目的:建立盐酸氨溴索口服液中抑菌剂及矫味剂含量测定方法并考察全国范围内该品种抑菌剂和矫味剂添加情况.方法:采用资生堂MGII C18(250 mm×4.6 mm,5μm)色谱柱,以0.02 mol·L-1乙酸铵溶液(用冰醋酸调节pH至4.5)-甲醇为流动相,梯度洗脱,流速1.0 mL·min-1,柱温为30℃,DAD检测器,检测波长为254 nm和230 nm.结果:盐酸氨溴索与4种抑菌剂、3种矫味剂色谱峰均能良好分离,并质量浓度分别在0.005~0.15 mg· mL-1范围内,苯甲酸钠(r=1.000)、羟苯甲酯(r=0.9990)、羟苯乙酯(r=0.9999)、羟苯丙酯(r=1.000)、AK糖(r=0.9998)、糖精钠(r=1.000)、阿司帕坦(r=1.000),线性关系良好(n=6).防腐剂苯甲酸钠、羟苯甲酯、羟苯乙酯、羟苯丙酯及矫味剂AK糖、糖精钠、阿司帕坦的定量下限分别为4.23、0.10、0.20、0.21、2.0、4.3、20.1 ng;平均回收率(n=9)分别为101.2%、102.3%、101.0%、101.2%、100.8%、100.2%和100.7%.对全国范围内22个生产企业的样品进行测定,个别企业抑菌剂的种类和量与生产处方不一致.结论:所建立方法准确性,专属性良好,可用于盐酸氨溴索口服液中抑菌剂及矫味剂的测定.

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
