In order to define a dose regimen of teicoplanin for patients undergoing chronic haemodialysis so that they achieved trough drug serum levels above 10 mg/l, two single doses of 5 and 10 mg/kg were administered intravenously in seven anuric patients immediately after the end of haemodialysis. Concentrations of teicoplanin were determined by a microbiological assay in samples collected from peripheral veins via the arterial and the venous lines of the fistulae and from the dialysate during haemodialysis. The administration of a 5 and 10 mg/kg dose gave mean C(max) of 62.80 and 122.43 mg/l, mean AUC of 526.43 and 1103.98 mg h/l, mean half life (t(1/2)) of 109.09 and 107.06 h, mean clearance rates of 12.85 and 12.44 ml/min, mean apparent volumes of distribution of 1.68 and 1.68 l/kg and mean volumes of distribution at steady state of 0.31 and 0.28 l/kg, respectively. Trough serum levels above 10 mg/l were found for 24 h after the administration of the 5 mg/kg dose and for 48 h after the administration of the 10 mg/kg dose. Teicoplanin was not detected in the dialysate. Its concentrations in both the arterial and the venous lines of the fistulae were similar. Based on the time period after the administration of teicoplanin where the desired trough serum levels were found and on the observed t(1/2), it is proposed that teicoplanin should be administered at a dose of 10 mg/kg at 48-72 h intervals, in patients undergoing chronic haemodialysis for the therapy of infections caused by Gram-positive cocci.
