Methylene blue has multiple indications for use, but recently it has been shown to be useful in treating refractory hypotension. Methylene blue and its analogues are known to have antibacterial activity, although few studies have determined their MICs which is the gold standard used to measure and compare antimicrobial activity. The inhibition by methylene blue of multiple amine oxidase activities also prevents formation of the neurotoxic chloroacetaldehyde from ifosfamide-derived chloroethyl amine. Tex Heart Inst J.
