摘要: 目的:建立人血浆中盐酸洛美利嗪浓度HPLC-MS 测定方法。方法:LC-ESI-MS 选择性离子监测方法测定人血浆中盐酸洛美利嗪浓度。色谱柱为Lichrospher C18柱, 流动相为0.01 mol/L 醋酸铵缓冲液(乙酸调pH 3.5):甲醇= 22:78, 流速为1.0 mL/min 。结果:盐酸洛美利嗪在0.10 ~10.02 ng/mL 范围内线性关系良好(r =0.9993), 最低检测浓度为0.10 ng/mL 。高、中、低三种浓度的批内和批间变异均小于8.59 %;绝对回收率在85.58 % ~ 92.03 %;相对回收率在100.2 % ~105.9 %。20 名男性健康志愿者单剂量随机交叉口服盐酸洛美利嗪胶囊(10 mg) 和参比制剂盐酸洛美利嗪片(10 mg), 经HPLC-MS 法测定盐酸洛美利嗪的血药浓度, 受试制剂的相对生物利用度为103.4 %±15.6 %。结论:本法具有快速、简便、灵敏、准确等特点, 适合人血浆中盐酸洛美利嗪浓度测定。

Abstract: AIM: To develop a HPLC-MS method for determining the concentration of lomerizine hydrochloride in human plasma.METHODS: Lomerizine was determined by LC-ESI-MS selection ion measurement.Separation was performed on a Lichrospher C18 with a mobile phase of 0.01mol/L ammonium acetate (pH 3.5):methanol (22:78).RESULTS: Calibration curves were linear in the concentration range of 0.10-10.02 ng/mL (r =0.9993).The quantitative detection limit in plasma was 0.10 ng/mL.RSD of intra-batch and inter-batch assays were all less than 8.59 %.The relative recovery ranged from 100.2 %to 105.9 %and the absolute recovery ranged from 85.58 % to 92.03 %.A single oral dose 10 mg lomerizine hydrochloride capsule or tablet was given to 20 healthy volunteers according to an open randomized crossover study.The concentration of lomerizine hydrochloride in plasma was determined by HPLC-MS method, and the relative bioavailability of AUC0 ~ 24 was 103.4 % ±15.6 %.CONCLUSION: This method is rapid, simple, sensitive and accurate for the determination of lomerizine hydrochloride in human plasma.
