The presence of N-nitrosodimethylamine in several high blood pressure and heart disease medications manufactured in China has spurred their recall across Europe, officials said July 5.

The presence of N-nitrosodimethylamine in several high blood pressure and heart disease medications manufactured in China has spurred their recall across Europe, officials said July 5. The European Medicines Agency said the recall followed identification of the impurity in the active substance valsartan manufactured by Zhejiang Huahai Pharmaceuticals. Britain's Medicines and Healthcare Products Regulatory Agency said the appearance of N-nitrosodimethylamine, which may cause cancer, came after a change in the process for making valsartan at one plant. European officials said they are working to assess the extent of the matter.
