Mechanism of action

Viibryd (vilazodone) blocks the reuptake of serotonin at the serotonin transporter and also has partial agonist activity at the 5-HT1A receptor. This dual mechanism increases synaptic serotonin availability while the 5-HT1A agonism may enhance antidepressant efficacy and potentially reduce sexual dysfunction compared to traditional SSRIs.
