Fluconazole Pharmacokinetics in Burn Patients

Abstract

ABSTRACT The pharmacokinetics of fluconazole in nine adult patients with severe (30 to 95% total body surface area) burns were studied. There was no significant difference in half-life ( t 1/2 ), clearance (CL), or volume of distribution ( V ) over time in five patients on days 3 and 8 of the study ( P > 0.05). Combined parameter estimates (means ± standard deviations) for all nine patients for the two study periods were as follows: t 1/2 , 24.4 ± 5.8 h; CL, 0.36 ± 0.09 ml/min/kg; and V , 0.72 ± 0.12 liters/kg. These estimates of t 1/2 and CL in burn patients were approximately 13% shorter and 30% more rapid, respectively, than the most extreme estimates reported for other populations.
