Abstract
Cyclophosphamide (CP) is a widely used anticancer and immunosuppressant drug. Nevertheless, clinical utilization of CP is limited due to considerable adverse effects and toxicities. Nicotinamide (NMD) is a micronutrient and the effect of NMD against CP-induced hepatotoxicity is yet unexplored. The present study was designed to evaluate the chemoprotective effect of NMD against CP-induced hepatic injury in Sprague-Dawley rats. Hepatotoxicity was induced by the administration of CP (30 mg/kg/day) for 10 consecutive days by intraperitoneal injection. The chemoprotective effect of NMD treatment (200 mg/kg) against CP-induced hepatotoxicity was evaluated by the oxidative stress, liver function, histopathological changes, and DNA damage. NMD cotreatment significantly reduced CP-induced oxidative stress, histological changes, and apoptosis in the liver. The present study demonstrated that NMD treatment ameliorated CP-induced hepatic damage by improving the antioxidant system and reducing DNA damage. The present findings revealed that NMD supplementation might be useful to reduce CP-associated hepatotoxicity, and thereby can increase the therapeutic utility of CP.
