Methylthioninium chloride, commonly called methylene blue, is a salt used as a dye and as a medication. As a medication, it is mainly used to treat methemoglobinemia. It has previously been used for treating cyanide poisoning and urinary tract infections, but this use is no longer recommended. Methylene blue is typically given by injection into a vein. Common side effects include headache, nausea, and vomiting. Methylene blue was first prepared in 1876, by Heinrich Caro. It is on the World Health Organization's List of Essential Medicines.

Roles Classification
Chemical Role(s): antioxidant
A substance that opposes oxidation or inhibits reactions brought about by dioxygen or peroxides.
Biological Role(s): EC 1.4.3.4 (monoamine oxidase) inhibitor
An EC 1.4.3.* (oxidoreductase acting on donor CH-NH2 group, oxygen as acceptor) inhibitor that interferes with the action of monoamine oxidase (EC 1.4.3.4).
EC 3.1.1.8 (cholinesterase) inhibitor
An EC 3.1.1.* (carboxylic ester hydrolase) inhibitor that interferes with the action of cholinesterase (EC 3.1.1.8).
EC 4.6.1.2 (guanylate cyclase) inhibitor
An EC 4.6.* (P1O lyase) inhibitor that interferes with the action of enzyme guanylate cyclase (EC 4.6.1.2).
antimicrobial agent
A substance that kills or slows the growth of microorganisms, including bacteria, viruses, fungi and protozoans.
antimalarial
A drug used in the treatment of malaria. Antimalarials are usually classified on the basis of their action against Plasmodia at different stages in their life cycle in the human.
Application(s): acid-base indicator
An acid or base which exhibits a colour change on neutralization by the basic or acidic titrant at or near the equivalence point of a titration.
fluorochrome
A fluorescent dye used to stain biological specimens.
antidepressant
Antidepressants are mood-stimulating drugs used primarily in the treatment of affective disorders and related conditions.
cardioprotective agent
Any protective agent that is able to prevent damage to the heart.
histological dye
A dye used in microscopic or electron microscopic examination of cells and tissues to give contrast and to highlight particular features of interest, such as nuclei and cytoplasm.
neuroprotective agent
Any compound that can be used for the treatment of neurodegenerative disorders.
physical tracer
A physical tracer is one that is attached by physical means to the object being traced.
antimalarial
A drug used in the treatment of malaria. Antimalarials are usually classified on the basis of their action against Plasmodia at different stages in their life cycle in the human.
