摘要
目的:了解人血浆中奥美拉唑浓度。方法:使用内标法,对10名健康志愿者的奥美拉唑血药浓度进行HPLC法检测。结果:分析结果显示,HPLC法的方法回收率为98.32%-104.96%,线性范围10~2000μg/L;10名志愿者的tmax=(2.09±0.75)h,t1/2=(1.02±0.58)h,ρmax=(774.56±340.46)μg/L,MRT0→1=(3.02±0.83)h,AUC0→12=(1751.42±1230.68)μg·h/L,AUC0→∞=(1784.50±1298.44)μg·h/L。结论:HPLC法测定奥美拉唑浓度,其灵敏度高,专属性强,准确,简便。
Objective: To understand the human plasma concentration of omeprazole. Methods: Using the internal standard method, 10 healthy volunteers on plasma concentrations of omeprazole HPLC assay. Results: The analysis showed, HPLC method recovery was 98.32%-104.96%, linear range of 10-2 000 μg/L; 10 volunteers the tmax=(2.09 ± 0.75) h, t1/2=(1.02±0.58) h, ρmax=(774.56±340.46) μg/L, MRT0→1=(3.02±0.83) h, AUC0→12=(1 751.42±1 230.68) μg·h/L, AUC0→∞=(1 784.50±1 298.44) μg·h/L. Conclusion: HPLC determination of omeprazole concentrations, that is sensitivity, specific, accurate and simple.
