Comparison

Exenatide vs Tirzepatide

Function

While Exenatide is used for type 2 diabetes treatment to improve glycemic control and modestly reduce body weight through GLP-1–like insulinotropic and glucagonostatic effects6768, Tirzepatide is approved for type 2 diabetes and obesity, producing larger HbA1c and body-weight reductions than semaglutide in head-to-head trials24.

Mechanism

While Exenatide works as a 39-amino-acid exendin-4 peptide originally isolated from Gila monster venom that acts as a long-acting GLP-1 receptor agonist resistant to DPP-4 degradation67, Tirzepatide is a 39-amino-acid synthetic peptide primarily based on GIP sequence with C20 fatty diacid conjugation that acts as a dual agonist at GIP and GLP-1 receptors, enhancing glucose-dependent insulin secretion, suppressing glucagon, delaying gastric emptying, and reducing appetite24.

Length and Sequence

Exenatide is 39 amino acids long, whereas Tirzepatide is the same length as it has a length of 39 amino acids. Exenatide is made up of a sequence of sequence data not available in the current dataset. Tirzepatide is made up of a sequence of sequence data not available in the current dataset.

Receptor

Exenatide
