SITAGLIPTIN PHOSPHATE Target & Pathway

Pro

Target

GLP-1 (Glucagon-Like Peptide-1) Incretin Receptor

A hormone released after eating that stimulates insulin secretion, suppresses glucagon, slows gastric emptying, and promotes satiety. GLP-1 receptor agonists mimic these effects, improving blood sugar control and promoting weight loss in diabetes and obesity.
