title: Pharmacokinetics of intravenous piperacillin in patients undergoing chronic hemodialysis.
abstract: The pharmacokinetic properties of piperacillin, a piperazine derivative of ampicillin, were determined in seven patients with creatinine clearances less than 7 ml/min who were undergoing chronic, intermittent hemodialysis. A two-compartment linear model was used to analyze the data. Mean elimination half-life was 1.26 +/- 0.1 h; the mean elimination constant was 0.95 +/- 0.08 h-1; the mean volume of distribution was 0.16 +/- 0.02 liters/kg of body weight; the mean volume of the central compartment was 0.10 +/- 0.01 liters/kg of body weight; and the mean clearance was 0.09 +/- 0.01 liters/h per kg of body weight. Mean elimination half-life while off dialysis of 2.1 h.
