Pharmacokinetics of intraperitoneal and intravenous fosfomycin in automated peritoneal dialysis patients without peritonitis.

ABSTRACT: Blood and dialysate concentrations of fosfomycin were determined after intravenous and intraperitoneal application of 4 mg/liter in patients undergoing automated peritoneal dialysis. Maximum serum concentrations after intravenous (287.75 ± 86.34 mg/liter) and intraperitoneal (205.78 ± 66.78 mg/liter) administration were comparable. Ratios of intraperitoneal to systemic exposure were 1.12 (intraperitoneal administration) and 0.22 (intravenous administration), indicating good systemic exposure after intraperitoneal application but limited penetration of fosfomycin into the peritoneal fluid after the intravenous dose.
