title: Concomitant administration of isradipine and spirapril prevents reduction of renal function induced by acute administration of spirapril in patients with reduced renal function.
abstract: Angiotensin-converting enzyme (ACE) inhibitors may cause a further decrease in renal function in patients who already have renal failure. The acute effects of the ACE inhibitor spirapril on renal function were investigated in 10 patients with mild-to-moderate renal failure (serum creatinine of 1.5-2.5 mg/dl). Acute oral administration of spirapril at 6 mg resulted in decreases in inulin clearance (from 53.7 +/- 12.8 to 44.6 +/- 8.8 ml/min; p < 0.02; n = 5) and in PAH clearances (from 215 +/- 141.9 to 184 +/- 37.8 ml/min; p < 0.006; n = 5). However, when the acute administration of 6 mg of spirapril was given concomitantly with isradipine at 5 mg, there were no changes in these renal function parameters.
