Quinapril recall:

Lupin Pharmaceuticals Inc, Solco, and Pfizer recalled several batches of Quinapril and Accupril in 2022 due to the presence of a nitrosamine impurity called N-Nitroso-Quinapril.
Nitrosamines are fairly common carcinogens found in water and foods, including cured and grilled meats, dairy products and vegetables. Everyone is exposed to some level of nitrosamines, but being exposed to them above acceptable levels over long periods of time may increase the risk of cancer. As of January 2023, Quinapril has been discontinued by all manufacturers.

Is Quinapril the same as Lisinopril?

Quinapril and Lisinopril belong to the same class of medications called angiotensin converting enzyme (ACE) inhibitors. As such, they are both prescribed as antihypertensive
drugs to treat high blood pressure. Studies have shown that lisinopril is better than quinapril in reducing blood pressure after 4 and 8 weeks of active treatment.
