OTTAWA - Health Canada is advising Canadians that Pro Doc Limitée is voluntarily recalling two lots of irbesartan tablets because of a nitrosamine impurity, N-nitrosodiethylamine (NDEA). The lots were distributed in Quebec only.
NDEA is classified as a probable human carcinogen, which means that long-term exposure could increase the potential risk of cancer. Pro Doc Limitée is conducting the recall after testing identified levels of NDEA above what is considered reasonably safe if the drug were taken over a lifetime.
Irbesartan is an angiotensin receptor blocker (ARB) drug, also known as a sartan. Sartans are a class of drugs used to treat patients with high blood pressure to help prevent heart attacks and stroke. They are also used in patients who have had heart failure or a recent heart attack.
There have been multiple recalls of products containing other sartans in Canada and internationally since July 2018 because of nitrosamine impurities (see links below for more information). Health Canada continues to work with companies and international regulatory partners, including the U.S. Food and Drug Administration and the European Medicines Agency, to assess the issue of nitrosamine impurities in certain sartan drugs, its root causes and mitigation measures.
The irbesartan active pharmaceutical ingredient (API) in the recalled lots is manufactured by Teva API India Ltd. An API is the active ingredient in a drug that produces an effect on the body. APIs are used in the manufacturing of finished dosage form drugs (such as pills, capsules or tablets).
As with previous recalls involving nitrosamine impurities, Health Canada is advising that there is no immediate risk to patients taking these medications, since the potential risk of cancer is with long-term exposure to the impurities that exceed safe levels. Patients should not stop taking their medication unless advised to do so by their health care provider.
There are alternative products currently available on the Canadian market. Health Canada continues to monitor the supply situation. Health Canada encourages Canadians to visit drugshortagescanada.ca for information on drug shortages and discontinuances. Patients with questions or concerns about any drug they are taking, including on what to do if that drug is not readily available, should speak to their healthcare professional.
The following Pro Doc Limitée irbesartan products are being recalled because of an NDEA impurity. Health Canada maintains a complete list of sartan drugs that have been recalled because of nitrosamine impurities on its website.
