What is Exenatide?
Exenatide is a 39-amino-acid peptide based on exendin-4, a naturally occurring peptide found in the saliva of the Gila monster. It shares enough homology with human GLP-1 to activate the GLP-1 receptor but resists rapid DPP-4 degradation, enabling therapeutic glucose-lowering effects.
How does Exenatide work?
Exenatide activates GLP-1 receptors to enhance glucose-dependent insulin release, suppress glucagon, slow gastric emptying, and reduce appetite. Its actions are strongest after meals, helping reduce post-prandial glucose excursions without causing insulin secretion when glucose is low.
Primary Documented Uses
- Adjunctive type 2 diabetes treatment
- Post-prandial glucose control
- Research reference compound for GLP-1 receptor pharmacology
- Historical model for development of longer-acting incretin drugs
Research Summary
Clinical trials show significant A1c reductions and modest weight loss in type 2 diabetes. Exenatide became an important proof-of-concept for the incretin class and helped establish that peptide agonists could improve glycemia while avoiding the weight gain seen with some older diabetes therapies.
Legal and Regulatory Status
Exenatide is FDA-approved as a prescription medication for type 2 diabetes in immediate-release and extended-release formulations. It is not approved as a stand-alone obesity drug.
