PeptideCompareExenatide — EU research guide.
Exenatide is the original GLP-1 receptor agonist, derived from a peptide found in Gila monster venom — the foundation compound that opened the entire incretin drug class now led by semaglutide and tirzepatide.
What is Exenatide?
Exenatide is a synthetic version of exendin-4, a GLP-1-receptor-activating peptide first isolated from Gila monster saliva. It slows gastric emptying, boosts glucose-dependent insulin release and reduces appetite, administered as Byetta (twice-daily) or Bydureon (once-weekly extended-release).
What does the research show?
Approved by the FDA in 2005 and the EMA shortly after, exenatide has decades of outcomes data in type 2 diabetes, including the EXSCEL cardiovascular-safety trial. Its weight-loss effect is modest compared with newer analogues, which is why it has been largely superseded by liraglutide, semaglutide and tirzepatide.
EU legal status
EMA-approved prescription medicine for type 2 diabetes; also available as a research-grade peptide from RUO suppliers.
