The Food and Drug Administration (FDA, Agency, or we) is announcing the establishment of a docket to solicit public comments on the identification, assessment, and control of N-nitrosamine (nitrosamine) drug substance-related impurities (NDSRIs) that may be considered by the Agency in its regulation of these types of impurities in drug products. This notice identifies scientific and regulatory considerations regarding the identification, assessment, and control of NDSRIs, including areas that may benefit from collaborative efforts, and requests comments on these topics. This notice is not intended to communicate FDA's regulatory expectations on these issues but is instead intended to seek input from the public to inform scientific and/or regulatory approaches as appropriate.
The agency’s own summary, as published.
