Mechanism of Action

Methylene Blue: How It Works

Methylene blue is a phenothiazine dye. It has an osmotic effect which helps determine cellular respiration. It accepts electrons and supports the electron transport chain. This leads to a boost in ATP synthesis. It also helps regulate iron levels, reduce oxidative stress, and improve nerve functioning.

This dye can pass through the blood-brain barrier. When exposed to light of certain wavelengths, it acts as a photosensitizer and kills cancer cells via apoptosis or necrosis. Methylene blue also stops monoamine oxidase activity. This limits the breakdown of dopamine, serotonin, and norepinephrine in pre-synaptic neurons; making it an antidepressant drug.

In addition, it has anti-inflammatory effects. It regulates inflammatory genes such as IL-1ß, IL-6, and TNF-alpha. It also limits neutrophil uptake to inflammation sites. When used in sepsis-induced shock or vasoplegia, it acts as a vasopressor agent due to its effect on vascular smooth muscles.

In conclusion, methylene blue is a useful medication that aids in different fields such as neurology, oncology, psychiatry, and critical care medicine.
