FDA provides update on its ongoing investigation into valsartan products; and reports on the finding of an additional impurity identified in one firm’s already recalled products

The U.S. Food and Drug Administration is updating the public on the agency’s ongoing investigation surrounding the recent voluntary recall of several drug products containing the active pharmaceutical ingredient (API) valsartan, used to treat high blood pressure and heart failure. The FDA’s latest testing of products shows an additional unexpected impurity in three lots of Torrent Pharmaceuticals’ recalled valsartan drug products. This second impurity, N-Nitrosodiethylamine (NDEA) is a known animal and suspected human carcinogen. These Torrent products were included in the company’s recall on August 23, 2018.
