Drugs targeting GLP-1 and GIP receptors for heart protection, type 2 diabetes, and obesity: how they work and clinical findings

Updated

Abstract

Tirzepatide, a first-in-class GLP-1/GIP receptor co-agonist, has shown significant reductions in glycemia and body weight in phase 3 trials for type 2 diabetes.

  • Tirzepatide is currently approved for managing type 2 diabetes and is awaiting approval for obesity management.
  • It has demonstrated superior efficacy in reducing glycemia and body weight compared to GLP-1 receptor mono-agonism with semaglutide.
  • Significant body weight reductions were observed in individuals with obesity, even in those without diabetes.
  • Tirzepatide enhances lipid metabolism, reduces blood pressure, and lowers liver fat content.
  • Pooled phase 2/3 data indicate cardiovascular safety in type 2 diabetes patients.
  • A post hoc analysis suggests that tirzepatide may slow the decline of kidney function in individuals with type 2 diabetes.
