Torrent Pharmaceuticals announced that it has expanded its voluntary recall of blood pressure medications after testing revealed trace amounts of a known probable human carcinogen.
The company added five lots of the generic drug losartan (three lots of losartan potassium tablets and two lots of losartan potassium/hydrochlorothiazide tablets) to an April recall of more than 100 lots of the same medications. The lots similarly were found to contain N-methylnitrosobutyric acid (NMBA) above the acceptable daily intake levels released by the U.S. Food and Drug Administration (FDA).
Patients currently taking the medication should continue doing so “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,” the company said in a statement posted on the FDA website.
The FDA began testing all heart drugs called angiotensin II receptor blockers for impurities after July 2018, when traces of the carcinogen N-nitrosodimethylamine (NDMA) were found in blood pressure medications from different companies that contained valsartan from a Chinese supplier.
