Abstract

The effects of differences in the rate and composition of intravenous fluid replacement for urine loss on the pharmacokinetics and pharmacodynamics of torasemide were evaluated using rabbits as the animal model. Each rabbit received 2-h constant intravenous infusion of 1 mg/kg ∼ 1 of torasemide with 0% replacement (treatment I, n = 6), 50% replacement (treatment II, n = 9), and 100% replacement with lactated Ringer's solution (treatment III, n = 8) as well as with 100% replacement with 5% dextrose in water(D-5-W, treatment IV, n=6).
