Effect of platelet-activating factor antagonist BN 52063 on the nephrotoxicity of cisplatin.

Cisplatin (DDP) is an effective anticancer agent that has been successfully applied against various solid tumors. However, DDP commonly causes nephrotoxicity. We observed that DDP led to significant alterations in renal microcirculation when administered to Munich-Wistar rats, with a concomitant decrease in single nephron glomerular filtration rate due to reduction in glomerular plasma flow and transcapillary hydraulic pressure difference. BN 52063, a platelet-activating factor antagonist, caused a striking change in acute renal failure induced by DDP leading toward normalization of all parameters of renal function. The results suggest that BN 52063 could be used as a novel drug to control DDP nephrotoxicity.
