Cefoxitin disposition during peritoneal dialysis.

AUTOR(ES)
RESUMO

The pharmacokinetic disposition of 2 g of cefoxitin administered intravenously over 30 min was determined in six patients undergoing continuous ambulatory peritoneal dialysis for chronic renal failure. During the 6-h dialysate dwell time after the drug infusion, the mean apparent volume of distribution for cefoxitin was 0.267 liter/kg (range, 0.201 to 0.325 liter/kg), and the mean elimination t1/2 from plasma was 7.8 h (range, 5.5 to 13.1 h). The peritoneal clearance, averaging 1.51 ml/min (range, 0.58 to 2.35 ml/min), was only 7.4% of the mean plasmas clearance of cefoxitin. Cefoxitin clearance was reduced in patients with renal failure and was not increased by peritoneal dialysis.
