摘要
目的:研究阿立哌唑片在中国健康志愿者体内的药动学。方法:单剂量试验组:10名健康志愿者(男女各半),分3阶段先后单剂量口服阿立哌唑10,20,40mg。多剂量试验组:12名健康志愿者(男女各半),连续口服阿立哌唑20mg(qd,连续14d)。血药浓度采用HPLC法测定,以计算其主要药动学参数并进行统计学分析。结果:单剂量口服阿立哌唑10,20,40mg后,主要药动学参数分别如下:AUC0。为(16431.8±2350.5)、(40184.0±5256.7)和(71629.1±8616.5)μg·h·L^-1;tmax为(4.4±1.3)、(4.2±0.8)和(4.3±0.9)h;Cmax为(187.2±20.9)、(410.1±58.3)和(700.8±143.6)μg·L^-1;t1/2β为(83.22±9.43)、(75.11±10.06)和(84.17±22.43)h。方差分析结果显示各剂量的主要药动学参数AUC0-1,tmax,Cmax,和t1/2β均没有性别间差异。多利量口服阿立哌唑片20mg达到稳态后的主要药动学参数如下:AUCss^τ为(11961.1±2675.7)μg·L^-1;fmax^ss为(4.4±1.2)h;Cmax^ss为(634.2±137.1)μg·L^-1;Cmin^ss为(361.3±95.7)μg·L^-1;Cav为(498.4±111.5)μg·L^-1;DF为(55.6±7.5)%,t1/2β为(66.42±12.65)h。经方差分析,除tmax^ss外,多剂量主要药物动力学参数性别间无显著性差异。结论:健康志愿者单剂量和多剂量口服阿立哌唑片后体内药物浓度呈二室模型变化规律;在10-40mg剂量范围内,血药峰浓度及血药浓度-时间曲线下面积与剂量之间呈线性关系,其主要药动学参数无性别差异。
OBJECTIVE To research the pharmacokinetics of aripiprazole in healthy volunteers after administration with single or multiple dose of aripiprazoLe, and compare its gender difference. METHODS In single dose study, 6 male and 6 female volunteers received a single dose of 10,20,40 mg aripiprazole tablets, respectively in 3 stages. In multiple dose study, other 6 male and 6 female volunteers administered aripiprazole tablets(20 mg, qd, for 14 days). Aripiprazole concentration in plasma was determined by HPLC. Main pharmacokinetic parameters were calculated and compared by statistic analysis. RESULTS The pharmacokinetic parameters obtained from the single-dose study of 10,20,40 mg were, respectively, as follows: AUG0-t (16431.8±2350.5),(40184.0±5256.7)and(71629.1±8616.5)μg·h·L^-1;tmx(4.4±1.3),(4.2±0.8)and(4.3±0.9)h; Cmax ( 187. 2 ± 20. 9), (410. 1 ± 58. 3) and (700. 8 ±143. 6) μg·L^-1 ; t1/2,β (83.22 ± 9. 43), (75. 11 ± 10. 06) and (84. 17 ± 22. 43) h. The steady-state pharrnacokinetic parameters were as follows: AUCss^t (11961.1 ± 2675.7)μg·h·L^-1 ;tmax^ss为(4. 4 ± 1.2)h; Cmax^ss(634.2± 137. 1)μg·L^-1;Cmin^ss(361.3±95.7)μg·L^-1;Cav(498.4±111. 5)μg·L^-1;DF(55.6±7.5) %;t1/2β(66.42± 12.65) h. Statistical analysis indicated that there was no gender difference in pharmacokinetic parameters, except of tmax^ss in multiple dose study. CONCLUSION The concentration-time curves of aripiprazole are fitted to a two-compartment model. In the dose range of 10-40 mg, Cmax and AUC0-t: follow the rule of dose-dependant manner. There was no gender difference in the main pharmacokinetic parameters.
