Cardiovascular effects of tirzepatide.
Abstract
Tirzepatide is a first-in-class dual agonist at receptors for glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) for the treatment of T2D and obesity, with unprecedented efficacy for glycaemic control, reductions in body weight and improvements in blood pressure and lipid profile compared with placebo and GLP-1 receptor agonists. To date, clinical trials of tirzepatide have fulfilled the requirement by regulatory authorities of demonstrated cardiovascular safety in high-risk patients. Whether cardiovascular benefits will be found with dual GLP-1/GIP receptor agonists remains uncertain, and the contribution of GIP receptor activation to cardiovascular risk has not been established. Several ongoing large-scale cardiovascular outcome trials for tirzepatide will provide a clearer understanding of where tirzepatide should be positioned in the treatment of established atherosclerotic cardiovascular disease or in people at high risk, in relation to current standard-of-care cardioprotective agents and approaches.
pepmg summarizes the peer-reviewed literature and links to every source. It sells nothing and ships nothing. Where an FDA label, a peer-reviewed study or a clinical-trial registry entry (labeled trial registry, not peer-reviewed) has published a dose, pepmg reports it with the source named; it gives no personalized recommendations and no administration technique. Don't just trust this summary: follow the citation to its source and read it yourself. Research use only.
