摘要
通过对比几种双氯芬酸钠栓的含量测定方法,选择能准确而简便地测定该栓剂主药含量的方法。采用石油醚萃取法、直接冷冻法、对照品外标法分别得到检验结果。结果表明,直接冷冻法与对照品外标法均能有效测定双氯芬酸钠栓的含量。
Through the comparison of several determination methods for the contents of diclofenac sodium suppositories, the methods were selected to accurately determine the content of the main drug.The test results were respectively obtained by petroleum ether extraction method, the direct freezing method and reference standard external standard method. The results show that the direct freezing method and reference standard external standard method can effectively determine the content of diclofenac suppositories.
