Haemodialysis does not affect the pharmacokinetics of nifedipine. 1985

H Martre, and R Sari, and A M Taburet, and C Jacobs, and E Singlas

To establish dosage recommendations in patients with end-stage renal disease undergoing chronic haemodialysis, nifedipine kinetics were studied between and during haemodialysis sessions. In eight patients, during the interdialytic period, peak plasma concentrations of nifedipine (29-332 ng/ml) were reached 0.5-1.0 h after administration of a single 10 mg oral dose. Elimination half-life and oral plasma clearance were respectively 2.6 +/- 0.5 h and 1 176 +/- 412 ml/min. Nifedipine plasma protein binding was decreased in uraemic patients (88.8 +/- 0.3% vs 94.4 +/- 0.1%) but not affected by haemodialysis. Removal by haemodialysis was low: the dialyser extraction ratio and the dialysis clearance were respectively 2.3 +/- 0.8% and 2.8 +/- 0.9 ml/min.
