The other approved anti-fibrotic drug, nintedanib, is a non-specific tyrosine kinase inhibitor, which prevents the phosphorylation multiple targets involved in the development of fibrosis including platelet-derived growth factor receptor (PDGFR), fibroblast growth factor receptor (FGFR), vascular endothelial growth factor receptor (VEGFR) as well as the type II TGF- receptor (105, 106)
Unlike injectable formulations that typically require cold-chain storage, oral GLP-1RAs bypass refrigeration constraints, thereby reducing manufacturing and distribution costs and improving accessibility in resource-limited settings [73]
For translational confidence, studies should include prolonged follow-up (weeks to months), dose-fractionation schedules that mimic chronic dosing, aged animals or disease models, and paired clearance experiments to quantify retention and excretion routes (170)
