Enhancing nitrosamines analysis: a focus on NDSRIs

Exploring the complexities of nitrosamines to enhance understanding and overall management, with a focus on nitrosamine drug substance-related impurities (NDSRIs).

About this on-demand webinar

For a long time in many different sectors nitrosamines have been, are and will continue to be a concern for human safety – and an essential impurity to be kept under control through risk assessment and management.

Over the last 15 years Mérieux NutriSciences have been working on nitrosamines in different sectors, such as cosmetics, packaging, tobacco and food.1 In 2019 the first nitrosamines alerts and related pharmaceutical products recalls led the US Food and Drug Administration (FDA), European Medicines Agency (EMA) and other Competent Authorities to request that the pharma industries evaluate the risk of the presence of nitrosamine impurities in human medicinal products in a broader and more extensive way.2

Following the risk evaluation phase, we are now in the confirmatory test phase, in which it is important to have specific, selective and very sensitive analytical methods to adequately respond to the needs of the market and its regulations.3

This on-demand webinar provides an overview, at different levels, of the complex and articulated topic of nitrosamines. To enhance understanding and overall management, at the safety level our speakers combine the analytical and scientific aspects with the regulatory and assessment details. They particularly focus on emerging nitrosamines for the pharma industry: nitrosamine drug substance-related impurities (NDSRIs). Some case studies conclude at an analytical level.
