Introduction: Doxorubicin (DOX), a well-known chemotherapeutic drug, has been reported to induce numerous toxic side effects including renal toxicity. This preliminary study was designed to investigate the ameliorative effects of methanolic leaf extract of Clerodendrum volubile (MECV) against DOX-induced nephrotoxicity in rats. Methods: Thirty male rats were divided into five groups; (a) Control group: rats were given 0.9% NaCl as vehicle, (b) DOX group: a single dose of DOX (25 mg/kg; i.p.) was administered and the rats were sacrificed 4 days after DOX injection, (c-e) Methanolic extract of C. volubile (MECV)-treated DOX groups: rats were given MECV (at the doses of 125, 250 and 500 mg/kg/d), respectively for 12 consecutive days, 8 days before and 4 days after the DOX administration.Results: DOX injection caused a significant increase (P < 0.05) in serum creatinine and urea levels. The levels of renal antioxidant parameters: glutathione peroxidase, superoxide dismutase (SOD), catalase (CAT) and reduced glutathione were significantly (P < 0.05) decreased in DOX-intoxicated rats with concomitant elevation of malondialdehyde level. Pretreatment with MECV restored antioxidant status, attenuated oxidative stress and improved kidney function markers. Pre-treatment with MECV protected renal tissues against DOX-induced nephrotoxicity. Conclusion: The ameliorative effects of C. volubile leaves on these renal biochemical parameters may be via its antioxidant action and may serve as a novel combination agent with DOX to limit its renal damage.
