Mechanism of action of Trimipramine

Trimipramine (trye mip' ra meen) is a tricyclic antidepressant that is believed to act by enhancing serotonergic and dopaminergic neurotransmission. Like most tricyclic antidepressants, trimipramine is a weak inhibitor of serotonin, norepinephrine and dopamine reuptake, but also has direct antagonist activity for some serotonin and adrenergic receptors. Trimipramine has been shown to alleviate symptoms of depression, both in patients with neurotic or situation depression as well as those with major, endogenous depression. Trimipramine
