Abstract

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.

摘要

曲伐沙星对肺炎球菌和葡萄球菌的抗生素后效应(PAEs)分别为0.7至1.8小时和0.7至2.4小时。对于大肠杆菌和铜绿假单胞菌,PAEs为2.4至4.4小时。肺炎球菌和葡萄球菌的抗生素后亚抑菌浓度效应(PA - SMEs)(0.4倍MIC)分别为2.3至3.7小时和2.4至>9.2小时,大肠杆菌的PA - SMEs(0.3倍MIC)为6.8至>12.0小时。对于一株铜绿假单胞菌,PA - SMEs(0.4倍MIC)>10小时;另一株则因快速杀菌活性而无法测量。
