摘要
目的建立高效液相色谱一质谱联用(HPLC-MS/MS)法测定人血浆富马酸卢帕他定浓度。方法以氯雷他定为内标,待测血浆样品经氢氧化钠碱化,加醋酸乙酯-二氟甲烷(4:1)萃取后,用液-质联用方法进行检测。结果血浆富马酸卢帕他定的浓度线性范围为0.05—13.00μg·L^-1,最低定量浓度为0.05μg·L^-1;提取回收率为65.06%-73.25%。结论该法分离效果良好,灵敏度高,回收率高,可用于人体血药浓度测定及药动学研究。
Objective An HPLC-MS/MS method was established for the determination of rupatadine fumarate in plasma. Methods The drug and internal standard (loratadine)in plasma were alkalified with sodium hydroxide, extracted with acetic ether-dichloromethane (4 : 1 ) and detected by HPLC-MS/MS. Results A good linearity of rupatadine fumarate in plasma was obtained from 0.05 to 13 μg · L^-1 , the minimum level of which was 0.05 μg · L^-1 and the recovery rate was from 65.06% to 73.25%. Conclusion The method is sensitive, accurate and reliable, and could be used for determing drug concentration and pharmacokinetic of rupatadine fumarate.
