Cagrilintide is a long‑acting amylin analog that reduces appetite via central satiety pathways, while Semaglutide activates GLP‑1 receptors to enhance glucose‑dependent insulin secretion and suppress glucagon[4][5]. The combination leverages complementary mechanisms: amylin primarily delays gastric emptying and signals satiety through the area postrema, while GLP‑1 enhances pancreatic β‑cell function and central appetite suppression[1]. Clinical trials of the co‑administered regimen (CagriSema) show greater body‑weight reduction than either agent alone[2].
