Effect of acute renal failure on the disposition and elimination of [3H]N-acetyl procainamide ethobromide in the rat.

| Abstract |
The effect of glycerol-induced acute renal failure (ARF) on the disposition and elimination of the organic cation [3H]N-acetyl procainamide ethobromide (APAEB) was investigated in the rat. In rats with ARF the plasma clearance, rate constant for the terminal portion of the plasma concentration-time curve and apparent volume of distribution were all decreased (P less than 0.01). Furthermore, the renal clearance of APAEB and the percentage dose excreted in urine were reduced by 85 and 74%, respectively. Decreased renal excretion probably accounted for the altered kinetics of APAEB in ARF because ligation of the renal pedicles of control rats produced changes in the kinetics of APAEB that were similar to those seen in animals with ARF. No change in either the hepatic content of APAEB or its biliary excretion were detected in rats with ARF. Similarly, the hepatic handling of ouabain and taurocholic acid was previously found to be unaltered in ARF; but by contrast, the hepatic uptake and initial biliary excretion of bromosulphophthalein and indocyanine green were decreased (Bowmer & Yates 1984, Br. J. Pharmacol. 83: 773-782). Together these studies indicate that there is a selective impairment of hepato-biliary transport in ARF.
