摘要: 目的 建立一种简便的HPLC 方法测定人体盐酸氟桂利嗪血药浓度,并评价两种盐酸氟桂利嗪制剂的生物等效性。方法 以地西泮为内标,血样经正己烷提取后,采用Diamonsil C18 柱,以0.06 mol·L-1醋酸钠(pH =3.76)-乙腈(45∶55)为流动相,流速为1.0 ml·min-1,波长254 nm。利用3p97 程序处理所得数据,求出各种参数,评价生物等效性。结果 本方法最低检测限为2.5μg·L-1,盐酸氟桂利嗪在2.5 ~ 160.0μg·L-1范围内线性关系良好(r =0.9989)。两制剂间AUC 、Cmax、Tmax、t 1/2β经统计学检验无显著性差异(P>0.05)。供试制剂的相对生物利用度为(98.41±11.23)%(n =20)。结论 本HPLC方法简便可行;两种制剂生物等效。

Abstract: AIM: To establish a simple HPLC method for determining flunarizine hydrochloride in humanPlasma and to study bioequivalence between twoPreparations.METHODS: The drug and internal standard(diazepam)were extracted from thePlasma with n-hexane.The HPLC method wasPerformed with a diamonsil C18 column,and the mobilePhase was 0.06 mol·L-1sodium acetate(pH =3.76)-acetonitrile(45∶55).The flow rate was 1.0 ml·min-1and the wavelength was 254 nm.The data obtained were fitted with 3p97Program on computer to evaluate the bioequivalence.RESULTS: The calibration curve waslinear in the range of 2.5 -160μg·L-1(r =0.9989).The minimum detection concentration was 2.5μg·L-1.The values of AUC,Cmax,Tmax,and t1/2βof twoPreparations had no significant difference(P>0.05).The relative bioavailability was(98.41±11.23)%(n =20).CONCLUSION: This HPLC method is simple,and twoPreparations of flunarizine hydrochloride are bioequivalent.
