The pharmacokinetics of diltiazem were studied in seven patients with chronic renal failure (CRF) not requiring dialysis and in three healthy volunteers after a rapid i.v. infusion of 20mg. Mean plasma concentrations at the end of infusion were 3.15 times higher in patients with CRF than in healthy

✦ Synopsis
The pharmacokinetics of 20 mg torasemide i.v. has been studied in 7 healthy controls and 9 patients with varying degrees of renal impairment. Torasemide had a t1/2 of about 4h which was independent of kidney function, as the nonrenal clearance of torasemide was 3-times greater than its renal clearance. The active metabolite M 1 and the main metabolite M 5 were accumulated in chronic renal failure. In contrast to liver function, therefore, kidney failure does not have an important effect on the pharmacokinetics of torasemide.

The pharmacokinetics of oral diltiazem were studied in 10 patients with chronic renal failure not requiring dialysis and in five healthy volunteers after a single dose of 120mg. We found that patients with chronic renal failure had lower amounts of unchanged diltiazem and of its main metabolite (MA)
