Nitrosamine impurities are classified as “cohort of concern” per ICH-M7 guidelines. There have been numerous drug recalls since 2018 including several sartan, ranitidine and metformin, varenicline-based drugs due to the presence of unacceptable levels of nitrosamines. Since then, nitrosamines and more recently, nitroso drug substance related impurity (NDSRIs) contamination in drugs is of increased concern by regulators as these poses significant risk to human health. According to the recent guidance published by both the FDA and EMA, nitrosamines and NDSRIs must be monitored at the low ng/mL using highly sensitive analytical methodologies. LC/MS/MS is inherently a selective and sensitive analytical technique that is well-suited for identification and quantification of nitrosamines at very low levels.


In this presentation, we will cover the accurate determination and quantitation of nitrosamine impurities and NDSRIs in drug substances and products using LC-MS/MS based analytical strategies that can readily be adopted.
