Valisure’s early investigations into medication quality revealed N,N-Dimethylformamide (DMF), a probable human carcinogen, in specific batches of valsartan, a widely used blood pressure medication. DMF had recently been reclassified as a Group 2A carcinogen by the World Health Organization (WHO) and the International Agency for Research on Cancer (IARC), signaling heightened global concern around its presence in the drug supply.

This discovery marked Valisure’s first Citizen Petition to the FDA, spotlighting serious flaws in the pharmaceutical manufacturing process and raising new questions about the adequacy of existing quality control systems for imported drug ingredients.

Valisure’s testing methodology and findings catalyzed widespread industry discussion and were prominently covered by major media outlets.
