Background: Early antidepressant Active Pharmaceutical Ingredients (API) like Imipramine hydrochloride and Clomipramine hydrochloride have not been assessed for Genotoxic Impurities (GTI) as per ICHM7. Objective: The main aim of the study was to develop a new simple and sensitive method for the determination of genotoxic impurities in Imipramine hydrochloride and Clomipramine hydrochloride active pharmaceuticals ingrediens. Methods: A simple, selective, and sensitive gas chromatography (GC) liquid injector method was developed for the quantitative determination of N, N-Dimethyl amino propyl chloride (DAPC) in API s. This method provided an excellent sensitivity and a typical target analyte level of 4.0 ppm. The DPAC content in the sample was analyzed on ZB-624, 30m x 0.53mm x 3.0μm column interfaced with a flame ionization detector (FID). The developed method was validated as per ICH guidelines. Results: The validated method showed good linearity over the concentration range of LOQ to 120% (1.18ppm to 4.8ppm) with a correlation coefficient of 0.9986. Limit of detection (LOD) and limit of quantitation (LOQ) were found to be 0.36 ppm and 1.18 ppm, respectively. This method showed high sample recovery (>90.0%). Conclusion: The developed method was a simple and sensitive gas chromatography liquid injector method. This method was validated as per ICH guidelines and could be very useful for the determination of a potential genotoxic impurity (DAPC) in imipramine hydrochloride and clomipramine hydrochloride active drug substance quality checking and ensuring safety of the patients.

GC-FID 定量分析盐酸丙咪嗪和盐酸氯米帕明中的基因毒性杂质 N, N-二甲基氨基丙基氯

背景:早期抗抑郁药物活性药物成分 (API),如盐酸丙咪嗪和盐酸氯米帕明,尚未根据 ICHM7 评估基因毒性杂质 (GTI)。目的:本研究的主要目的是建立一种简便、灵敏的新方法,用于测定盐酸丙咪嗪和盐酸氯米帕明活性药物成分中的遗传毒性杂质。方法:开发了一种简单、选择性和灵敏的气相色谱 (GC) 液体注射器方法,用于定量测定 API 中的 N, N-二甲基氨基丙基氯 (DAPC)。该方法提供了出色的灵敏度和 4.0 ppm 的典型目标分析物水平。样品中的 DPAC 含量在 ZB-624,30m x 0.53mm x 3.0μm 色谱柱上与火焰离子化检测器 (FID) 接口进行分析。根据 ICH 指南对开发的方法进行了验证。结果:经验证的方法在 LOQ 至 120%(1.18ppm 至 4.8ppm)的浓度范围内显示出良好的线性,相关系数为 0.9986。发现检测限 (LOD) 和定量限 (LOQ) 分别为 0.36 ppm 和 1.18 ppm。该方法显示出高样品回收率 (>90.0%)。结论:该方法是一种简单、灵敏的气相色谱液体注射法。该方法根据 ICH 指导原则进行了验证,对于盐酸丙咪嗪和盐酸氯米帕明活性原料药质量检查和确保患者安全的潜在遗传毒性杂质 (DAPC) 的测定非常有用。经过验证的方法在 LOQ 至 120%(1.18ppm 至 4.8ppm)的浓度范围内显示出良好的线性,相关系数为 0.9986。发现检测限 (LOD) 和定量限 (LOQ) 分别为 0.36 ppm 和 1.18 ppm。该方法显示出高样品回收率 (>90.0%)。结论:该方法是一种简单、灵敏的气相色谱液体注射法。该方法根据 ICH 指导原则进行了验证,对于盐酸丙咪嗪和盐酸氯米帕明活性原料药质量检查和确保患者安全的潜在遗传毒性杂质 (DAPC) 的测定非常有用。经过验证的方法在 LOQ 至 120%(1.18ppm 至 4.8ppm)的浓度范围内显示出良好的线性,相关系数为 0.9986。发现检测限 (LOD) 和定量限 (LOQ) 分别为 0.36 ppm 和 1.18 ppm。该方法显示出高样品回收率 (>90.0%)。结论:该方法是一种简单、灵敏的气相色谱液体注射法。该方法根据 ICH 指导原则进行了验证,对于盐酸丙咪嗪和盐酸氯米帕明活性原料药质量检查和确保患者安全的潜在遗传毒性杂质 (DAPC) 的测定非常有用。发现检测限 (LOD) 和定量限 (LOQ) 分别为 0.36 ppm 和 1.18 ppm。该方法显示出高样品回收率 (>90.0%)。结论:该方法是一种简单、灵敏的气相色谱液体注射法。该方法根据 ICH 指导原则进行了验证,对于盐酸丙咪嗪和盐酸氯米帕明活性原料药质量检查和确保患者安全的潜在遗传毒性杂质 (DAPC) 的测定非常有用。发现检测限 (LOD) 和定量限 (LOQ) 分别为 0.36 ppm 和 1.18 ppm。该方法显示出高样品回收率 (>90.0%)。结论:该方法是一种简单、灵敏的气相色谱液体注射法。该方法根据 ICH 指导原则进行了验证,对于盐酸丙咪嗪和盐酸氯米帕明活性原料药质量检查和确保患者安全的潜在遗传毒性杂质 (DAPC) 的测定非常有用。
