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.
