摘 要 目的:评价兰索拉唑片(受试制剂)与兰索拉唑胶囊(参比制剂)的人体生物等效性。方法:血浆样品采用液-液萃取处理,
HPLC法测定。18名健康受试者随机分组、自身交叉口服单剂量受试制剂和参比制剂进行生物等效性评价。结果:受试制剂的AUC0 t ,
AUC0∞,Cmax,tmax,t1/2分别为4.70±0.57 mg·h·L-1,5.10±0.58 mg·h·L-1,1.33±0.10 mg·L-1,2.5±0.1 h,2.2±0.4 h。参比制剂的
AUC0t,AUC0∞,Cmax,Tmax,t1/2分别为4.62±0.59 mg·h·L-1,4.98±0.63 mg·h·L-1,1.32±0.08 mg·L-1,2.5±0.1 h,2.0±0.2 h,受
试制剂相对参比制剂的人体相对生物利用度F1 为(102.2±10.1)% ,F2为(103.1±9.2)%。受试制剂相对参比制剂的主要药动学参数经
交叉试验方差分析示无统计学差异(P均>0.05),两制剂的AUC0t,AUC0∞,Cmax,经双单侧t检验示90%置信区间均位于有效置信区间
80%~125%范围内。结论:受试制剂和参比制剂具有生物等效性。

ABSTRACT Objective:To study the bioequivalence between lansoprazole tablets and capsules。Method:Plasma samples were extracted by liquid liquid extraction,and HPLC was used to assay the lansoprazole concentration in plasma。Eighteen healthy human volunteers were divided randomly into 2 groups,and a crossover,single oral dose of lansoprazole at the dose of 30 mg of tested tablets and reference capsules were delivered,respectively。Result:AUC0t,AUC0∞,Cmax,tmax,t1/2of test tablets and reference capsules were (4.70±0.57)mg·h·L-1,(5.10±0.58)mg·h·L-1,(1.33±0.10)mg·L-1,(2.5±0.1)h,(2.2±0.4)h,and (4.62±0.59)mg·h·L-1,(4.98±0.63)mg·h·L-1,(1.32±0.08)mg·L-1,(2.5±0.1)h,(2.0±0.2)h,respectively。The bioavailability F1 and F2 of test tablets vs reference capsules were(102.2±10.1)% and (103.1±9.2)% (n=18)。Main pharmacokinetic parameters between test tablets and reference capsules showed no statistical diference based on analysis of variance(P>0.05)。Conclusion:The test tablets and reference capsules are bioequivalent。
