Zantac: CVS latest to suspend heartburn drug over cancer fears – BBC News
On 13 September, both the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) published their decisions to review the presence of N-nitrosodimethylamine (NDMA) in medicines containing the drug ranitidine.
NDMA is classified as a probable human carcinogen (a substance that could cause cancer) on the basis of animal studies.
NDMA is found in water and foods, including meats, dairy products, and vegetables, but is not expected to cause harm when ingested in very low levels, EMA says.
Ranitidine products are used to reduce the production of stomach acid in patients with conditions such as heartburn and stomach ulcers.
They are available over-the-counter and on prescription.
