Mechanism of Action: GLP-1 receptor agonists work through multiple physiological pathways: Central appetite suppression : These medications cross the blood-brain barrier and activate GLP-1 receptors in the hypothalamus and brainstem, reducing hunger signals and increasing satiety Gastric emptying delay : By slowing stomach emptying, patients experience prolonged fullness after meals Insulin secretion enhancement : Glucose-dependent insulin release improves glycemic control Glucagon suppression : Reduced glucagon secretion decreases hepatic glucose production Tirzepatide offers dual agonism at both GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) receptors, potentially providing enhanced weight loss efficacy compared to single-agonist medications
