We have already written at length about the nationwide litigation alleging contamination of Valsartan, Losartan, and Irbesartan, with carcinogenic substances. Basically, the claims are that generic versions of those drugs were being made overseas using poor manufacturing processes that caused the drugs to be tainted with impurities.
That contamination included the probable human carcinogen N-nitrosodimethylamine (NDMA), prompting mass recalls by the Federal Drug Administration (FDA). Those pending lawsuits point out that NDMA is the substance actually used in research facilities to induce cancer in lab rats. Accordingly, individual claims in those cases allege serious injuries such as liver damage and various cancers (including liver, kidney, colorectal, and gastric cancers).
