BYETTA

EXENATIDE SYNTHETIC Glucagon-like Peptide-1 (GLP-1) Agonists
Metabolic Approved 2005-04-28

BYETTA (exenatide) is a glucagon-like peptide-1 (GLP-1) receptor agonist indicated to improve glycemic control in adults with type 2 diabetes mellitus. It is used as an adjunct to diet and exercise in this patient population. The medication is not recommended for coadministration with other products containing exenatide. Its therapeutic role is to reduce both fasting and postprandial glucose concentrations.

How BYETTA Works

BYETTA functions by binding to and activating the human GLP-1 receptor, which enhances glucose-dependent insulin synthesis and secretion from pancreatic beta cells. The drug also suppresses inappropriately elevated glucagon secretion and slows the rate of gastric emptying. These combined actions lead to a reduction in blood glucose levels. These effects are mediated through intracellular signaling pathways involving cyclic AMP.

BYETTA 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.
