Indian firm pulls heart drug from US amid cancer risk probes
India's Hetero Drugs is recalling some batches of its blood pressure and heart medicine valsartan in the US amid a wider probe into cancer risks associated with the drug. Hetero was found to be using a similar manufacturing process to China's Zhejiang Huahai Pharmaceutical for the drug. Valsartan made by Zhejiang had been found to contain a probable human carcinogen.
