摘要
目的建立莫达非尼血药浓度的高效液相色谱(HPLC)测定法,进行单、多剂量在人体的药动学研究。方法采用HPLC-UV法测定健康受试者口服莫达非尼片(单剂量含莫达非尼100,200,400 mg和多剂量)后血浆中莫达非尼浓度。结果单剂量口服莫达非尼(100,200和400 mg)后,估算的莫达非尼的药动学参数:t_(1/2β)分别为(15.7±s 1.0),(16.4±1.2),(15.6±1.3)h;CL分别为(2.2±0.3),(2.02±0.28),(2.2±0.4)L·h^(-1);t_(max)分别为(1.5±0.3),(1.7±0.3),(1.58±0.29)h;c_(max)分别为(3.0±0.5),(5.5±0.9),(11.4±1.5)mg·L^(-1);V_d分别为(56±20),(61±20),(57±11)L;AUC_(0~60)分别为(42.0±2.9),(74±6),(144±15)mg·h·L^(-1);AUC_(0~∞)分别为(50.4±2.4),(83±5),(154±15)mg·h·L^(-1);MRT_(0~60),兮别为(16.8±0.9),(17.4±1.0),(15.7±1.5)h。多剂量口服莫达非尼(100 mg,bid×7 d)血药浓度达稳态后估算的莫达非尼的药动学参数c_(max)^(ss)为(4.9±0.7)mg·L^(-1),t_(max)为(1.6±0.5)h,c_(min)^(ss)为(2.01±0.24)mg·L^(-1),c_(ax)为(3.2±0.4)mg·L^(-1),波动系数DF为(0.92±0.17),AUC_(0~12)^(ss)为(38±5)mg·h·L^(-1)。结论本方法准确、灵敏、可靠,莫达非尼在大部分人体内的过程符合二室开放模型,其主要药动学参数与国外文献报道数据一致,可为临床给药方案提供参考。
AIM To establish a HPLC-UV method for studying the pharmacokinetics of modafinil tablet with single and multo-dose in healthy volunteers. METHODS Healthy volunteers received tested tablets individually of a single oral dose containing modafinil 100, 200, 400 mg and multidose. Drug concentrations in plasma were determined by HPLC-UV. RESULTS The main pharmacokinetic parameters of single oral doses (100, 200, 400 mg) were as follow: t±β (15.7 ± s 1.0), (16.4 ± 1.2), (15.6 ± 1.3) h; CL (2.2 ± 0.3), (2.02 ± 0.28), (2.2 ± 0.4) L.h^-1; tmax (1.5 ± 0.3), (1.7 ± 0.3), (1.58 ± 0.29) h; cmax (3.0 ± 0.5), (5.5 ± 0.9), (11.4± 1.5) mg·L^-1; Va (56±20), (61±20), (57±11) L; AUC0-60 (42.0±2.9), (74±6), (144± 15) mg·h·L^-1; AUC0-60(50.4 ± 2.4), (83 ± 5), (154 ± 15) mg·h-L^-1; MRT0-60 (16.8 ± 0.9), (17.4 ± 1.0), ( 15.7 ± 1.5) h. The main pharmacokinetic parameters of multidose ( 100 mg, bid × 7 d) under stable concentratione were as follow: c^ss max (4.9 ± 0.7) mg·L^-l, tmax (1.6 ± 0. 5) h, c^ss max (2.01 ± 0.24) mg·L^-l, c^ss max (3.2 ± 0.4) mg·L^-l, DF (0.92 ± 0.17), AUC^ss 0-12 (38 ± 5) mg·h·L^-l. CONCLUSION The method is accurate, sensitive and reliable, coincided with a two-compartment open pharmacokinetic model for modafinil plasma concentration-time data analysis. The main pharmacokinetic parameters of the domestic modafinil tablet were similar to those reported abroad, providing information for clinical application.
