Drug data last refreshed 7h ago · AI intelligence enriched 1mo ago
PROVAYBLUE (methylene blue) is an intravenous solution that treats methemoglobinemia by converting ferric iron in methemoglobin back to normal hemoglobin through a non-enzymatic redox mechanism. The drug acts via leucomethylene blue (LMB), which is generated intracellularly and reduces metHb to functional hemoglobin. It is used in acute, life-threatening cases of methemoglobinemia caused by drug exposure or chemical ingestion.
Product is in peak lifecycle but faces imminent loss of exclusivity in January 2027, signaling shift from growth marketing to defensive strategies and smaller team focus.
non-enzymatic redox conversion of metHb to hemoglobin. In situ, methylene blue is first converted to leucomethylene blue (LMB) via NADPH reductase. It is the LMB molecule which then reduces the ferric iron of metHb to the ferrous state of normal hemoglobin.
