A billion-dollar pharmaceutical company has extended its national recall of a drug used to treat high blood pressure and congestive heart failure for the fourth time since December after a small amount of a possible cancerous agent was detected, federal officials said on Thursday.
India-based Torrent Pharmaceuticals has expanded its recall in the United States to include thousands upon thousands of other Losartan Potassium and Losartan Potassium / Hydrochlorothiazide tablets due to the detection of an "unexpected impurity": N-methylnitrosobutyric acid (NMBA) in an active ingredient.
NMBA, a potential cancer-causing impurity, was found at levels above the FDA's acceptable daily intake recommendations, Torrent said. No adverse health effects were reported related to the recall, the company said.
Consumers who take the affected medication should talk to their doctors about withdrawal before they stop taking the medication, or if they have experienced any adverse effects that may be related to the medication.
Losartan is used to treat high blood pressure, heart and left ventricular diseases and nephropathy in patients with type 2 diabetes, among others. Losartan potassium and hydrochlorothiazide tablets are also used to treat high blood pressure and heart problems, but are not used to treat nephropathy.
Other manufacturers have withdrawn losartan in recent months, but some have involved potential contaminants. Be sure to contact your doctor or pharmacist if you have any questions about losartan in general.
