Since the initial Valsartan contamination incident in 2018, the issue of N-Nitrosamines has continued to present major challenges for the pharmaceutical industry.  This webinar will seek to chart the evolution of the issue, from the initial concerns relating to formation of Nitrosamines during the synthesis of the drug substance, to the wider challenges of the risk of formation of Nitrosamine Drug Substance related impurities (NDSRIs). It will discuss the evolution of the regulatory framework and associated risk assessment tools and how knowledge has shaped this. it will look to highlight the remaining challenges, including in particular the analytical challenges of this ultra trace analysis paradigm we are in.
