| Summary: | Background: It has been postulated that during liver and kidney damage there is a decreased in the antioxidant status associated with a simultaneous increase in the reactive oxygen species and lipid peroxidation. In consonant with this, Capecitabine, an oral chemotherapy and inactive non-cytotoxic fluoropyrimidine considered for the treatment of advance colorectal cancer, has also been shown to induce oxidative stress in liver tissues. Caffeic acid, a typical hydroxycinnamic, has been claimed to be effective against oxidative stress. Therefore, this present work studied the protective effect of caffeic acid on oxidative stress-induced liver and kidney damage by the administration of capecitabine. Methods: Twenty-four male Wistar strain rats were randomly divided into four treatment groups: A. control, B. capecitabine (CPTB)-treated group (30 mg/kg b.w. CPTB), C. caffeic acid (CFA)-treated group (100 mg/kg b.w. CFA) and D. co-treated group with CFA (100 mg/kg b.w.) and CPTB (30 mg/kg b.w.). Results: Caffeic acid administration significantly ameliorated the elevated plasma biomarkers of hepatic and renal tissue damage induced by the capecitabine and improved enzymatic and non-enzymatic antioxidant levels in liver organ. Conclusions: The protective effect of caffeic acid could be attributed to its ability to boost the antioxidant defence system and reduce lipid peroxidation.
