Exenatide
The first approved GLP-1 receptor agonist — a twice-daily injection that improves blood sugar and supports weight loss.
Plain English
Patient-Friendly Explanation
Exenatide, is a twice-daily injection that helps control blood sugar and supports weight loss. It was the first medication in the GLP-1 receptor agonist class — the same family as more recent drugs in this class. It works by helping your body release insulin after meals, slowing stomach emptying, and reducing appetite.
Medical
Clinical Definition
Exenatide is a synthetic form of exendin-4, a 39-amino-acid peptide originally isolated from the saliva of the Gila monster lizard, and acts as a GLP-1 receptor agonist with 53% sequence homology to human GLP-1. It binds to GLP-1 receptors on pancreatic beta cells to enhance glucose-dependent insulin secretion, suppresses inappropriate glucagon release, slows gastric emptying, and activates anorexigenic pathways in the hypothalamus. The twice-daily formulation was the first GLP-1 receptor agonist approved by the FDA (2005) for type 2 diabetes, with weight loss as a demonstrated secondary benefit.
