What are nitrosamines? ​

Long-term ingestion of Nnitroso-quinapril may be associated with an increased cancer risk in humans.

Nitrosamines are present in water and foods such as cured and grilled meats, dairy products and vegetables. Although everyone is exposed to some level of nitrosamines, the FDA set an internationally recognized acceptable daily intake limit for the impurity. The FDA recommends that drugs containing levels above the acceptable daily intake limit be recalled as appropriate.​

A person taking a drug that contains nitrosamines at or below the acceptable daily limit every day for 70 years is not expected to have an increased cancer risk, according to the FDA.
