加替沙星片与左氧氟沙星片治疗轻中度急性下呼吸道感染的临床疗效比较

目的 :比较加替沙星片与左氧氟沙星片治疗轻、中度急性下呼吸道感染的有效性和安全性。方法 :经临床确诊的轻、中度急性下呼吸道感染患者39例 ,其中加替沙星组 2 0例 ,口服加替沙星片0 .2g ,2次 d ;左氧氟沙星组 19例 ,口服左氧氟沙星片 0 .2g ,2次 d ,疗程均为 5～ 10d。结果 :加替沙星组和左氧氟沙星组痊愈率分别为 75 % (14 2 0 )和73.7% (14 19) ,有效率分别为 95 %和 94 .7% (P >0 .0 5 ) ,两组细菌清除率分别为 10 0 %和 90 % (P >0 .0 5 )。两组间临床和细菌学疗效差异无显著性。两组不良事件发生率分别为 10 .0 %和 10 .5 % ,主要为消化道反应。加替沙星组有 4例 (2 0 .0 % )、左氧氟沙星组有 5例 (2 6 .3% )出现谷丙转氨酶的轻度升高 ,但不影响治疗。结论 :加替沙星片能安全有效地治疗轻、中度急性下呼吸道感染。

Comparison of efficacy and safety between gatifloxacin and levofloxacin in treatment of patients with light to moderate acute lower respiratory tract infections

AIM: To compare efficacy and safety of gatifloxacin and levofloxacin by a randomized controlled trial in treatment of patients with light to moderate acute lower respiratory tract infections. METHODS: 39 cases were assigned to two groups: 20 in gatifloxacin group and 19 in levofloxacin group. The dose of gatifloxacin was 0.2 g per tablet, po, two times a day and the same to levofloxacin. The course of treatment was 5-10 d. RESULTS: The clinical curative rates of gatifloxacin and levofloxacin groups were 75% (14/20) and 63.16 % ( 12/19 ), the effective rates were 100% and 90% (P> 0.05 ), bacterial clearance were 100% and 90%, and adverse reaction rates were 10%(2/20)and 10.53 % ( 2/19 ), respectively. All those adverse reactions were mainly gastrointestinal tract reactions. The abnormality of laboratory inspections associated with trial drugs happened to 4 and 5 patients in two groups. The reactions were mostly light increase of aminotransferase without effect on therapy. CONCLUSION: Gatifloxacin is an antibiotic with large antimicrobial spectrum and can be recommended to treat light to moderate acute lower respiratory tract infections.
