Mechanism of action

Tricyclic antidepressants (TCAs) inhibit the reuptake transporters for norepinephrine and serotonin, prolonging the presence of these neurotransmitters in the synaptic cleft. This increased neurotransmitter availability enhances monoaminergic signaling in the brain. TCAs also have anticholinergic and antihistamine properties that contribute to their therapeutic and adverse effects.
