摘要: 目的: 研究单次、多次口服奥美沙坦氢氯噻嗪片在中国健康受试者体内的药代动力学。 方法: 本研究为随机、开放、单次和多次口服给药的单中心试验。12位健康受试者单次和多次口服1片奥美沙坦氢氯噻嗪片(每片含奥美沙坦 20 mg,氢氯噻嗪 12.5 mg),采用HPLC-MS-MS法测定奥美沙坦和氢氯噻嗪的血浆药物浓度,利用DAS 2.0 和SPSS 13.0 计算药动学参数和进行统计学分析。 结果: 单次和多次口服给药后奥美沙坦的药动学参数如下:Cmax 分别为(489±122) μg/L 和(531±125) μg/L,AUC0→t分别为(3468±869) μg·L-1·h 和(3557±1209) μg·L-1·h,tmax分别为(2.6±0.5) h和(2.3±0.8) h,t1/2分别为(7.3±4.0) h和(8.3±3.6) h;单次和多次口服给药后氢氯噻嗪的药动学参数如下:Cmax 分别为(122±34) μg/L 和(182±39) μg/L,AUC0→t分别为(764±211) μg·L-1·h和(1079±361) μg·L-1·h,Cmax分别为(2.2±0.7) h和(1.6±0.6) h,t1/2分别为(6.8±2.3) h 和(7.1±1.6) h。 结论: 奥美沙坦氢氯噻嗪片主要药动学参数单剂量和多剂量给药差异无统计学意义,奥美沙坦和氢氯噻嗪在人体内均无明显蓄积。

Abstract: AIM: To study the pharmacokinetics of compound olmesartan medoxomil and hydrochlorothiazide tablets after multiple oral dose administration in Chinese healthy volunteers. METHODS: In a randomized, open, single-center study, 12 Chinese healthy volunteers were randomized to administer a single dose of compound olmesartan medoxomil and hydrochlorothiazide tablets (20 mg/12.5 mg) on day 1 and day 3 to day 9. The concentration in human plasma was determined by LC-MS/MS method and its pharmacokinetic parameters were calculated and analysed by DAS 2.0 and SPSS 13.0. RESULTS: The main pharmacokinetic parameters of olmesartan medoxomil after a single dose and multiple-dose were as follows: Cmax were (489±122) μg/L and (531±125) μg/L; AUC0→t were (3468±869 ) μg·L-1·h and (3557±1209) μg·L-1·h; tmax were (2.6±0.5) h and (2.3±0.8) h; t1/2 were (7.3±4.0) h and (8.3±3.6) h, respectively. The main pharmacokinetic parameters of hydrochlorothiazide after a single dose and multiple-dose were as follows: Cmax were (122±34) μg /L and (182±38) μg /L; AUC0→t were (764±211) μg·L-1·h and (1079±361 ) μg ·L-1·h; tmax were (2.2±0.7) h and (1.6±0.6) h; t1/2 were (6.8±2.3) h and (7.1±1.6) h, respectively. CONCLUSION: There is no significant difference in pharmacokinetic parameters of compound Olmesartan medoxomil and hydrochlorothiazide tablets (20 mg/12.5 mg) between single and multiple administration,no accumulation after administration.
