    Abstract:
    Cefepime (BMY-28142), a new semisynthetic cephalosporin, was evaluated for in vitro and in vivo antibacterial activities in comparison with ceftazidime, cefuzonam, cefotaxime and cefmenoxime. Cefepime showed a well-balanced, broad spectrum of activity against a number of clinical isolates collected in Japan. The activity of cefepime against Gram-positive bacteria was several times greater than that of ceftazidime, nearly comparable to cefotaxime and cefmenoxime, and slightly weaker than cefuzonam. Against Enterobacteriaceae, cefepime showed superior activity to the reference cephalosporins against Proteus inconstans, Providencia rettgeri, Morganella morganii, Citrobacter freundii and Enterobacter cloacae. The activity of cefepime against Pseudomonas aeruginosa was nearly comparable to that of ceftazidime. Cefotaxime, cefuzonam and cefmenoxime were substantially less active against P. aeruginosa. Cefepime was more stable than cefuzonam, cefotaxime and cefmenoxime to various types of beta-lactamases from Gram-negative bacteria. The high in vitro activity of cefepime was reflected in its in vivo efficacy against experimental infections in normal and immuno-suppressed mice. Cefepime was the most effective among the cephalosporins tested against four Gram-negative bacterial infections.
