Tirzepatide in metabolic dysfunction-associated steatotic liver disease and steatohepatitis: a novel star on the horizon?

Metabolic dysfunction-associated steatotic liver disease (MASLD) and its more rapidly progressive variant steatohepatitis (MASH) are widespread chronic liver conditions linked to obesity and other common metabolic disorders. The emergence of tirzepatide, a dual incretin receptor agonist targeting both the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, presents major therapeutic potential for MASLD. This review article explores the mechanisms of action of tirzepatide, highlighting its ability to improve glycemic control, promote weight loss, and potentially ameliorate hepatic steatosis and fibrosis. Recent studies suggest that tirzepatide may offer significant benefits in managing MASLD/MASH by modulating metabolic pathways and enhancing liver health. However, further research is needed to fully understand its long-term impact on MASLD/MASH progression and outcomes across diverse patient populations.
