How Failure Mode and Effects Analysis can structure nitrosamine formation-risk assessment without replacing scientific judgment.
FMEA can organize the multiple factors that contribute to nitrosamine formation and help teams document where prevention and verification efforts should be concentrated.
Failure modes
Potential nitrosamine-forming scenarios can be mapped across raw materials, synthesis, degradation, excipients, processing and storage.
Severity and occurrence
The method can separate the seriousness of a potential nitrosamine issue from the likelihood that the formation scenario occurs.
Prioritization
Risk ranking can help identify where confirmatory testing or mitigation should be focused.
Caution with scoring
Numerical scores are decision-support tools and should not be presented as universal regulatory cutoffs.
Frequently asked questions
Does FMEA prove that a nitrosamine is present?
No.
Can FMEA support testing prioritization?
Yes.
Are RPN cutoffs universal?
No.
Should chemical mechanism still be reviewed?
Yes; FMEA organizes the assessment but does not replace chemistry and toxicology.
