Drugmaker Pfizer issued a voluntarily recall of three prescription blood pressure medications — one name brand and two generics — due to the presence of elevated levels of a potentially cancer-causing impurity.
The impurity, N-nitroso-quinapril, was found in six lots of Accuretic, one lot of the generic form of quinapril and hydrochlorothiazide, and four lots of quinapril HCl/hydrochlorothiazide tablets.

The recalled tablets were packaged in 90-count bottles and distributed to wholesalers and distributors across the U.S. and Puerto Rico from November 2019 to March 2022. Some expiration dates extend into 2024. Pfizer distributed Accuretic, the name-brand medication, and Greenstone, a subsidiary of Pfizer, distributed the generic tablets.
To date, Pfizer is not aware of any adverse reactions to the recalled drugs.
Last year, two blood pressure medications sold by Lupin Pharmaceuticals were recalled due to a similar cancer-causing impurity.

What are nitrosamines?
Long-term ingestion of N-nitroso-quinapril, a type of nitrosamine, may be associated with a potential increased cancer risk in humans. However, there is no immediate risk to patients taking the recalled medications, according to Pfizer.
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. For drugs that contain levels above the acceptable daily intake limit, the FDA recommends they be recalled by the manufacturer 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.
