MeSH definition : An indirect sympathomimetic. Tyramine does not directly activate adrenergic receptors,
but it can serve as a substrate for adrenergic uptake systems and monoamine oxidase
so it prolongs the actions of adrenergic transmitters. It also provokes transmitter
release from adrenergic terminals. Tyramine may be a neurotransmitter in some invertebrate
nervous systems.; An indirect sympathomimetic that occurs naturally in cheese and other foods. Tyramine
does not directly activate adrenergic receptors, but it can serve as a substrate for
adrenergic uptake systems and MONOAMINE OXIDASE to prolong the actions of adrenergic
transmitters. It also provokes transmitter release from adrenergic terminals and may
be a neurotransmitter in some invertebrate nervous systems.;
