Ceftibuten and bactericidal kinetics. Comparative in vitro activity against Enterobacteriaceae producing extended...

Ceftibuten, compared to cefixime, cefetamet, cefpodoxime, loracarbef, cefprozil, cefuroxime, cefaclor, and cefadroxil, was the most active oral cephalosporin derivative against Enterobacteriaceae producing plasmid-encoded broad spectrum beta-lactamases. In a pharmacodynamic model, ceftibuten was bactericidal for Haemophilus influenzae and Streptococcus pneumoniae at concentrations simulating human serum levels following 200 mg, p.o., b.i.d.
