Valsartan was previously recalled in 22 other countries, according to CNN. The current recall is centered around valsartan manufactured in Linhai, China, FDA officials said.
Authorities believe the impurities were caused by a change in the way the drug was manufactured. Officials said in an update last week that the FDA is working with drug manufacturers “to ensure future valsartan active pharmaceutical ingredients are not at risk of NDMA formation.”
Authorities continue to investigate.
