The European Medicines Agency said Monday that European authorities are stepping up supervision of the Zhejiang Huahai Pharmaceutical Industry (600521.SS). A possible carcinogen was discovered in the company's Valsartan, an antihypertensive drug.
The European Medical Authority said Monday that European authorities will now monitor the production of other active substances produced by Huahai Pharmaceutical Industry more closely.
European authorities said late last month that they found Huahai Pharmaceuticals did not comply with good production practices and that the company was no longer authorized to produce valsartan at its offshore pharmaceutical plant in China.
In July, Huahai pharmaceutical recalled valsartan in the United States. It was found that one of the impurities in the drug might cause cancer.
Regulators in Europe and North America last month found a second toxin in Valsartan that could cause cancer in humans.
