摘要(Abstract):

目的探讨改进阿司匹林缓释片中释放度的测定方法。方法色谱柱为Agilent ZORBAX SB-C18(4.6 mm×250 mm,5μm);流动相为乙腈-四氢呋喃-冰醋酸-水(23∶5∶5∶61);流速为1.0 m L/min;检测波长为276 nm。结果改进后的阿司匹林释放片释放度测定结果与《国家药品标准》方法无显著差异。结论该方法操作比《国家药品标准》收载的方法更简单、快捷,方便。
OBJECTIVE To explore the improvement of release test for aspirin sustained-release tablets. METHODS HPLC was adopted using a column of Agilent ZORBAX SB-C18( 4. 6 mm × 250 mm,5 μm). The mobile phase was consisted of Acetonitriletetrahydrofuran- acetic acid-water( 23∶ 5∶ 5∶ 61) with the flow rate of 1. 0 m L / min. The detection wavelength was 276 nm. RESULTS The results of improved method has no significant difference to the results of National Drug Standards method. CONCLUSION The improved method is more simple,fast,and convenient.
