Bactericidal activity of two different dosage regimens of imipenem in an in-vitro dynamic model.
The antimicrobial activity of imipenem was tested in an in-vitro model mimicking human serum pharmacokinetics after either 1000 mg im once daily or 500 mg im twice daily. Six recent clinical isolates of Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Proteus mirabilis, Klebsiella pneumoniae and Salmonella group B were used as test strains. Our results suggest that a single daily dose of imipenem 1000 mg im exerts an antibacterial action comparable to that obtained with two divided doses of 500 mg.
