Trovafloxacin pneumococcal and staphylococcal postantibiotic effects (PAEs) were 0.7 to 1.8 and 0.7 to 2.4 h, respectively. For Escherichia coli and Pseudomonas aeruginosa, PAEs were 2.4 to 4.4 h. Pneumococcal and staphylococcal postantibiotic sub-MIC effects (PA-SMEs) (0.4 times the MIC) were 2.3 to 3.7 and 2.4 to > 9.2 h, respectively, and E. coli PA-SMEs (0.3 times the MIC) were 6.8 to > 12.0 h. For one P. aeruginosa strain, the PA-SME (0.4 times the MIC) was > 10 h; in the other, rapid bactericidal activity precluded measurement.
