Torrent Pharmaceuticals recalls Losartan blood pressure medicine due to 'unexpected impurity'

Torrent Pharmaceuticals Limited is the latest pharmaceutical company to recall blood pressure medication.

According to a Dec. 20 company announcement posted by the Food and Drug Administration, two lots of Losartan potassium tablets are being voluntarily recalled at the consumer level. The recall is "due to the detection of trace amounts of an unexpected impurity found in an active pharmaceutical ingredient (API) manufactured by Hetero Labs Limited."

The impurity, called N-nitrosodiethylamine (NDEA) is found naturally in certain foods, air pollution, drinking water and industrial processes. It has been classified by the International Agency for Research on Cancer as a probable human carcinogen. It’s the same impurity that led Sandoz Inc. to recall losartan potassium hydrochlorothiazide.

According to the company, there have not been reports of reactions or incidents related to the impurity.

“Patients who are on Losartan should continue taking their medication, as the risk of harm to the patient’s health may be higher if the treatment is stopped immediately without any alternative treatment. Patients should contact their pharmacist or physician who can advise them about an alternative treatment prior to returning their medication,” recall said.
