exenatide and sitagliptin

AstraZeneca · FDA-approved active Small molecule

This combination drug stimulates insulin secretion through two complementary pathways: exenatide activates GLP-1 receptors to enhance glucose-dependent insulin release, while sitagliptin inhibits DPP-4 to prolong the action of endogenous GLP-1 and GIP.

Mechanism of action

Exenatide is a GLP-1 receptor agonist that mimics glucagon-like peptide-1, promoting insulin secretion in response to elevated blood glucose and slowing gastric emptying. Sitagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor that prevents the degradation of endogenous incretin hormones (GLP-1 and GIP), thereby extending their glucose-lowering effects. Together, they provide synergistic glycemic control in type 2 diabetes.
