Pharmacokinetics of the loop diuretic piretanide in renal failure.

Piretanide 60 mg was administered intravenously over 30 min to 15 men with different degrees of renal failure. The mean piretanide serum concentration at the end of the infusion period was 5.72 +/- 1.51 micrograms/ml. Serum piretanide concentration-time curves declined biexponentially and 24 hours after medication the serum level had fallen to less than twice the detection limit. The terminal half-life ranged from 1.63 to 3.44 h. A relationship to creatinine clearance was not demonstrable. The mean metabolic clearance of piretanide was 107.7 +/- 47.6 ml/min/1.73 m2 body surface area and was the same as that reported for healthy subjects. The renal clearance of piretanide ranged from 3.33 to 43.9 ml/min/1.73 m2 body surface area and very closely correlated with the creatinine clearance (p less than 0.01). Its renal clearance depended principally on active secretion of the drug into the tubule, and glomerular filtration appeared unimportant. There was a close relationship between the amount of piretanide excreted in the urine and the creatinine clearance. Because the diuretic effect of piretanide depends on the concentration of the drug in the tubule, the observed correlation might be of use in evaluating the appropriate dosage of piretanide in patients with renal failure. The present data suggest that single daily doses of piretanide will not result in accumulation, even when high doses are administered to patients with advanced renal failure.
