Elimination and haemodynamic effects of nitrendipine in patients with chronic renal failure

In sixteen patients with arterial hypertension and differing degrees of renal function the pharmacokinetics and haemodynamic effects of nitrendipine have been studied after treatment for 7 days. The AUC (0-24) and the elimination half-life of nitrendipine were significantly increased; the AUC (0-24) in patients with renal failure (median creatinine clearance 27.1 ml x min-1) was 196 ng x ml-1 x h compared to 97.8 ng x ml-1 x h in control subjects (median creatinine clearance 94.4 ml x min-1). The corresponding elimination half-lives were 13.5 h in renal failure and 4.4 h in the controls. The haemodynamic effects of nitrendipine were not enhanced in the patients.
