摘要
The objective of this study was to compare the efficacy and safety of levofloxacin 750 mg for 5 days versus 500 mg for 7-14 days intravenous (IV) in the treatment of community-acquired pneumonia (CAP). This clinical trial was the first of its kind conducted in Chinese people and also in Asian population. A total of 241 were enrolled and randomized to 750 mg group (n = 121) or 500 mg (n = 120) group from 10 study centers. The median treatment duration was 5.0 days in 750 mg and 9.0 days in 500 mg group. The median total dose was 3750 mg in 750 mg and 4500 mg in 500 mg group. The bacterial eradication rate was 100% in both groups. The overall efficacy rate in 750 mg group was 86.2% (94/109), and 84.7% (94/111), in 500 mg group of full analysis set visit 4, 95% confidence interval of 1.6% (-7.8-10.9%); the statistical results showed that 750 mg group was non-inferior to 500 mg group. The most common clinical adverse drug reactions were injection site adverse reactions in both 750 mg group and 500 mg group; the other common adverse drug reactions were insomnia, nausea, skin rash, etc. The most common drug-related laboratory abnormalities were neutrophil percentage decreased, decreased white blood cell count, alanine aminotransferase, and aspartate aminotransferase elevation in both 750 mg group and 500 mg group. Most of adverse drug reactions were mild in severity and well-tolerated. In summary, the regimen of levofloxacin 750 mg IV for 5 days was at least as effective and well tolerated as 500 mg IV for 7-14 days for the treatment of CAP.
