摘要
目的:研究复方赖诺普利片在健康人体内药动学特征。方法:单剂量:空腹口服复方赖诺普利片1片(每片复方赖诺普利片含赖诺普利10mg、氢氯噻嗪12.5mg)。多剂量:多次给药连续9d,每天服药1次,每次1片。采用LC-MS法测定血浆中赖诺普利、氢氯噻嗪的浓度,计算药动学参数,以考察复方赖诺普利片多剂量口服达稳态过程和稳态药动学特征。结果:单剂量口服受试制剂:赖诺普利的tmax为(7.3±1.2)h;Cmax为(42.5±6.8)μg.L-1;t1/2为(8.6±1.8)h;MRT为(20.1±3.0);AUC0-72为(545.1±147.4)ng.h.L-1。氢氯噻嗪的tmax为(2.8±0.7)h;Cmax为(81.6±22.7)μg.L-1;t1/2为(13.7±2.0)h;MRT为(10.4±2.0);AUC0-48为(679.8±280.7)ng.h.L-1。多剂量口服受试制剂:赖诺普利的AUCss为(576.9±124.4)ng.h.L-1,Css-max为(47.7±13.2)μg.L-1,Css-min为(6.2±1.8)μg.L-1,Css-av为(24.0±5.2)μg.L-1,DF为(1.71±0.24),tmax为(7.3±1.1)h,t1/2为(13.1±2.7)h;氢氯噻嗪的AUCss为(731.4±224.9)ng.h.L-1,Css-max为(101.0±31.6)μg.L-1,Css-min为(8.4±3.8)μg.L-1,Css-av为(30.5±9.4)μg.L-1,DF为(3.1±1.2),tmax为(3.0±0.9)h,t1/2为(8.8±1.6)h。结论:复方赖诺普利片主要药动学参数单剂量和多剂量给药差异无显著性,复方赖诺普利片在人体内无蓄积。
OBJECHVE To assess the pharmacokinetic profiles of compound lisinopril and hydrochlorothiazide tablets by LC-MS. METHODS The single dose study was conducted in 12 healthy volunteers with a tablet of compound lisinoprll and hydrochlorothiazide tablets (10 rag/12. 5 mg) . The multiple dose study was performed in 12 healthy volunteers with a tablet of compound lisinopril and hydrochlorothiazide tablets for 9 days. The plasma concentrations of llsinoprll and hydrochlorothiazlde were measured by a fully validated LC-MS method. RESULTS The major pharmacokinetic parameters of the single dose study on an empty stomach were as follows: For Lisinopril tmax (7.3 ± 1.2) h; Cmax (42. 5 ± 6. 8) μg·L^-1; t(1/2 )(8. 6 ± 1.8) h; MRT (20. 1 ± 3.0) ; AUC(0-72) (545. 1 ± 147. 4) ng· h·L^- 1, respectively. As for hydrochlorothiazide, tmax (2. 8 ± 0. 7) h; Cmax (81.6 ± 22. 7)μg·L^-1; t(1/2) ( 13.7 ± 2. 0)h; MRT( 10. 4 ± 2. 0) ; AUC(0-48) (679. 8 ± 280. 7)ng·h·L^-1, respectively. Major pharmacokinetic parameters for multiple doses were as follows: for lisinopril, AUCss(576. 9 ± 124. 4) ng· h·L^-1 , Css-max (47. 7 ± 13.2)μg·L^-1 ,Css-min(6. 2 ± 1.8)μg·L^-1 ,Css-av (24.0±5.2) μg·L^-1 ,DF(1.71 ± 0. 24),tmax(7. 3 ± 1.1 ) h,t(1/2)(13.1 ±2. 7) h, respectively; for hydrochlorothiazide, AUCss (731.4± 224. 9) ng·h· L^-1 ,Css-max (101.0 ± 31.6) μg·L^-1, Css-min (8. 4 ± 3. 8)μg·L^-1 , Css-av (30.5±9.4)μg·L^-1,DF(3.1±1.2),tmax(3.0±0.9) h,t(1/2)(8.8±1. 6) h, respectively. CONCLUSION Thereis nosignlfcant difference in pharmacokinetic parameters of compound lisinopril and hydrochlorothlazlde tablets (10 mg/12. 5 mg) between single and multiple administration, no accumulation after administration.
