摘    要:目的:研究朝鲜族和汉族健康受试者口服单剂量氯沙坦钾片的药代动力学.方法:健康受试者20名(朝鲜族10名,汉族10名,男女各半),口服单剂量氯沙坦钾片剂50mg;用HPLC-荧光法测定氯沙坦及其代谢物E-3174血药浓度,采用DAS软件和SPSS软件进行数据处理和统计学分析.结果:单剂量口服50 mg氯沙坦钾片后,朝鲜族受试者的氯沙坦和E-3174的主要药动学参数如下:Cmax分别为(524±349),(493±188)ng·mL-1;tmax分别为(0.9±0.4),(2.4±0.8)h;t1/2(1.5±0.4),(3.1±0.7)h;AUC0-24分别为(682±319),(2563±752) ng·h·mL-1;AUC0-∞分别为(752±331),(2608±766)ng·h·mL-1.汉族受试者的氯沙坦和E-3174的主要药动学参数如下:Gmax分别为(351±168),(242±60)ng·mL-1;tmax分别为(1.4±1.1),(3.6±1.7)h;t1/2分别为(0.8±0.4),(4.7±1.1)h;AUC0-24分别为(498±172),(1853±194) ng·h·mL-1;AUC0-∞分别为( 523±184),(1960±182) ng-h·mL-1.结论:氯沙坦钾片在朝鲜族和汉族健康受试者体内药动学参数差异存在统计学意义,在不同性别间药动学参数差异无统计学意义,个体间药动学参数存在较大差异,临床治疗中应实行个体化给药方案.

Abstract:Objective: To study the pharmacokinetics of losartan potassium tablet after a single oral dose in Korean and Han healthy volunteers. Methods: Twenty volunteers including ten Korean volunteers and ten Han volunteers were involved in the study. Each subject received a single dose of 50 mg losartan potassium tablet. The concentration of losartan and its metabolite E-3174 in plasma was determined by HPLC-fluorescence (FLU) method, the pharmacokinetic parameters were calculated by DAS software and compared by SPSS software. Results: The main pharmacokinetic parameters of Korean (losartan and E-3174) were as follows: Cmax (524 ± 349), (493 ±188) ng.mL^-1, tmax (0.9 ± 0.4), (2.4 ± 0.8) h; tl/2 (1.5 ± 0.4), (3.1 ± 0.7) h; AUC0a4(682 ± 319), (2563 ± 752) ng. h. mL^-1; AUC0-∞(752 ± 331), (2608 ± 766) ng. h. mL^-1. The main pharmacokinetic parameters of Han (losartan and E-3174) were as follows: Cm~x(351 ± 168), (242 ± 60) ng.mL^-1; tin,x(1.4 ±1.1), (3.6 ± 1.7) h; tv2(0.8 ±0.4), (4.7 ± 1.1) h; AUC0.24(498 ± 172), (1853 ±194) ng.h.mL^-1; AUC0-∞(523 ± 184), (1960 ± 182) ng.h.mL^-1. Conclusion: There was significant difference of the main pharmacokinetic parameters between Korean and Han population. There was no significant difference of the main pharmacokinetic parameters between the males and females. The individualizing dosage regimens of losartan should be applied in the clinical treatment.
