title: Amphotericin B pharmacokinetics in humans.
abstract: The pharmacokinetics of amphotericin B were studied in two patients at the conclusion of long-term therapy for disseminated histoplasmosis. The distribution kinetics of this drug were adequately described by a three-compartment mamillary model with a total distribution volume averaging 4 liters/kg. The elimination phase half-life of amphotericin B was approximately 15 days, reflecting slow release of amphotericin B from a peripheral compartment. In accordance with previous reports, renal excretion accounted for only 3% of total amphotericin B elimination. The pharmacokinetic model for one of the patients also was used to compare the simulated amphotericin B serum levels that would be expected if initial therapy followed two recommended regimens.
