摘要
目的:筛选注射用氟康唑的制备工艺,建立其含量测定方法。方法:以pH值及助溶剂种类等为考察因素筛选处方;采用高效液相色谱法测定其含量。结果:溶液pH在6.5～8.5时制剂稳定性较好,且丙二醇可增加制剂澄明度;氟康唑检测浓度在40～200μg/ml范围内线性关系良好,平均回收率为100.37%,RSD=1.37%(n=3)。结论:按照筛选出的处方、工艺制备的注射用氟康唑质量稳定,含量测定方法准确、可行。
OBJECTIVE:To select a technique for preparation of fluconazole for injection and to establish a method for determination of its content.METHODS:The formula was selected on the basis of pH value and species of solution adjuvant.The content was determined by HPLC.RESULTS:The preparation was stable when pH value was between6.5～8.5,and its clarity could be increased by propylene glycol.The detectable concentration of fluconazole showed a good linear correlation in the range of40～200μg/ml.The average recovery was100.37%,RSD=1.37%(n=3).CONCLUSION:The fluconazole for injection prepared by the present technique is stable in quality and the method for content determination is accurate and practicable.
