Tyramine (/ˈtaɪrəmiːn/TY-rə-meen) (also spelled tyramin), also known under several other names,[note 1] is a naturally occurring trace amine derived from the amino acid tyrosine.[4] Tyramine acts as a catecholamine releasing agent. Notably, it is unable to cross the blood-brain barrier, resulting in only non-psychoactive peripheral sympathomimetic effects following ingestion. A hypertensive crisis can result, however, from ingestion of tyramine-rich foods in conjunction with the use of monoamine oxidase inhibitors (MAOIs).
