摘　　要：目的建立测定注射用亚锡二巯丁二钠中元素杂质的电感耦合等离子体质谱(Inductively Coupled Plasma-Mass Spectrometry,ICP-MS)方法。方法使用ICP-MS半定量测定模式对注射用亚锡二巯丁二钠中元素杂质进行筛查,结合人用药品技术要求国际协调理事会(ICH)Q3D元素杂质指导原则的要求,确定15种元素:锂(Li)、铝(Al)、钾(K)、钒(V)、铁(Fe)、钴(Co)、镍(Ni)、铜(Cu)、锌(Zn)、砷(As)、镉(Cd)、铟(In)、锑(Sb)、汞(Hg)和铅(Pb)作为定量考察和控制的元素杂质研究对象。ICP-MS采集模式选择动能歧视(Kinetic Energy Discrimination,KED)模式,分别以钪(Sc)、锗(Ge)、钇(Y)、铋(Bi)作为内标,采用重复采样3次的平均值报告结果。结果经元素筛查发现注射用亚锡二巯丁二钠中存在相对较高的Al、K、Fe、Zn、In 5种元素。不同企业产品元素杂质含量测定结果显示出一定的生产商分布特点。建立的定量方法验证显示,15种元素杂质在各自线性范围内响应与浓度相关性良好(r>0.9917);方法精密度(RSD≤3.72%)和重复性(RSD≤3.53%)满足测定要求;各元素平均回收率93.45%~105.38%(RSD≤4.28%,n=9),方法准确性良好。结论金属盐类制剂产品可能引入ICH Q3D元素杂质指导原则要求以外的元素杂质。本研究建立的ICP-MS定量方法简便、快速,可用于注射用亚锡二巯丁二钠中元素杂质的筛查、检测和风险评估。Objective To establish an inductively coupled plasma mass spectrometric(ICP-MS)method for the determination of elemental impurities in kits of dimercaptosuccinate acid and stannous chloride for injection.Methods The elements in kits of dimercaptosuccinate acid and stannous chloride for injection were screened using ICP-MS in a semi-quantitative mode.The elemental impurities were determined before being examined and controlled as required by the ICH Q3D guidelines for elemental impurities.There were 15 elements:Li,Al,K,V,Fe,Co,Ni,Cu,Zn,As,Cd,In,Sb,Hg and Pb,which were chosen as the subjects.The kinetic energy discrimination(KED)mode was selected for ICPMS while Sc,Ge,Y and Bi were used as the internal standards.The sampling was repeated three times to determine the average value.Results The contents of five elements-Al,K,Fe,Zn and In-were found to be relatively high in the kit of dimercaptosuccinate acid and stannous chloride for injection after elemental screening.The results of determination of elemental impurities of products by different enterprises revealed characteristics of distribution.Methodological validation indicated that the impurities of each element were within the linear range and correlated(r>0.9917),and that the precision(RSD≤3.72%)and reproducibility(RSD≤3.53%)of the method met the requirements,with the average recoveries of these elements ranging from 93.45%to 105.38%(RSD≤4.28%,n=9),and the accuracy was good.Conclusion Metal salts may introduce impurities of elements other than those required by ICH Q3D guidelines.The method established in this study is simple,rapid and can meet the requirements for the detection and risk evaluation of elemental impurities in the kit of dimercaptosuccinate acid and stannous chloride for injection.
