摘 要:目的:研究静脉滴注盐酸卡屈沙星葡萄糖注射液在健康人体内的药动学。方法:20名健康成年志愿者随机分成两组,每组10人,男女各半,分别静滴盐酸卡屈沙星葡萄糖注射液0.3和0.4 g后,采用HPLC法测定血药浓度,使用DAS软件求出药动学参数。结果:两组的最大血药浓度(Cmax)分别为(5.2±0.6)和(7.3±1.7)μg.mL-1;消除半衰期(t1/2z)分别为(6.4±1.4)和(6.3±1.4)h;表观分布容积(Vz)分别为(90.9±22.7)和(83.4±21.3)L;清除率(CL)分别为(9.8±1.6)和(9.3±1.7)L.h-1;药时曲线下面积(AUC0~24)分别为(30.5±5.2)和(42.2±8.2)μg.h.mL-1。结论:t1/2z,Vz和CL经统计学检验,两组间无显著性差异,Cmax和AUC0~24与给药剂量呈正比。Objective: To investigate the pharmacokinetics of caderofloxacin hydrochloride after intravenous infusion in glucose injections in Chinese healthy volunteers. Methods: Totally 20 healthy volunteers were divided into two groups, 10 volunteers (5 men and 5 women) per group. Volunteers in each group were intravenously infused with 0.3 g or 0.4 g caderofloxacin hydrochloride in glucose injection, respectively. The plasma concentrations were determined by HPLC method. The pharmacokinetic parameters were calculated by DAS software. Results: The main pharmacokinetic parameters were as following : Cmax of two groups, (5.2± 0.6) and (7.3 ±1.7)μg·h·mL^-1; t1/2z, (6.4±1.4) and (6.3±1.4) h; Vz, (90.9±22.7) and (83.4±21.3) L; CL, (9.8±1.6) and (9.3 ±1.7) L·h^-1; AUC0-24, (30.5 ±5.2) and (42.2±8.2) ~g'h'mL-l, respectively. Conclusion: There are no remarkable differences in pharmacokinetic parameters ( Vz, CL, t1/2z) between two groups. There is a positive correlation between the dose and AUC0-24 or Cmax.
