[USA Today] A recall of common blood pressure medication losartan has been expanded for a fifth time after manufacturer Torrent Pharmaceuticals found a possibly carcinogenic impurity in more batches of the drug, federal health officials said.
Three additional lots of losartan potassium tablets and two additional lots of losartan potassium/hydrochlorothiazide tablets were under recall, the U.S. Food and Drug Administration said Thursday.
The lots contained levels of N-Nitroso-N-methyl-4-aminobutyric acid (NMBA) above the acceptable daily intake levels determined by the FDA. NMBA is a "potential human carcinogen," the FDA says.
The recall comes amid a larger string of recalls of blood pressure medications valsartan, losartan and irbesartan that contain trace levels of carcinogens NMBA, N-Nitrosodimethylamine (NDMA) and N-Nitrosodiethylamine (NDEA), the FDA says. |
