Pfizer Inc. has said that it will be recalling some lots of a high blood pressure drug and two authorized generic versions due to the presence of elevated levels of a potential cancer-causing impurity, nitrosamine.
The pharmaceutical giant will be pulling six lots of Accuretic tablets, one lot of quinapril and hydrochlorothiazide, and four lots of quinapril HCI/hydrochlorothiazide tablets due to the presence of nitrosamine.
Pfizer said that it has not received any adverse events related to this recall.
The company noted that everyone is exposed to nitrosamines, but exposure above acceptable levels over prolonged periods of time can increase the risk of cancer. Nitrosamines are common in water and foods; including grilled meats, dairy products and vegetables.
Earlier this month, Pfizer Canada recalled Accuretic due to the presence of the same impurity. However, Pfizer claims there is no immediate risk to those taking the drug.
Patients that are currently taking any of the recalled products should consult with their doctor about alternative treatment options.
