摘要
目的建立乳酸左氧氟沙星氯化钠注射液杂质谱,并对已知杂质进行毒性预测。方法参照《中华人民共和国药典》(2015年版)左氧氟沙星有关物质的检查方法对乳酸左氧氟沙星氯化钠注射液杂质谱进行研究,结合处方与工艺分析杂质来源及归属,研究处方中含金属络合剂对本品杂质的影响程度;同时采用ADME/T性质预测软件对已知的相关杂质进行毒理性质参数预测。结果乳酸左氧氟沙星氯化钠注射液杂质谱中主要有8个杂质,4个降解杂质为杂质B、E、F、G和4个未知工艺杂质,制剂中检出杂质主要来源于原料,E为原料生产控制的关键杂质,G为制剂质量控制的关键光降解杂质,各杂质均存在不同程度的毒性。结论乳酸左氧氟沙星杂质谱的建立可为乳酸左氧氟沙星氯化钠注射液的一致性评价提供数据参考。
Objective To establish the impurity profile of levofloxacin lactate and sodium chloride injection,and predict the toxicity of the identified impurities.Methods The impurity profile of levofloxacin lactate and sodium chloride injection was studied according to the inspection method of levofloxacin related substances in ChP 2015 edition.Together with the prescription and process,the source and attribution of impurity were analyzed and the influence of metal complexing agent in the prescription on the impurities of the product was studied.At the same time,ADME/T property prediction software was used to predict the toxicological properties of the known impurities.Results Eight main impurities were found in levofloxacin lactate and sodium chloride injection,four degradation impurities B,E,F,G and four unknown process impurities,the impurities in preparations mainly come from raw materials,and key impurity E was key factor in raw materials producing control,impurities G,the light degradation impurity,was the key factor for quality control.All impurities were toxic with different levels.Conclusion The establishment of impurity profile of levofloxacin lactate can provide a data reference for consistency evaluation of levofloxacin lactate and sodium chloride injection.
