摘  要:目的:研究中国健康志愿者单次和多次口服巴洛沙星片的药动学。方法:12名健康志愿者,男女各半,单次给药试验口服(100 mg、200 mg、400 mg)3个剂量,多次给药试验口服剂量为每次200 mg,每日1次,连续5 d。采用高效液相色谱-紫外检测法测定巴洛沙星血药浓度,用DAS 2.0软件计算药动学参数。结果:主要药动学参数如下,单剂量(100 mg)c_(max)(1.42±s 0.25)mg·L^(-1),t_(max)(0.8±0.4)h,t_(1/2)(7.4±2.7)h,AUC_(0~∞)(9.8±1.7)mg·h·L^(-1);单剂量(200 mg)c_(max)(2.9±0.6)mg·L^(-1),t_(max)(0.9±0.4)h,t_(1/2)(7.2±1.1)h,AUC_(0~∞)(21±3)mg·h·L^(-1);单剂量(400 mg)c_(max)(5.6±1.4)mg·L^(-1),t_(max)(1.2±0.4)h,t_(1/2)(8.4±2.2)h,AUC_(0~∞)(44±12)mg·h·L^(-1)。多剂量c_(max)(2.9±0.8)mg·L^(-1),t_(max)(0.83±0.19)h,t_(1/2)(8.2±2.0)h,AUC_(0~∞)(21±5)mg·h·L^(-1),FI(93.7±1.4)%。结论:巴洛沙星在人体内符合二室模型,一级动力学过程。AIM: To study the pharmacokinetics of balofloxacin tablets after single or multiple doses orally taken in Chinese healthy volunteers. METHODS: Twelve Chinese healthy volunteers (6 males, 6 females) were given single splitting of oral doses of 100 mg, 200 mg, 400 mg and multiple oral doses (200 mg daily for 5 days) of balofloxacin tablets. The concentrations of balofloxacin in plasma were measured by HPLC-UV and the pharmacokinetic parameters were calculated by DAS 2.0 software. RESULTS: The main pharmacokinetic parameters of balofloxaein tablet as splitting single orally taken doses for 100 mg, 200 mg and 400 mg were Cmax (1.42 ± S 0.25), (2.9 ± 0.6) and (5.6 ± 1.4) v (0.8 ± 0.4), (0.9 ± 0.4) and (1.2 ± 0.4) h; t1/2 (7.4 ± 2.7), (7.2 ± 1.1) and (8.4 ± 2.2) h; AUC0-∞ (9.8 ± 1.7), (21 ± 3) and (44 ± 12) mg·h·L^-1, respectively. Those for multiple orally taken dose were Cmax (2.9 ± 0.8) mg·L^-1,tmax(0.83 ± 0.19) h, t1/2 (8.2 ± 2.0) h, AUC0-∞ (21 ± 5) mg·h·L^-1 and FI (93.7 ± 1.4) %. CONCLUSION: The plasma concententration-time data of balofloxacin in human being coincide with a two compartment model and a first order kinetic processes in disposition in Chinese volunteers.
