Dual Incretin Signaling# GLP-1R activation : Enhances glucose-dependent insulin secretion, suppresses glucagon, slows gastric emptying, reduces appetite via hypothalamic signaling GIPR activation : Potentiates insulin secretion, may improve lipid metabolism and fat distribution, enhances central appetite regulation Synergistic effects : The combination produces greater glycemic and weight effects than either pathway alone Pharmacokinetics# The C20 fatty diacid modification enables albumin binding, yielding a half-life of approximately 5 days and supporting once-weekly administration
