Mechanism of action of Tranylcypromine

Tranylcypromine (tran" il sip' roe meen) is an antidepressant that acts through inhibition of monoamine oxidase, an enzyme that inactivates several neurotransmitter amines such as norepinephrine and serotonin. By inhibition of catabolism of serotonin and norepinephrine, tranylcypromine increases brain levels of these neurotransmitters, actions which probably underlie its antidepressant effects.
