Abstract

The pharmacokinetic profile of teicoplanin, a new glycopeptide antibiotic active against Gram-positive aerobic and anaerobic bacteria, is described in five patients with end-stage renal disease on continuous ambulatory peritoneal dialysis (CAPD). A single 3 mg kg-1 dose was given intraperitoneally in the dialysate during a 6 h dwell time. The drug appeared in the plasma within 15 min at 1.00-0.28 mg l-1 (mean ± s.d. = 0.70 ± 0.45) in all five subjects, and peak serum concentrations ranged from 5.53 to 2.80 mg l-1 (4.84 ± 1.43) at 6 h. Approximately 70% (71 ± 12) of teicoplanin was absorbed from the peritoneal dialysis fluid during a single 6 h dwell time. The rate constant for peritoneal transfer (λ(d)) averaged 0.318 h-1 and the half-life (t( 1/2 )λ(d)) was 2.18 h. Further values were serum elimination half-life 114-173 h; total body clearance 263-532 ml h-1; steady-state volume of distribution 68-93 l. This drug profile closely agrees with data reported after intravenous injection in patients on CAPD and suggests that teicoplanin has bidirectional exchange characteristics through the peritoneal membrane, although transfer from the systemic circulation to peritoneal fluid is consistently low. Instillation of teicoplanin in CAPD fluid may be a useful route of administration for treatment of peritonitis and exit site infections in CAPD patients.
