摘要/Abstract

摘要： 目的通过研究微量凝胶法确定其能否满足《中华人民共和国药典》（2020年版）（简称“《中国药典》”）要求,作为现有细菌内毒素检查法的补充。方法依据《中国药典》四部“9101 药品质量分析方法验证指导原则”规定,按照其项下“杂质测定”中“限度”项目具体要求,对微量凝胶法（5μL样品+50μL鲎试剂）进行专属性、检测限、耐用度3项内容进行验证,并采用凝胶法和微量凝胶法对85批样品进行品种适用性比较研究,对384批样品进行一致性比对研究。结果经方法学验证,微量凝胶法符合《中国药典》对定性方法的要求,微量凝胶法与凝胶法相比,品种适用性与一致性比对具有等效结果。结论微量凝胶法可以作为凝胶法的补充方法在我国推广。

Abstract: Objective To determine whether the microgel method can meet the requirements of Chinese Pharmacopoeia, as a supplement to the existing bacterial endotoxin test method. Methods According to the provisions of “9101 Guidelines for the validation of pharmaceutical quality analysis methods” in Part IV of the Pharmacopoeia of the People’s Republic of China(2020 edition), the microgel method (5 μL samples+50 μL limulus ambocyte lysate) was analyzed for “specificity”, “limit of detection” and “durability” in the item of “Determination of impurities”. The gel method and microgel method were used to compare 85 batches of samples for variety applicability and 384 batches of samples for consistency comparison. Results The microgel method was methodologically validated and showed that it met the requirements of the Pharmacopoeia of the People’s Republic of China for the qualitative methods, and the microgel method was equivalent to the gel method for the comparison of the applicability and consistency of the varieties. Conclusion The microgel method can be promoted as a supplementary alternative to the gel method in China.

Key words: bacterial endotoxin, limulus ambocyte lysate (LAL), microgel method, methodological validation, variety suitability, consistency comparison, complementary and alternative method
