GSK Recalls Popular Heartburn Drug Zantac Globally After Cancer Scare

GlaxoSmithKline (GSK.L) on Tuesday said it is recalling the popular heartburn medicine Zantac in all markets as a “precaution”, days after the U.S. Food and Drug Administration found “unacceptable” levels of probable cancer-causing impurity in the drug.

Zantac, also sold generically as ranitidine, is the latest drug in which cancer-causing impurities have been found. Regulators have been recalling some blood pressure and heart failure medicines since last year.

Britain’s medicines watchdog said GlaxoSmithKline (GSK) was recalling four prescription-only Zantac medicines: a syrup, an injection and tablets of 150 and 300 milligram (mg) dosages. (bit.ly/2IATooO)

Over-the-counter 75 mg dosage Zantac products are produced by a different company and are not affected by the recall, it added.

“GSK informed the MHRA of our decision to suspend the release, distribution and supply of all dose forms of Zantac products,” a company spokesman confirmed to Reuters.

“GSK is continuing with investigations into the potential source of the NDMA,” he said, adding that the investigations include continued engagement with its suppliers and with external laboratories to conduct tests on finished product batches of Zantac.

The Medicines and Healthcare products Regulatory Agency (MHRA) said healthcare professionals were told on Monday to “stop supplying the products immediately, quarantine all remaining stock and return it to their supplier”.

“We are advising that patients should not to stop taking their medication, and do not need to see their doctor until their next routine appointment but should seek their doctor’s advice if they have any concerns,” the MHRA said. – Reuters
