摘要: 目的: 开展吉米沙星对泌尿道常见致病菌的药动学/药效学研究。方法: 测定吉米沙星对临床分离的泌尿道常见致病菌的最小抑菌浓度及最低杀菌浓度;测定健康受试者口服甲磺酸吉米沙星片 320 mg 后尿药浓度并计算Cmax/MIC90和AUC24 h/MIC90结果: 吉米沙星对临床分离的泌尿道常见致病菌的敏感率较低。健康受试者口服甲磺酸吉米沙星片 320 mg 后尿药峰浓度Cmax为(144±124) μg/mL,尿药浓度时间曲线下面积AUC24 h为(1368±671) μg·mL-1·h。尿液中吉米沙星对大肠埃希菌、铜绿假单胞菌、粪肠球菌的Cmax/MIC90为 2.9~5.8、AUC24 h/MIC90>30;对肺炎克雷伯菌、屎肠球菌AUC24 h/MIC90为 19.25。结论: 吉米沙星可有效清除泌尿道感染的大肠埃希菌、铜绿假单胞菌、粪肠球菌,并避免耐药菌产生;对肺炎克雷伯菌、屎肠球菌生长有抑制作用。

Abstract: AIM: To carry out PK/PD study of gemifloxacin mesylate against common pathogenic bacteria in urinary tract.METHODS: MIC (minimum inhibitory concentration) and MBC (minimum bactericidal concentration) of gemifloxacin against common pathogenic bacteria in urinary tract were determined. Urine concentration of healthy subjects after oral administration of gemifloxacin mesylate tablets (320 mg) was determined and then Cmax/MIC90 and AUC24 h/MIC90 were calculated.RESULTS: Gemifloxacin had lower sensitivity to common pathogenic bacteria in urinary tract. Urinary peak concentration (Cmax) of gemifloxacin was(144±124) μg/mL and the area under urine concentration-time curve (AUC24 h) was(1368±671) μg·mL-1·h after orally administered gemifloxacin mesylate tablets (320 mg) to healthy subjects. Cmax/MIC90 of gemifloxacin in urine against Escherichia coli, Pseudomonas aeruginosa and Enterococcus faecalis was 2.9-5.8 and AUC24 h/MIC90 was more than 30, whereas AUC24 h/MIC90 of gemifloxacin against Klebsiella pneumoniae and Enrerococcus feces was 19.25.CONCLUSION: Gemifloxacin could effectively remove Escherichia coli, Pseudomonas aeruginosa and Enterococcus faecalis infected in urinary tract, and avoid resistance. Gemifloxacin could inhibit growth of Klebsiella pneumoniae and Enterococcus feces.
