What is Exenatide?

Exenatide was the first GLP-1 receptor agonist approved for clinical use. It is a synthetic version of exendin-4, a peptide discovered in the saliva of the Gila monster lizard. It shares 53% homology with human GLP-1 but is resistant to DPP-4 degradation. Available as twice-daily (Byetta) or once-weekly (Bydureon) formulations.

How It Works

Exenatide works like the body's natural GLP-1 hormone but lasts much longer because it comes from a lizard peptide that resists breakdown. It helps control blood sugar and reduces appetite.
