NMBA is a "potential human carcinogen," the 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.Hundreds of lots of the medication have been recalled since last July.The drugs, angiotensin II receptor blockers (ARBs), work by widening or relaxing blood vessels, thus lowering blood pressure.
