The recall of Valsartan has proved a critical need of a rational risk assessment strategy for potential nitrosamines in pharmaceutical products.
At the #VLGenotoxic 2023 event, along with focussing on the N-nitrosamines, we will explore the most important aspects around the detecting and reporting of genotoxic impurities, current investigations and regulatory, toxicological, analytical, pharmaceutical relevant prospects related to GTIs, as well as recent advances and further development and future considerations towards the different types of impurities present in drugs.
Join the keynote presentations and case studies, participate in the interactive panel discussions and Q&As, visit exhibitions, and extend partnership opportunities while learning about the advanced strategies and perspectives in the landscape of impurities and E&L at the 7th Impurities: Genotoxic, Nitrosamine & Beyond conference on March 15-16, 2023.Read more
