The Shanghai Municipal Drug and Food Administration has revoked the Drug Production License of Shanghai Hualian Pharmaceutical Factory, which allegedly sickened over a hundred leukemia patients who took doses of the company's Methotrexate and Cytarabine medicines.

In addition, SMDFA has confiscated all of the factory's illegal income from the sales of these medicines. And the police have detained the managers who were found hiding information when the government was investigating their products. A special work team has been set up to handle compensation for the victims.

Under the guidance of and with the participation of a joint investigation team set up between the Ministry of Health and State Drug and Food Administration, concerned departments in Shanghai identified the cause of the accident: Hualian's staff mixed Vincristine Sulfate into Methotrexate for injection and Cytarabine for injection, and this caused damage to the drugs and made them unqualified and unusable.
