		Gene Name		MAOB
		Uniprot ID		AOFB_HUMAN
		KEGG Pathway		hsa:4129
		Protein Family		Flavin monoamine oxidase family
		Protein Function		Catalyzes the oxidative deamination of primary and some secondary amines such as neurotransmitters, and exogenous amines including the tertiary amine, neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), with concomitant reduction of oxygen to hydrogen peroxide and participates in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues (PubMed:11134050, PubMed:8665924, PubMed:8316221, PubMed:11049757, PubMed:20493079). Preferentially degrades benzylamine and phenylethylamine (PubMed:11134050, PubMed:8665924, PubMed:8316221, PubMed:11049757, PubMed:20493079). Click to Show/Hide
Mechanism Description		Additive hypotensive effects by the combination of Nitroprusside and Rasagiline

Recommended Action
Management		Caution is advised during coadministration of MAOIs and other medications with hypotensive effects, especially during the first few weeks of treatment. Close monitoring for development of hypotension is recommended. Ambulatory patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.
