Objective: To establish a stable and reliable gas chromatography-tandem mass spectrometry method for the determination of N-nitrosodimethylamine (NDMA) in metformin hydrochloride sustained-release tablets, and to optimize extraction conditions by investigating the effects of isopropyl alcohol and thioglycerin on the stability of the tested solution.
Methods: Separation was achieved on AB-InoWax capillary column (30 m×0.25 mm×0.25 μm) with polyethylene glycol as the stationary phase. Electron ion(EI) source and multiple reaction monitoring (MRM) mode were used. Quantitative determination was performed by both external standard and internal standard.
Results: The addition of thioglycerin could significantly improve the stability of the test solution. NDMA showed good linearity within the concentration range of 0.25-50 ng·mL-1(r>0.999). The detection limit of the method was 0.1 ng·g-1 and the quantification limit of the method was 0.2 ng·g-1. The average recoveries (n=9) were 97.3% and 94.9% while using external standard and internal standard, respectively. Precision, repeatability and stability were good with RSD less than 8%. Ninety batches of metformin hydrochloride sustained release tablets were tested. NDMA content in all detected samples were all less than 30% of the acceptable limit set by the National Medical Products Administration and FDA.
Conclusions: This method shows satisfactory sensibility, specificity, accuracy, stability and durability, which is suitable for quantitative analysis of NDMA in metformin hydrochloride sustained-release tablets, providing technical support for the quality and safety of related products.

目的: 建立一种稳定且可靠的气相色谱-串联质谱法测定盐酸二甲双胍缓释片中N-亚硝基二甲胺(NDMA),同时通过考察异丙醇和硫代甘油2个添加剂对供试品溶液稳定性的影响,确定了最优的提取条件。
方法: 采用聚乙二醇为固定相的AB-InoWax毛细管柱(30 m×0.25 mm×0.25 μm),利用电子轰击电离源(EI),在多反应监测(MRM)模式下检测,分别以外标法和内标法定量。
结果: 添加硫代甘油可显著改善供试品溶液稳定性,NDMA在0.25~50 ng·mL-1浓度范围内有良好的线性(r>0.999),方法检测限为0.1 ng·g-1,方法定量限为0.2 ng·g-1,分别在内标法和外标法计算下,平均加标回收率(n=9)均为97.3%和94.9%,精密度、重复性、稳定性及耐用性的RSD均小于8%。对90批次的盐酸二甲双胍缓释片进行检测,结果均小于国家药品监督管理局以及FDA规定的可接受限度的30%之内。
结论: 本文建立的方法灵敏度高,专属性强,结果准确且稳定性好,适用于盐酸二甲双胍缓释片中NDMA的定量分析,可为有关产品的质量安全提供技术支撑。
