摘    要:目的:研究健康受试者单剂量与多剂量口服复方苯磺酸氨氯地平/阿托伐他汀钙片后的药动学。方法:10名受试者单剂量(10mg)与多剂量(10mg·d-1,连续7d)口服复方苯磺酸氨氯地平/阿托伐他汀钙片后,以高效液相色谱-电喷雾串联质谱(LC-MS/MS)法测定苯磺酸氨氯地平与阿托伐他汀钙血药浓度,利用DAS药动学软件计算药动学参数。结果:单剂量给药后,苯磺酸氨氯地平与阿托伐他汀钙的主要药动学参数分别为:t1/2(53.4±12.9)、(15.4±4.6)h,Cmax(6.7±1.8)、(18.5±4.4)μg·L-1,AUC0~120(298.8±97.1)、(118.3±48.9)μg·h·L-1,AUC0~∞(412.2±131.5)、(120.0±55.1)μg·h·L-1;多剂量给药后,苯磺酸氨氯地平与阿托伐他汀钙的主要药动学参数分别为:t1/2β(49.5±10.3)、(14.4±5.3)h,Cmax(8.7±2.5)、(20.3±5.8)μg·L-1,AUC0~120(451.2±127.1)、(136.3±54.9)μg·h·L-1,AUC0~∞(569.3±165.8)、(139.0±61.3)μg·h·L-1,Cav(2.7±0.6)、(8.3±1.3)μg·L-1,峰谷比(R)1.7±0.4、1.1±0.2。结论:复方苯磺酸氨氯地平/阿托伐他汀钙片中2组分在健康受试者体内的消除速度不随连续给药变化,但连续给药后苯磺酸氨氯地平在体内有轻微蓄积。

Abstract:OBJECTIVE: To study the pharrnacokinetics of compound amlodipine besylate/atorvastatin calcium tablets (CABACT) following oral administration of single dose vs. multiple doses in healthy volunteers. METHODS: 10 volunteers were administered a single dose of Compound amlodipine besylate/atorvastatin calcium tablets( 10 mg, p.o.)or multiple doses( 10 mg·d^-1, p.o.) for 7 days, respectively. Plasma concentrations of amlodipine besylate and atorvastatin calcium were determined by LC-MS/ MS and the pharmacokinetic parameters were calculated using DAS software. RESULTS: In single-dose study the pharmacokinetic parameters of amlodipine besylate vs. atorvastatin calcium were as follows: t1/2β ( 53.4±12.9 ) h vs. ( 15.4±4.6 ) h; Cmax ( 6.7± 1.8 )μg·L^-1 vs.(18.5±4.4)μg ·L^-1; AUC (298.8-L97.1)μg· h · L^-1 vs. (118.3±48.9)μg·L^-1; AUC0-∞(412.2±131.5) μg· h · L^-1 vs. (120.0±55.1)μg· h · L^-1 In multiple-dose study the pharmacokinetic parameters were as follows: t1/2(49.5±10.3)h vs. (14.4±5.3) h; Cmax(8.7±2.5)μg ·L^-1 vs, (20.3±5.8)μg ·L^-1; AUC0-∞(451.2±127.1)μg ·h·L^-1vs. (136.3±54.9)μg ·h·L^-1; AUC0-∞ (569.3±165.8) μg ·h·L^-1 vs. (139.0±61.3)μg ·h·L^-1; C,,(2.7±0.6),(8.3±1.3)μg L^-1 R(1.7±0.4) vs. (1.1±0.2). CONCLUSION: The elimination rates of amlodipine besylate and atorvastatin calcium do not change after oral administration of multiple doses of CABACT while slight accumulation of amlodipine besylate is founded.
