Exenatide
AFDA ApprovedGLP-1 receptor agonist · 39 amino acids · Brand: Byetta, Bydureon BCise
Exenatide is a GLP-1 receptor agonist and the first incretin mimetic approved by the FDA for type 2 diabetes (Byetta, 2005; Bydureon BCise, 2017). Derived from the saliva of the Gila monster (Heloderma suspectum), it was the foundational drug that established the GLP-1 class.
Mechanism of Action
Mimics endogenous GLP-1, binding to GLP-1 receptors to enhance glucose-dependent insulin secretion, suppress glucagon release, slow gastric emptying, and reduce appetite. The twice-daily and once-weekly formulations differ in peptide backbone modifications and microsphere encapsulation.
Benefits
Side Effects
- Nausea and vomiting (common, dose-dependent)
- Diarrhea
- Hypoglycemia risk when combined with sulfonylureas
- Pancreatitis (rare, class warning)
- Anti-exenatide antibodies may develop
