Effect of Captopril and BQ123 Endothelin-1 Antagonist on Experimentally Induced Hyperlipidemic Nephropathy in Rats.

Background: Kidney disease is a universal public health problem, and epidemiological studies demonstrated that the incidences of chronic kidney disease are increasing day by day. However, the efficiency of currently available drugs on the progression of nephropathy is limited. Therefore, the current research was designed to evaluate the therapeutic efficacy of captopril and BQ123 against hyperlipidemia-induced nephropathy in rats.

Objective: The objective of this study was to examine the implication of Endothelin-1 in experimentally induced hyperlipidemic nephropathy in rats.

Methods: Animals were divided into various groups, and the administration of a high-fat diet for six weeks induced hyperlipidemia. After confirmation of hyperlipidemia, treatment was started for the next 14 days. At the end of the experimental period, the animals were sacrificed, and various biochemical parameters and histopathological studies were performed.

Results: Treatment of both the agents in combination effectively decreased BUN levels, serum creatinine, serum nitrite, and proinflammatory markers and ameliorated the pathological injuries to kidneys.

Conclusion: Furthermore, both treatments also inhibited oxidative stress and restored the hyperlipidemia-induced reduction in the level of antioxidant enzymes.
