Methylene blue

Methylene blue (also known as methylthioninium chloride) is a compound consisting of dark green crystals or crystalline powder, having a bronze-like luster. Solutions in water or alcohol have a deep blue color. Methylene blue is commonly used dye that also exhibits antioxidant, antimalarial, antidepressant and cardioprotective properties. The intravenous (IV) form of methylene blue is approved by the United States (US) Food and Drug Administration (FDA) for the treatment of pediatric patients and adult patients with acquired methemoglobinemia. Historically, it had been widely used in Africa to treat malaria, but it disappeared when chloroquine and other drugs entered the market. Its use as a urinary tract antiseptic has also been investigated. Methylene blue is also an investigational drug that has been shown in early clinical trials to be an inhibitor of tau protein aggregation and, therefore, the drug is of potential interest for the treatment of patients with Alzheimer's disease. Finally, methylene blue has been investigated for the treatment of ifosfamide-induced encephalopathy.

Affygility Solutions has an occupational exposure limit (OEL) and control band assignment for this active pharmaceutical ingredient (API). This monograph also contains the acceptable daily exposure (ADE) value.
