Methylene blue mechanism of action

ProvayBlue (methylene blue) injection - Mechanism of Action Methemoglobinemia is characterized by the blood's reduced ability to carry oxygen because of reduced levels of normal hemoglobin. Therefore, this condition presents as excessive replacement of hemoglobin with methemoglobin which leads to functional anemia and tissue hypoxia 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++) We found that two reactions are possible in a hemoglobinmethemoglobin-methylene blue system. The first is a direct oxidation of hemoglobin to methemoglobin by methylene blue; the second is a reduction of methemoglobin to hemoglobin which requires the reduced for Mechanism of Action. Methylene blue, in low concentrations, hastens the conversion of methemoglobin to hemoglobin; has opposite effect at high concentrations by converting ferrous ion of reduced hemoglobin to ferric ion to form methemoglobin; in cyanide toxicity, it combines with cyanide to form cyanmethemoglobin preventing the interference of cyanide with the cytochrome syste

  1. Doctors claim that methylene blue is a century-old blood pressure booster and was even used as an anti-malarial drug. It is mostly prescribed when oxygen saturation level among patients reduces
  2. Neurons are metabolically protected against degeneration using low-level methylene blue and near-infrared light interventions. Both of these novel interventions act by a cellular mechanism involving enhancement of the electron transport chain in mitochondria, which promotes energy metabolism and neuronal survival (Gonzalez-Lima et al., 2014)
  3. Methylene blue will most likely cause your urine or stools to appear blue or green in color. This is a normal side effect of the medication and will not cause any harm. However, this effect may cause unusual results with certain urine tests
  4. Methylene blue is commonly used as a treatment for methemoglobinemia, a condition in which the iron in the normal hemoglobin molecule is oxidized from the ferrous to the ferric state. Methylene.
  5. Methylene blue is the first line. It accelerates the enzymatic reduction of methemoglobin by NADPH-methemoglobin reductase and also reduces to leucomethylene blue that, in turn, reduces methemoglobin. This is contraindicated in patients with G6PD deficiency (can cause hemolysis). Hyperbaric O2 and exchange transfusions can also be utilized
