- Background
Methylene blue is an oxidation-reduction agent. The intravenous form of methylene blue is approved by the FDA for the treatment of pediatric and adult patients with acquired methemoglobinemia. Historically, it has been widely used in Africa to treat malaria, but now it disappeared when chloroquine (CQ) and other drugs entered the market. Its use as an urinary tract antiseptic has also been investigated.
Methylthioninium chloride (INN, or methylene blue, proposed trade name Rember) is an investigational drug being developed by the University of Aberdeen and TauRx Therapeutics that has been shown in early clinical trials to be an inhibitor of Tau protein aggregation. The drug is of potential interest for the treatment of patients with Alzheimer's disease.

Pharmacology
- Indication
Indicated for the treatment of pediatric and adult patients with acquired methemoglobinemia.
Other clinical applications of methylene blue include improvement of hypotension associated with various clinical states, an antiseptic in urinary tract infections, treatment of hypoxia and hyperdynamic circulation in cirrhosis of liver and severe hepatopulmonary syndrome, and treatment of ifofosamide induced neurotoxicity.

- Mechanism of action
- Main mechanism of action involves inhibition of nitric oxide synthase and guanylate cyclase.
- In Alzheimers Disease: a mechanistic study found that methylene blue oxidizes cysteine sulfhydryl groups on tau to keep tau monomeric. One preclinical treatment study in tauopathy mice reported anti-inflammatory or neuroprotective effects mediated by the Nrf2/antioxidant response element (ARE); another reported insoluble tau reduction and a learning and memory benefit when given early.
- In Methemoglobinemia: Methylene Blue acts by reacting within RBC to form leukomethylene blue, which is a reducing agent of oxidized hemoglobin converting the ferric ion (fe+++) back to its oxygen-carrying ferrous state(fe++).
- As antimalarial agent: Methylene Blue, a specific inhibitor of P.falciparum glutathione reductase has the potential to reverse CQ resistance and it prevents the polymerization of haem into haemozoin similar to 4-amino-quinoline antimalarials.
- For ifosfamide induced neurotoxicity: Methylene blue functions as an alternate electron acceptor. It acts to reverse the NADH inhibition caused by gluconeogenesis in the liver while blocking the transformation of chloroethylamine into chloroacetaldehyde. In addition, it inhibits various amine oxidase activities, which also prevents the formation of chloroacetaldehyde.

- Volume of distribution
10 mg/kg (in rats).
- Protein binding
Methylene blue was reported to bind strongly to rabbit plasma (71–77% of bound drug).
- Metabolism
Following distribution into tissues, rapidly reduced to leukomethylene blue (leucomethylthioninium chloride). Metabolism to leucomethylene blue may be less efficient in neonates than in older individuals.
- Route of elimination
Excreted in urine and bile. About 75% of an oral dose excreted in urine, primarily as stabilized colorless leukomethylene blue.
- Half-life
5–6.5 hours (after IV dose).
- Clearance
3.0 ± 0.7 L/min.

interactions in your software1,2-Benzodiazepine The risk or severity of CNS depression can be increased when Methylene blue is combined with 1,2-Benzodiazepine. Abacavir Abacavir may decrease the excretion rate of Methylene blue which could result in a higher serum level. Abaloparatide Methylene blue may increase the orthostatic hypotensive activities of Abaloparatide. Abametapir The serum concentration of Methylene blue can be increased when it is combined with Abametapir. Abatacept The metabolism of Methylene blue can be increased when combined with Abatacept. - Food Interactions
