      Drug Name Oxymetazoline (nasal) Methylene blue
      Mechanism Monoamine oxidase substrate Monoamine oxidase inhibitor
      Key Mechanism Factor 1
Factor Name Monoamine oxidase Structure Sequence
Protein Family Flavin monoamine oxidase family
Protein Function
Catalyzes the oxidative deamination of primary and some secondary amine such as neurotransmitters, with concomitant reduction of oxygen to hydrogen peroxide and has important functions in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues (PubMed:20493079, PubMed:8316221, PubMed:18391214, PubMed:24169519). Preferentially oxidizes serotonin (PubMed:20493079, PubMed:24169519). Also catalyzes the oxidative deamination of kynuramine to 3-(2-aminophenyl)-3-oxopropanal that can spontaneously condense to 4-hydroxyquinoline (By similarity).

      Mechanism Description
  • Decreased metabolism of Oxymetazoline (nasal) caused by Methylene blue mediated inhibition of non-CYP450 enzyme

Recommended Action
      Management Although data are limited, caution may be advisable when topical decongestants and vasoconstrictors are coadministered with MAOIs or other agents that possess MAOI activity (e.g., furazolidone, linezolid, methylene blue, procarbazine).
