Navigating Nitrosamines – Back to Basics
Nitrosamines have been the compounds of interest for the pharmaceutical industry in recent years due to the mutagenic nature of these impurities. This all started with one nitrosamine impurity N-Nitroso dimethylamine (NDMA) and eventually the list expanded to many nitrosamines in various drug substances and drug products.
More recently nitroso-drug substance-related impurities (NDSRI) became the major concern for the industry. As per regulations, any possibility for the formation of Nitroso impurity in the synthetic route or the manufacturing process of the drug substance must be evaluated, and steps must be taken to identify, quantify and minimize/eliminate such impurities. So, the presence of robust methods for the detection and quantitation of such impurities is the need of analytical laboratories. By attending this session, you will understand that the discussion will focus on helping companies getting started in their journey with nitrosamines. It will cover the steps companies need to take to ensure they have a sufficient nitrosamines risk assessment.
