Question: how does viibryd work in the brain?
Answer: The mechanism of the antidepressant effect of vilazodone is thought to be related to its enhancement of serotonergic activity in the CNS through selective inhibition of serotonin reuptake. Vilazodone binds with high affinity to the serotonin reuptake site but not to the norepinephrine or dopamine reuptake site.
