目的:建立测定人血浆中齐拉西酮浓度的方法.方法:采用反相高相液相色谱法,色谱柱为美国Diamonsil C18,流动相为乙腈:甲醇:缓冲液(三乙胺5mL加入水1 000mL中,冰醋酸调节pH值至3.2)=28:12:60,流速为1.3 mL·min-1,检测波长为254nm,进样量为20μL.结果:齐拉西酮血药浓度在0.022～2.816 μg·mL-1范围内线性关系良好(r=0.999 2,n=8),定量下限为0.022μg·mL-1.结论:本方法快速、简便、准确、灵敏度高、重现性好,可以用于齐拉西酮临床研究和血药浓度监测.%OBJECTIVE: To establish the method for the determination of ziprasidone in human plasma ? METHODS: RP-HPLC method was adopted. The determination was performed on Diamonsil? C18(250 mm×4.6 mm, 5μm) with mobile phase consisted of acetonitrile: methanol: buffer (triethylamine 5 mL added into water 1 000 mL, pH value adjusted to 3.2 using glacial acetic acid)(28:12:60) at the flow rate of 1.3 mL-min-1.The detection wavelength was set at 254 nm and injection volume was 20 μL. RESULTS: The linear range of ziprasidone were 0.022~2.816 μg·mL-1(r=0.999 2,n=8). The lowest limit of quantisation was 0.022 μg·mL-1. CONCLUSIONS:It appears to be a rapid,convenient, accurate, sensitive and reproducible method for clinical research and plasma concentration monitoring of ziprasidone.
