For the last few years, our very own Dr. Aloka Srinivasan has been participating in several conferences and workshops related to controlling nitrosamine impurities in pharmaceuticals and successfully working with 505(b)(2) NDAs.
In 2021 and 2022, Dr. Srinivasan participated in a meeting of trade associations and the U.S. FDA to discuss the hardships experienced by innovators, generic drug manufacturers, and over-the-counter drug manufacturers in detection, control, and risk mitigation related to nitrosamine impurities and the use of molecular weight corrections in justifying acceptable intakes of nitrosamine impurities.
Dr. Srinivasan is also a member of the 505(b)(2) Platform and participated in several workshops related to challenges experienced by the industry in developing products that may fit the 505(b)(2) pathway. Interested in having Dr. Srinivasan speak or provide her expertise at a relevant meeting, event, or conference?
