The alarm over the valsartan drug was first raised in July, prompting a global recall of affected pills. The EMA initially said the problem likely dated back to changes in manufacturing processes at Zhejiang Huahai Pharmaceutical in 2012.
But N-nitrosodimethylamine, a probable human carcinogen, was also found in batches of valsartan made by Zhejiang Tianyu, although at much lower levels than in the case of Zhejiang Huahai, the EMA said in a statement.
