In order to evaluate the effect of piretanide on the renal transport of water and osmotic substances, a clearance study was carried out in well hydrated rabbits. After intravenous bolus administration of piretanide, glomerular filtration rate, proximal tubular clearance and urine flow rate, as well as the pharmacokinetics of piretanide, were determined. A pharmacokinetic and pharmacodynamic link model which was developed in the previous paper was applied to the present experimental results. The results indicated that the effect of piretanide on the renal transport of water and osmotic substances in the hydrated rabbits was reasonably described by the model. The model analysis suggested that the diuretic response to piretanide was attributable to the inhibition of reabsorption of electrolytes in the proximal tubule, as well as in the loop of Henle.
