Quinidine pharmacokinetics in continuous ambulatory peritoneal dialysis

The clearance of quinidine was evaluated in a patient undergoing continuous ambulatory peritoneal dialysis (CAPD). The dialysis clearance of quinidine was 0.793 ml/min which represented only 0.61% of the total body clearance (154.21 ml/min) of the drug. The elimination half-life of quinidine was 5.44 hours. Based on our results, dosage adjustment of quinidine does not appear to be necessary for patients undergoing CAPD.
