Abstract
The pharmacokinetics and tolerability of a single 8-mg oral dose of rosiglitazone, an anti-diabetic agent, were compared in 10 long-term haemodialysis patients and 10 healthy volunteers. Haemodialysis patients received rosiglitazone 4 h after haemodialysis (non-dialysis day) and 3 h before haemodialysis (dialysis day). Haemodialysis did not influence rosiglitazone pharmacokinetics, and dialytic clearance was low (0.10 l/h). The mean area under the concentration-time curve (AUC(0–∞)), the maximum observed plasma concentration ( Cmax) and the half-life for rosiglitazone were similar in haemodialysis patients (non-dialysis day) and healthy individuals (2192 ± 598 ng.h/ml versus 2388 ± 494 ng.h/ml, 338 ± 114 ng/ml versus 373 ± 95 ng/ml, and 3.70 ± 0.75 h versus 3.81 ± 0.86 h, respectively). AUC(0−∞) and Cmax were not markedly influenced by haemodialysis. Rosiglitazone dose adjustments are not warranted in patients with type 2 diabetes with end-stage renal failure on haemodialysis.
