Exenatide vs Maridebart cafraglutide
A GLP-1 receptor agonist derived from Gila monster venom (exendin-4). GLP-1 agonism paired with GIP receptor antagonism — the opposite GIP direction to tirzepatide. Side by side: type, evidence tier, receptor, molecular weight, and half-life — the same fields as each monograph, rearranged so the engineering difference is visible.

Common questions
- What is the difference between Exenatide and Maridebart cafraglutide?
- Exenatide is an engineered analog based on Glucagon-like peptide-1; Maridebart cafraglutide is an engineered analog based on Glucagon-like peptide-1. Exenatide signals at GLP-1 receptor (GLP-1R); Maridebart cafraglutide signals at GLP-1 receptor (agonist) + GIP receptor (antagonist).
- How do the half-lives of Exenatide and MariTide compare?
- The reported circulating half-life of Exenatide is ~2.4 h (immediate-release); Maridebart cafraglutide is ~21 days (monthly dosing). These are reference values for the native or representative form — educational only, not dosing advice.
- Is Exenatide the same as Byetta?
- Byetta, Bydureon are brand names of Exenatide. This comparison describes the molecules, not branded products.
