摘要: 目的:建立人血清美他多辛浓度的HPLC 测定法, 进行美他多辛健康志愿者药代动力学研究。方法:志愿者含药血清经去蛋白处理后, 以甲醇-5 mmol·L-1乙酸铵(14:86) 为流动相, 采用Diamonsil C18 柱(250 mm ×4.6 mm, 5 μm) 分离, 流速1.0 ml·min-1, 检测波长286 nm。结果:本法线性范围0.2 ~ 12 μg·ml-1, 最低定量限0.2 μg·ml-1。血清中美他多辛绝对回收率73.31 %~ 82.00 %, 方法回收率91.08 %~ 95.69 %, 日内RSD ≤6.3 %, 日间RSD≤4.3 %。结论:本法简单、快速、灵敏、重现性好, 是一种有效的检测人血清美他多辛浓度的方法,适用于人体美他多辛药代动力学研究。

Abstract: AIM: To establish an HPLC method for determination of metadoxine in human serum and to study the pharmacokinetics of metadoxine in healthy Chinese volunteers.METHODS: The volunteer serum samples were deproteinized and separated on a Diamonsil C18 column (250 mm ×4.6 mm, 5 μm), eluted with the mobile phase of methanol-5 mmol·L -1 ammonium acetate (14:86, v/v) at a flow rate of 1.0 ml·min -1 and detected at 286 nm.RESULTS: The linear range of the calibration curve for metadoxine was 0.2 ~ 12 μg·ml -1, and the low limit of quantitation (LLOQ) was 0.2 μg·ml -1.The absolute and relative recoveries were 73.31 %~ 82.00 % and 91.08 %~ 95.69 % respectively.Within-day RSD and between-day RSD were less than 6.3 % and 4.3 %.CONCLUSION: The assay method is simple, sensitive, accurate, and reproducible and was successfully applied for the pharmacokinetic study of metadoxine in healthy volunteers.
