摘 要:目的:研究阿莫西林颗粒剂在健康志愿者体内的生物利用度及生物等效性。方法:20例健康志愿者随机交叉口服两种阿莫西林颗粒剂各500 mg,以对氨基苯甲酸为内标,采用HPLC-UV法测定血中药物浓度。结果:健康志愿者口服两种阿莫西林颗粒剂500 mg后,cmax分别为(13.51±3.71)μg.mL-1和(13.69±3.46)μg.mL-1;tmax分别为(1.0±0.3)h和(1.0±0.2)h;AUC0-8h分别为(29.65±5.53)μg.h.L-1和(30.87±5.80)μg.h.L-1;t1/2分别为(1.17±0.18)h和(1.30±0.32)h。各参数经统计学配对t检验,均无显著性差异(P>0.05)。结论:两种阿莫西林颗粒剂在健康志愿者体内的药动学参数相似,具有生物等效性。Objective:To study the bioavailability and bioequivolence of amoxicillin granule in healthy male volunteers. Methods: Twenty healthy volunteers were administered with amoxicillin granule 500 mg in a random crossover study. Plasma concentration was detected by reverse-phase HPLC and the internal standard was para-amino benzoic acid. Results: The statistic data of the main pharmacokinetic parameters were as follows : tmax were ( 1.0 ± 0. 3 ) h and ( 1.0 ±0. 21 ) h, Cmax were ( 13.51 ± 3.71)μg·h·L^-1 and (13.69 ±3.46) μg·h·L^-1 ; t1/2 were (1.17 ±0. 18)h and (1.30 ±0. 32)h, AUC0-8h were (29. 65 ±5. 53)μg·h·L^-1 and (30. 87 ±5. 80)μg·h·L^-1, respectively. Conclusion: There are no significant difference of the pharmacokinetic parameters between the two amoxicillin granules.
