Description
Curator's Comment: http://www.mdpoison.com/media/SOP/mdpoisoncom/healthcareprofessionals/antidote-facts/Methylene%20Blue%20Antidote%20Facts.pdf | https://clinicaltrials.gov/ct2/show/NCT01797978 | https://www.pharmgkb.org/pathway/PA165980834

Methylene blue, also known as methylthioninium chloride, is a medication from WHO's list of essential medicines. Upon administration, methylene blue is converted to leukomethylene blue by erythrocyte methemoblobin reductase in the presence of NADPH. Leukomethylene blue than reduces methemoglobin to oxyhemoglobin, thus restoring oxygen carrying capacity of the blood. Methylene blue is also used as a dye for various diagnostic procedures, for treatment of ifosfamide toxicity and for in vitro staining. Historically, it was used as a photosensitizer for photodynamic therapy for topical treatment of dermatologic or mucocutaneous infections, as an antidote for cyanide poisoning, but these applications are no longer approved. Methylene blue is investigated in clinical trials for treatment of septic shock and Alzheimer's disease.

Sample Use Guides

In Vivo Use Guide
Main route of adminitration is intravenous, 1-2 mg/kg by slow IV injection. Inject slowly over several minutes (usually 3–10 minutes). Historically was also administered orally, but oral preparations are no longer commercially available in US. As a photosensitizer is administered topically. For a diagnostic purposes is administered by local instillation or injection.
Route of Administration: Other
In Vitro Use Guide
Suspension of erytrocytes from acid/citrate/dextrose-treated blood were incubabed on air with 0.5M M-sodium nitrite solution in isoosmotic saline. The erytrocytes were separated by centrifugation, washed, and incubated at pH 7.4 and 37°C with 10 mM glucose and 10 uM Methylene Blue. Samples were taken at defined intervals and hemolysed with 10 vol of ice-cold water, after that the content of mehtemoglobin, hemoglobins intermediate and oxyhemoglobin was estimated.
