摘    要:目的评价2种恩替卡韦制剂在健康人体的生物等效性。方法采用随机、双周期、自身交叉的试验设计。24例健康男性志愿者单次口服试验制剂(恩替卡韦分散片)或参比制剂(恩替卡韦片)1 mg,血浆样品采用HPLC-MS/MS法测定,计算两者的主要药物动力学参数,进行生物等效性评价。结果恩替卡韦血药浓度在0.0520 mg·L-1与峰面积线性关系良好(r2=0.999 8),最低定量浓度为0.05μg·m L-1,批内及批间精密度RSD<15%;服用试验制剂或参比制剂后血浆中恩替卡韦的Cmax分别为(10.51±3.11)和(10.25±2.98)μg·L-1;tmax分别为(0.63±0.21)和(0.62±0.40)h;t1/2分别为(62.35±30.26)和(60.48±26.54)h;AUC020 mg·L-1与峰面积线性关系良好(r2=0.999 8),最低定量浓度为0.05μg·m L-1,批内及批间精密度RSD<15%;服用试验制剂或参比制剂后血浆中恩替卡韦的Cmax分别为(10.51±3.11)和(10.25±2.98)μg·L-1;tmax分别为(0.63±0.21)和(0.62±0.40)h;t1/2分别为(62.35±30.26)和(60.48±26.54)h;AUC0分别为(35.22±9.50)和(34.61±7.90)μg·h·L-1;AUC0∞分别为(35.22±9.50)和(34.61±7.90)μg·h·L-1;AUC0tn分别(28.91±6.63)和(28.58±5.73)μg·h·L-1;试验制剂的相对生物利用度F0tn分别(28.91±6.63)和(28.58±5.73)μg·h·L-1;试验制剂的相对生物利用度F0tn、F0tn、F0分别为(101.25±12.02)%和(102.99±20.40)%。结论试验制剂和参比制剂具有生物等效性。

Abstract:Objective To evaluate the bioequivalence of entecavir hydrochloride dispersible tablets in healthy volunteers. Methods A single oral dose of entecavir hydrochloride test and reference preparations was given to 24 healthy volunteers, in a two-way cross-over test. The concentration of entecavir was determined by HPLC-MS/MS. The pharmacokinetic parameters and bioequivalence of the 2 preparations were analyzed. Results The linear range of entecavir hydrochloride in the plasma was from 0.05 to 20 μg·mL^-1(r2= 0.999 8) and the limit of detection was 0.05 μg·L^-1; the intra-day and inter-day precision was less than 15%. The main pharmacokinetic parameters of the 2 preparations were as follows: Cmax(10.51±3.11) and(10.25±2.98) μg·L^-1; tmax(0.63±0.21) and(0.62±0.40) h; t1/2(62.35±30.26) and(60.48±26.54) h; AUC0 -∞(35.22±9.50) and(34.61±7.90) μg·h·L^-1; AUC0 - tn(28.91±6.63) and(28.58±5.73) μg·h·L^-1; F0 - tn and F0 -∞ of test preparation were(101.25±12.02)% and(102.99±20.40)%. Conclusion The test preparation is bioequivalent to the reference preparation.
