FDA Announces Virtual Public Workshop on Nitrosamines as Impurities in Drugs; Health Risk Assessment and Mitigation Workshop The Food and Drug Administration is announcing a virtual public workshop entitled: Nitrosamines as Impurities in Drugs; Health Risk Assessment and Mitigation Workshop. This workshop will be on March 29 and 30 and will include presentations and question and answer by expert panelists. The workshop will include presentations on nitrosamines chemistry and toxicology and, on the finding of nitrosamines as impurities in drugs. The presentations will be followed by open discussion of questions prepared by FDA and presented to expert panelists for deliberations over two days.
