Abstract

A new in vitro model was devised for evaluating the bactericidal activity of antibiotics under dynamic conditions. This model accurately reproduced the observed serum levels of antibiotics after intravenous dosing. The apparatus consists of two vessels which correspond to the central and peripheral compartments of a two-compartment open model. The volume of medium in each vessel and flow rates of media were determined from the pharmacokinetic parameters calculated from the observed serum levels selected for simulation. The bactericidal activity of cefazolin against strains of Escherichia coli and Klebsiella pneumoniae showing different minimal inhibitory concentrations was investigated with the apparatus simulating serum levels after intravenous injection, and the bactericidal activity was evaluated with respect to the relationship between the minimal inhibitory concentration and the serum levels.
