          Abstract

          The effect of lacidipine (LA), a new calcium channel blocker with an antioxidant effect, has been studied on cyclosporine (CsA)-induced nephrotoxicity in male Wistar rats. Lacidipine (1 mg/kg BW) was administered orally 3 days before and 14 days concurrently with CsA (50 mg/kg BW orally). Urine volume, Na<sup>+</sup>, K<sup>+</sup>, Li<sup>+</sup> and creatinine in urine, and blood urea, serum creatinine, lithium, plasma malondialdehyde (MDA) and CsA levels were estimated in blood after 14 days CsA treatment. Kidneys were examined using histological techniques. Blood urea and serum creatinine were increased by 305 and 211%, respectively, with CsA when compared to the saline-treated animals. Creatinine clearance (Ccr) and lithium clearance (Licr) were decreased and proximal tubule fractional reabsorption 1-(Licr/Ccr) was significantly increased with CsA. Lacidipine protected rats from CsA-induced nephrotoxicity. Changes in blood urea, serum creatinine, Ccr, Licr and proximal tubule fractional reabsorption induced by CsA were significantly prevented by LA. There was a 160% rise in MDA levels with CsA, which was significantly reduced equal to control with LA. Histomorphology showed microcalcification with CsA, while it was normal with LA. In rats treated with LA, CsA did not show any microcalcification. Our data suggest that supplementation of LA may be helpful to reduce CsA nephrotoxicity.

            Calcium antagonists and renal protection. Current status and future perspectives.

            During the past decade, considerable attention has been focused on the effects of calcium antagonists on renal function. Direct in vivo and in vitro observations in diverse experimental models indicate that calcium antagonists antagonize preglomerular vasoconstriction. Furthermore, calcium antagonists are postulated to have additional properties that contribute to their ability to afford renal protection. These putative mechanisms include the ability to retard renal growth, and possibly to attenuate mesangial entrapment of macromolecules, and to attenuate the mitogenic effects of diverse growth factors. Although the clinical implications of the above-mentioned findings have not been fully delineated, the results of recent clinical trials indicate that calcium antagonists exert salutary effects on renal function in clinical settings characterized by impaired renal hemodynamics, including transplant-associated acute renal insufficiency and, possibly, cyclosporine nephrotoxicity. Evidence has accrued suggesting that calcium antagonists may also be protective against acute radiocontrast-induced nephrotoxicity. Finally, the renal hemodynamic and natriuretic effects of calcium antagonists commend their use as antihypertensive agents in the management of essential hypertension, renovascular hypertension, and transplant-associated hypertension.
