Daiichi Sankyo receives Japanese approval for methylene blue injection 50 mg

Daiichi Sankyo Company,  a global pharmaceutical company,  has received approval in Japan for the manufacture and marketing of the methemoglobinemia treatment, methylene blue injection 50 mg (methylthioninium chloride hydrate) for toxic methemoglobinemia.

Toxic methemoglobinemia is a toxic disorder in which the methemoglobin concentration in the blood is elevated due to various substances found in drugs, pesticides, etc., causing symptoms such as cyanosis, headache, dizziness, shortness of breath, and loss of consciousness.

Methylene blue is one of the agents publicly offered for development by the Review Committee on Unapproved Drugs and Indications with High Medical Needs), set up by the Ministry of Health, Labour and Welfare (MHLW). Daiichi Sankyo acquired sole development and marketing rights for Japan from Provepharm SAS before developing Methylene Blue. In March 2014, Daiichi Sankyo filed an NDA for the manufacture and marketing in Japan for the indication. Daiichi Sankyo received a grant from Pharmaceutical Development Support Center for the development.

In order to collect data on both the safety and efficacy of Methylene Blue, Daiichi Sankyo will conduct a drug use-results survey covering all patients treated with the product during a certain period following its launch.
