Mechanism of Action

Mechanism of Action^1-3

Semaglutide is an incretin mimetic that works on the glucagon-like peptide-1 (GLP-1) receptor by binding and activating the GLP-1 receptor. It has 94% sequence homology to human GLP-1. GLP-1 medications regulate glucose metabolism after oral consumption of carbohydrates and fats. The drug increases insulin secretion by glucose-dependent insulin synthesis and in vivo secretion of insulin from pancreatic beta cells in the presence of elevated glucose levels. It also suppresses glucagon secretion, slows gastric emptying, reduces food intake, and promotes beta-cell proliferation.
