Ferulic acid is a kind of phenolic compound that can be found in various fruits and vegetables. This study aims to investigate the effect of ferulic acid on nephrotoxicity induced by gentamicin (GM). In this study, rats were separated into 4 groups such that each containing 8 randomly selected rats: Control group, Ferulic Acid (FA) group, Gentamicin (GM) group and Gentamicin + Ferulic acid (GM + FA) group. Blood samples were collected after 24 hours following the 8-day trial period, and kidneys were taken out for histopathological evaluation. Serum urea, creatinine, uric acid and LDH analyses were performed in autoanalyzer while Malondialdehyde (MDA), Advanced Oxidized Protein Products (AOPP), Glutathione (GSH), Superoxide dismutase (SOD), Catalase (CAT), Interleukin 6 (IL-6), Tumor Necrosis Factor-alpha (TNF-alpha) analyses were performed in ELISA, and kidney tissues were also examined histopathologically. Urea (p < .001), creatinine (p < .001), MDA (p < .01), AOPP (p < .001), IL-6 (p < .01) and TNF-alpha (p < .001) levels were found to be statistically and significantly lowered in GM + FA group when compared to GM group. As a result, ferulic acid has reduced the inflammation in nephrotoxicity induced by GM, causing decreased oxidative stress. In this study, anti-inflammatory features of ferulic acid have come to the forefront rather than the antioxidant features. It can be said that ferulic acid reduces nephrotoxic damage and has protective properties for kidneys.
