved for type 2 diabetes (Victoza) and obesity (Saxenda). It achieves fatty acid attachment to albumin for extended half-life, enabling daily dosing. The LEADER trial established significant cardiovascular mortality benefit in high-risk patients, and research continues into neuroprotective and anti-inflammatory properties beyond metabolic indications.

Ozempic · Wegovy

Semaglutide is a long-acting GLP-1 receptor agonist approved for type 2 diabetes (Ozempic, Rybelsus) and obesity (Wegovy). By mimicking the incretin hormone GLP-1, it enhances glucose-dependent insulin secretion, suppresses glucagon, slows gastric emptying, and reduces appetite via central hypothalamic pathways. Landmark trials demonstrate up to 15–17% body weight reduction and significant cardiovascular mortality benefit.
