目的:探讨注射用头孢硫脒质量差异的来源及其与临床不良反应(adverse reaction,ADR)发生的关联性.方法:基于国家评价性抽验和不良反应数据,利用多变量数据分析方法(单因素方差分析、多重比较、相关性分析、线性拟合等),从常规质控项目(质量属性)和晶型(工艺属性)2个角度探讨该药物粉针产品间质量差异及其对临床安全性的影响.结果:注射用头孢硫脒所有质控项目中,仅杂质B和ADR严重报告数呈显著相关,且其差异主要来源于原料贮存和运输或制剂无菌分装过程.晶型与杂质B间拟合相关性最高(相关系数r=0.72),且高ADR严重报告数制剂企业的药物晶型(晶型A和晶型B的混晶状态)区别于较低报告数企业的晶型(较单一晶型C),推测杂质B和晶型控制是有效降低ADR发生的关键因素.结论:可尝试通过优化结晶工艺来获取单一优势晶型C提高头孢硫脒稳定性,以降低药物在贮存或分装阶段的质量(尤其是杂质B)变化,以期达到降低注射用头孢硫脒临床ADR的发生率.
