Subjects were randomized through central registration to be administered LVFX 500 mg once daily or CTRX 1 g twice daily as an intravenous infusion for 7 to 14 days. Clinical efficacy: At the end of treatment, clinical response was 88.5% (92 104) in LVFX-treated and 88.8% (79 89) in CTRX-treated. The intergroup difference was -0.3% (95% confidence interval, -9.3 to 8.7) and non-inferiority of LVFX versus CTRX was established. Microbiologic efficacy: Eradication at the end of treatment was achieved in 96.7% (59 61) treated with LVFX and 97.8% (44 45) treated with CTRX. The intergroup difference was -1.1% (95% confidence interval, -7.3 to 5.1). Safety: Adverse drug reactions were reported in 53.7% (73 136) treated with LVFX and 56.9% (70 123) treated with CTRX. The intergroup difference was -3.2% (95% confidence interval, -15.4 to 8.9). Our results showed that intravenous LVFX 500 mg once daily is as effective and safe as CTRX 1 g twice daily in treating community-acquired bacterial pneumonia., 日本化学療法学会雑誌, 59(S-1), pp.32-45; 2011}, pages = {32--45}, title = {市中肺炎におけるlevofloxacin注射剤のceftriaxone sodiumを対照とした第III相比較試験}, volume = {59}, year = {2011} }
