Nephrotoxicity is a dose-limiting side effect of cisplatin (CSP). The study investigated the possible protective role of trimetazidine (TMZ) against CSP-induced nephrotoxicity in rats. Rats were divided into four groups; control, TMZ, CSP, and CSP + TMZ. The CSP group showed significant deterioration in kidney function with structural changes in the form of interstitial hemorrhage, glomeruli shrinkage and peritublar capillary congestion, tubular cells vacuolation, pyknosis, shedding and necrosis, and inflammatory cell infiltrates, all indicating renal damage. CSP also caused a significant increase in the lipid peroxidation marker malondialdehyde (MDA) levels, renal nuclear factor kappa B (NF-κB) DNA-binding activity and protein expression, and tumor necrosis factor alpha (TNF-α) and IL-6 levels. Treatment with TMZ before and after CSP injection produced significant improvement of kidney function and histopathology. TMZ treatment also significantly attenuated CSP-induced oxidative stress and suppressed elevated levels of TNF-α and IL-6 and NF-κB expression and its DNA-binding activity caused by CSP administration. TMZ has a protective effect against CSP-induced nephrotoxicity mediated by reduction of oxidative stress and attenuation of CSP-induced inflammation.
