Abstract:
Tirzepatide is a unimolecular dual agonist of both glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, which is developed as once-weekly injection for the treatment of type 2 diabetes. Because of the complementarity of action of the two incretins, tirzepatide showed, in a dose-dependent manner (5, 10 and 15 mg), a better efficacy (greater reduction in HbA1c and body weight) compared with placebo, basal insulin and two GLP-1 analogues (dulaglutide and semaglutide) in the SURPASS program. Its cardiovascular protection (versus dulaglutide) is currently tested in SURPASS-CVOT. Finally, studies for the treatment of obesity and metabolic associated fatty liver disease are also ongoing. Gastrointestinal tolerance of tirzepatide appears comparable to that of GLP-1 analogues, except more diarrhoea.

GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...
