Effect of diltiazem and captopril on renal pathology in glycerol induced acute renal failure in rats

ABSTRACT

To evaluate the effect of pharmacologic vasodilators on glycerol induced acute renal failure, we studied untreated animals and those given Diltiazem and Captopril at a period of 24 hours 3 days and seven days after the onset of acute renal failure. At each time comparative assessment of renal histology were performed. Diltiazem a calcium channel blocker significantly reduced the extent of tubular cell necrosis and was associated with a more rapid histologic recovery. Captopril, an angiotensin converting enzyme inhibitor, did not influence renal pathology throughout the observation period. Diltiazem was benificial and offered significant protection against glycerol-induced acute renal failure in rats; it may have a protective effect at least in early stages of acute renal failure in humans
