The effects of Nva2-cyclosporine on glomerular filtration and renal blood flow in rats were studied and compared with those of cyclosporine. An infusion of Nva2-cyclosporine (20 mg/kg) caused a 53% fall in glomerular filtration rate (1.0 ± 0.08 to 0.47 ± 0.09; P<0.001) and renal plasma flow (3.2 ± 0.4 to 1.6 ± 0.4; P<0.005). Nvaz-cyclosporine when infused in a dose of 10 mg/kg caused a nearly identical fall in inulin clearance and renal plasma flow. By comparison an infusion of cyclosporine (20 mg/kg) caused a 50% decrease in inulin clearance and a fall in renal plasma flow from 2.6 ± 0.3 to 0.9 ± 0.3. Nva2-cyclosporine or cyclosporine was given chronically in a dose of 20 mg/kg intraperito-neally for seven days. Cyclosporine produced a 27% fall in creatinine clearance, whereas Nva2-cyclosporine produced a 19% decrease in creatinine clearance (NS). These studies suggest that Nva2-cyclosporine has adverse effects on renal blood flow and glomerular filtration rate similar to those seen with cyclosporine.
