In patients with type 2 diabetes and heart disease, tirzepatide lowers the combined risk of serious heart and kidney events by 16% compared to dulaglutide.
Mechanism
Synthesis from 2 studies
Tirzepatide helps the body control blood sugar better and lose more weight than dulaglutide, which lowers blood pressure and bad fats. These changes make blood vessels healthier and reduce strain on the heart and kidneys, lowering the chance of serious problems like heart attacks and kidney failure.
Most probable mechanism
Tirzepatide helps the body use insulin better and reduces hunger, leading to lower blood sugar, less fat around organs, and better blood pressure and cholesterol. These changes make blood vessels healthier and reduce strain on the heart and kidneys, lowering the chance of heart attacks, strokes, and kidney damage.
Tirzepatide binds to and activates GLP-1 and GIP receptors on pancreatic beta cells
Receptor activation increases glucose-dependent insulin secretion and suppresses glucagon release
Improved glycemic control reduces oxidative stress and endothelial dysfunction in blood vessels
Activation of GLP-1 and GIP receptors in the brain and fat tissue reduces appetite and increases satiety
Weight loss reduces visceral adiposity, systemic inflammation, and abnormal fat-derived signaling molecules
Improved lipid profile and reduced blood pressure decrease atherosclerotic plaque formation and vascular inflammation
Reduced arterial stiffness and improved endothelial function stabilize plaques and enhance blood flow to organs including the kidneys
Lower cardiac workload and improved renal perfusion reduce the risk of myocardial infarction, stroke, and kidney function decline
