摘  要:目的:进行受试制剂盐酸安非他酮缓释片与市售参比制剂盐酸安非他酮缓释片的人体生物等效性研究。方法:20例健康男性志愿者采用自身交叉给药方案,分别口服单次给予和连续多次(18例)给予2种盐酸安非他酮缓释制剂,采用HPLC-MS/MS法测定其血药浓度,计算药动学参数,并判定2种制剂的生物等效性。结果:口服单次给予受试制剂和参比制剂安非他酮缓释片的主要药动学参数为Cmax分别为(174.0±55.5),(175.1±56.2)μg.L-1,tmax分别为(2.0±0.5),(2.0±0.6)h,t1/2分别为(11.1±5.0),(11.8±8.2)h,AUC0-72分别为(952.9±423.4),(901.6±372.5)μg.h.L-1,AUC0-∞分别为(968.2±441.0),(918.8±375.8)μg.h.L-1;以AUC0-72计,单次口服受试制剂的相对生物利用度为(106.0±24.3)%。口服连续多次给予的主要药动学参数为Cmax分别为(149.1±45.1),(149.2±38.4)μg.L-1,tmax分别为(2.1±0.9),(1.8±0.3)h,t1/2分别为(12.7±4.6),(12.2±5.3)h,AUCSS分别为(717.9±195.7),(666.9±186.6)μg.h.L-1;以AUCSS计,多次口服试验药的相对生物利用度为(109.0±19.5)%。结论:2种制剂的盐酸安非他酮缓释片具有人体生物等效性。OBJECTIVE To study the bioequivalence of bupropion hydrochloride sustained-release tablets. METHOIYS A single dose and multiple oral doses of bupropion hydroehloride sustained-release tablets (the test and the reference) were given to 20 male healthy volunteers in randomized crossover design for the pharmacokinetic and relative bioavaiability study. Plasma concentrations of bupropion hydrochloride were determined by HPLC-MS-MS. RESULTS The main pharmacokinetic parameters for a single oral dose of test and reference preparation were calculated as the follows: Cmax (174. 0 ±55.5) and (175. 1 ± 56. 2) μg·L-1 ; tmax (2. 0 ± 0. 5) and (2. 0 ± 0. 6)h; t1/2 ( 11.1 ± 5.0) and (11.8 + 8.2)h; AUC0-72 (952. 9 ±423. 4) and (901.6 ±372. 5)μg·h·L-1 ; AUC0-∞ (968. 2 ± 441.0) and (918.8 ± 375.8) μg·h·L-1. The relative bioavailability of the test was (106. 0 ± 24. 3) %. The pharmacokinetic parameters of multiple doses study were as follows: Cmax(149. 1 ± 45.1) and (149. 2 ± 38. 4) μg-L-1 ; tamx(2. 1 ± 0. 9) and (1.8 ± 0. 3) h; t1/2 (12. 7 ± 4. 6)h and(12. 2 ± 5.3)h ; AUCss- (717. 9 ± 195. 7) and (666. 9 ± 186. 6)μg·h·L-1. The relative bioavailability of the test was (109. 0± 19. 5)%. CONCLUSION The statistical analysis shows the two preparations are bioequivalent.
