摘要: 目的:使用HPLC 法测定人血浆中左氧氟沙星的浓度, 并研究盐酸左氧氟沙星软胶囊、硬胶囊和片剂在健康人体内的药代动力学。方法:20 名健康男性志愿者单剂量口服200 mg 盐酸左氧氟沙星后,采集不同时间点血样测定血药浓度。结果:左氧氟沙星线性范围为0. 041 ~ 5. 180 mg/L, 日内和日间精密度(RSD) 均小于5. 0% 。盐酸左氧氟沙星软胶囊主要药动学参数:tmax: (0. 8 ±0. 3) h; Cmax: (2. 8 ± 0. 9) mg/L; AUC0-30: (14. 7 ± 1. 8) mg·L-1 ·h; AUC0-∞: (15. 4 ± 1. 9) mg·L-1·h; t1/2: (6. 9 ± 0. 4) h 。结论:盐酸左氧氟沙星软胶囊的药动学参数与硬胶囊和片剂的差异无统计学意义。

Abstract: AIM:To establish a HPLC method for the determination of levofloxacin in plasma and to investigate the pharmacokinetics of levofloxacin hydrochloride soft capsules, hard capsules and tablets in Chinese healthy volunteers.METHODS:20 male healthy subjects were received a single oral dose of 200 mg/Levofloxacin. The concentrations of levofloxacin in plasma were determined by HPLC.RESULTS: The linear range of levofloxacin was between 0. 041 mg/L and 5. 18 mg/L. The inter-day and intra-day RSD were less than 5% .The main pharmacokinetic parameters of levofloxacin soft capsule were as follows: tmax: (0. 8 ±0. 3) h, Cmax: (2. 8 ± 0. 9) mg/L, AUC0-30: (14. 7 ± 1. 8) mg·L-1 ·h, AUC0-∞: (15. 4 ±1. 9) mg·L-1·h, t1/2: (6. 9 ±0. 4) h. There were no statistically significant differences among the main pharmacokinetic parameters of levofloxacin hydrochloide soft capsule hard capsule and tablet.CONCLUSION:The main pharmacokinetic parameters of levofloxacin hydrochloride soft capsules were similar to those of hard capsule and tablet.

Key words: levofloxacin hydrochloride, soft capsule, HPLC, pharmacokinetics
