摘要: 目的: 研究兰索拉唑肠溶片与肠溶胶囊在健 康人体的生物等效性。 方法: 20 名健康志愿者采用 双周期交叉试验, 单剂量空腹口服兰索拉唑肠溶片 和肠溶胶囊各 30 mg, HPLC 法测定其血清中兰索拉 唑浓度, 血药浓度-时间数据经DAS 2.0 统计软件处 理, 计算主要药代动力学参数, 并进行两种制剂的生 物等效性评价。结果: 兰索拉唑肠溶片与肠溶胶囊 的主要药代动力学参数:t1/2 为1.808±1.031和1.341 ±0.498 h 、Cmax 为 0.764 ±0.385 和 0.902 ±0.369 μg·ml-1 、Tmax 为 3.639 ±0.744 和 2.500 ±1.000 h、 AUC 0-10h 为3.024 ±1.941和3.098 ±1.742 μg·h·ml-1。 兰索拉唑肠溶片的相对生物利用度为 109.57%± 59.48%。结论: 两种制剂具有生物等效性。

Abstract: AIM: To investigate the bioequivalence of lansoprazole enterosoluble tablets and capsules in Chi-nese healthy volunteers.METHODS: Twenty volunteers were randomly divided into two groups (test and refer-ence), with double cross over design.The concentration of lansoprazole in serum was determined by HPLC and pharmacokinetic parameters were calculatedwith DAS 2.0 practical pharmacokinetics program.RESULTS: The pharmacokinetic parameters of lansoprazole enterosoluble tablets and capsules were as follows:t1/2 were 1.808 ± 1.031 and 1.341 ±0.498 h, Cmax were 0.764 ±0.385 and 0.902 ±0.369 μg·ml-1, Tmax were 3.639 ±0.744 and 2.500±1.000 h, AUC 0-10h were 3.024±1.941 and 3.098±1.742 μg·h·ml-1。 The relative bioavalibility of lansoprazole enterosoluble tablets was 109.57% ± 59.48%. CONCLUSION: The statistical analysis showed that the test and reference preparation were bio-equivalent.
