The present study was aimed to investigate the antihyperlipidemic and renoprotective potential of valproic acid against N ω -nitro-l arginine methyl ester hydrochloride (l-NAME) induced hypertension in male albino Wistar rats. In hypertensive rats, mean arterial pressure (MAP), kidney weight, levels of oxidative stress markers in tissues were increased. Dyslipidemia was also observed in hypertensive rats. Moreover, enzymatic and nonenzymatic antioxidant network also deregulated in tissues. Valproic acid (VPA) supplementation daily for four weeks brought back all the above parameters to near normal level and showed no toxicity which was established using serum hepatic marker enzyme activities and renal function markers. Moreover the up regulated expression of renin–angiotensin system (RAS) components were also attenuated by VPA treatment. All the above outcomes were confirmed by the histopathological examination. These results suggest that VPA has enough potential to attenuate hypertension, dyslipidemia and renal damage in nitric oxide deficiency induced hypertension.
