glucagon suppression, lowering hepatic glucose output Central Nervous System: Decreases food intake by targeting homeostatic and hedonic appetite pathways (hindbrain/hypothalamus), reducing hunger and cravings, and enhancing satiety Gastrointestinal Tract: Delays gastric emptying, contributing to satiety (transient effect at higher doses) Adiposity/Energy Intake : Weight loss is primarily driven by sustained reduction in caloric intake, not increased energy expenditure Biological Activity Potent GLP-1 receptor agonist Enhances insulin secretion (glucose-dependent) Suppresses glucagon secretion Reduces appetite and caloric intake Produces significant, sustained body weight loss Improves cardiometabolic risk factors (glycemia, blood pressure, lipids) Storage Refrigerate once reconstituted
