Abstract |
The ability of the Ca entry blocker nitrendipine to improve postischemic renal function was studied in nine groups (n = 70) of rats. After anesthesia, nitrendipine was administered for 15 min through the femoral vein. The dose administered depended on the group. Group 1 (n = 7), the control, received only 0.9% NaCl, group 2 (n = 12) 0.25 mg/kg; group 3 (n = 10) 0.50 mg/kg; group 4 (n = 8) 0.75 mg/kg; group 5 (n = 6) 1.00 mg/kg; group 6 (n = 7) 1.50 mg/kg; group 7 (n = 7) 2.00 mg/kg; group 8 (n = 6) 2.50 mg/kg; and group 9 (n = 7) 3.00 mg/kg. After the administration of nitrendipine, the kidneys were rendered ischemic for one hour by cross-clamping the renal vessels. Comparison of 24-h creatinine clearances for 72 h after reversal of ischemia demonstrated that nitrendipine was capable of providing a degree of protection against renal ischemia and the protective effect was dose dependent (p less than .05).
