This study was undertaken to examine the effect of the major immunosuppressive drug, cyclosporin A (CyA), on endothelial function. Conscious Wistar rats, treated with CyA (25 mg.kg-1 x day-1 im for 15 days), developed an inhibition of the endothelium-dependent acetylcholine (ACh)-mediated vasodilation, diuresis, natriuresis, and guanosine 3',5'-cyclic monophosphate excretion. The response to two endothelium-independent agents, i.e., sodium nitroprusside and atrial natriuretic peptide was preserved in similarly treated rats. The toxic effects of CyA were acutely overcome by the administration of the amino acid L-arginine (L-Arg), a source of substrate for nitric oxide. Moreover, the simultaneous administration of L-Arg (200 mg/kg ip for 15 days) significantly prevented the functional effects of CyA toxicity. The present data suggest that, in early stages of CyA toxicity, the predominant functional alteration occurs at the endothelial level. The reversibility of such alteration by L-Arg opens the possibility for further strategies aimed to reduce the harmful effects of CyA.
