摘    要:目的:建立阿莫西林血浓度的HPLC测定法,并用于人体生物等效性研究。方法:采用随机双交叉实验设计,20名健康受试者分别口服阿莫西林受试制剂和参比制剂500mg,HPLC法测定血浆中的阿莫西林浓度。结果:受试制剂和参比制卉4的AUC0-8。分别为(29.80±4.26)mg·h·L^-1、(31.05±4.12)mg·h·L^-1;AUC0-∞分别为(30.66±4.57)mg·h·L^-1、(31.86±4.15)mg·h·L^-1;Cmax分别为(10.99±1.55)mg·L^-1、(10.95±1.64)mg·L^-1;tmax分别为(1.33±0.38)h、(1.31±0.39)h;t1/2分别为(1.52±0.35)h、(1.48±0.41)h。受试制剂的相对生物利用度为(96.2±9.1)%。两制剂的AUC0-∞、Cmax、tmax、t1/2差异无统计学意义(P〉0.05)。结论:两制剂具有生物等效性。

Abstract:Objective: To establish a method to study the relative bioavailability of amoxicillin suspension in chinese healthy volunteers. Method: Twenty male healthy volunteers were received 500 mg amoxicillin praeparatums orally in a random crossover design. Drug concentrations in plasma were determined by HPLC. Result: The main pharmacokinetic parameters of tested suspension and reference granule were as follows: AUC0-8: (29.80 ±4. 26) mg·h·L^-1 vs (31. 05 ±4. 12) mg·h·L^-1 ,AUC0-∞ : (30. 66 ±4. 57) mg·h·L^-1 vs (31.86 ±4. 15) mg·h·L^-1,Cmax: (10.99 ±1.55) mg.L^-1 vs (10.95 ±1.64) mg.L^-1,tmax:(1.33±0.38) hvs (1.31±0. 39) h,t1/2 ( 1.52 ± 0. 35 ) h vs ( 1.48 ± 0.41 ) h. respectively. The relative bioavailability of the tested tablet was ( 96. 2 ± 9. 1 ) %. Conclusion: The results demonstrated that the tested tablet and reference tablet are hioequivalent.
Keywords:Amoxieillin  Bioequivalence  HPLC
