OBJECTIVE: In the present study, the protective effects of adenosine triphosphate (ATP), Benidipine, and Lacidipine on potential kidney damage induced by 5-fluorouracil (5-FU) were investigated in rats.

MATERIALS AND METHODS: Totally 48 rats were divided into 8 groups: healthy (HG), 5-FU (FUG), ATP+5-FU (AFU), Benidipine+5-FU (BFU), Lacidipine+5-FU (LFU), ATP+Benidipine+5-FU (ABFU), ATP+Lacidipine+5-FU (ALFU) and Benidipine+Lacidipine+5-FU (BLFU). In a 10-day period, ATP (4 mg/kg) was administered intraperitoneally, and Benidipine (4 mg/kg) and Lacidipine (4 mg/kg) were administered orally once a day. On days 1, 3, and 5, 5-FU (100 mg/kg) was administered intraperitoneally one hour after the drug was administered. Afterward, the rats were euthanized, and kidney tissues were removed. An analysis of malondialdehyde, total glutathione, superoxide dismutase, and catalase was performed on tissues, as well as a histopathological examination. A creatinine and blood urea nitrogen analysis were performed on blood samples.

RESULTS: It was revealed that 5-FU decreased the amount of total glutathione, superoxide dismutase, and catalase activities in rat kidney tissues and increased malondialdehyde. Further, increased serum creatinine and blood urea nitrogen levels, as well as histopathological examination of kidney tissues, were found in the 5-FU group. ATP+Benidipine and ATP treatments were the most effective in preventing both biochemical and histopathological changes induced by 5-FU. A treatment with Benidipine improved biochemical and histopathologic data, but not to the same extent as a treatment with ATP+Benidipine and ATP. As a result of Lacidipine+ATP combination, 5-FU-induced biochemical changes in kidney tissue were partially inhibited, but the degree of histopathologic damage remained unchanged. Neither Benidipine+Lacidipine nor Lacidipine showed a protective effect on both biochemical changes and histopathologic damage.

CONCLUSIONS: It may be possible to prevent nephrotoxicity by adding ATP + Benidipine or ATP to 5-FU treatment.
