Mechanism of Action
Venlafaxine and its active metabolite O-desmethylvenlafaxine selectively inhibit the neuronal reuptake of serotonin, norepinephrine and to a lesser extent dopamine. It has minimal affinity for muscarinic, histamine, or ?1-adrenergic receptors. It appears to be as effective as standard antidepressants but w/ a lower incidence of anticholinergic, sedative and CV side effects.
