BACKGROUND Amikacin has the largest spectrum among aminoglycosides, its nephrotoxic effect limits its utilization. Our purpose in this study is to review the protective effect of dexpanthenol against the nephrotoxic effect of amikacin, accompanied with histopathological and biochemical parameters. METHODS 32 rats were randomly separated into four groups with eight in each (amikacin (1.2mg/kg/day), amikacin (1.2mg/kg/day)+dexpanthenol (500mg/kg/day), dexpanthenol (500mg/kg/day) and control). In order to assess the oxidative balance and renal damage between groups, biochemical parameters (total antioxidant capacity (TAS), total oxidant stress (TOS), catalase (CAT), paraoxonase (PON), arylesterase (ARES), urea, and creatinin) were studied from the blood samples. At the end of the 14th day, renal tissues were reviewed blindly by a pathologist. RESULTS TOS and oxidative stress index (OSI) values were significantly lower in the group which was administered with dexpanthenol+amikacin compared to the group which only received amikacin (respectively, p=0.001, p=0.002). Antioxidant biochemical parameters (TAS, CAT, PON, and ARES) were significantly higher in the group which was administered with dexpanthenol+amikacin compared to the group administered only with amikacin (respectively, p=0.007, p=0.001, p=0.003, p=0.003). Urea and creatitin values were found to be significantly lower in the group which was administered with dexpanthenol+amikacin compared to the group administered only with amikacin (respectively, p=0.002, p=0.001). Histopathologic changes such as glomerular and tubular epithelium changes and interstitial edema were clearly observed in the group administered only with amikacin, such findings were insignificant in the group administered with dexpanthenol+amikacin. CONCLUSIONS It was revealed with biochemical and histopathologic data that nephrotoxic effects created by amikacin administration can be limited with dexpanthenol by using them together, and further advanced clinical studies are required.
