Vilazodone (EMD-68,843, SB-659,746-A) is an antidepressant which is currently under development by Clinical Data for the treatment of major depressive disorder, and as of 2009 has completed two phase III clinical trials with positive results.[1] In the United States, an NDA was submitted on March 23rd, 2010 and was accepted by the FDA on May 21, 2010. Vilazodone is currently under standard review by the FDA with a PDUFA date of January 22, 2011, and if approved, will likely become available in the United States sometime next year.[2][3]


Vilazodone acts as a serotonin reuptake inhibitor (IC50 = 0.2 nM) and 5-HT1A receptor partial agonist (IC50 = 0.5 nM; IA = ~60-70%).[4][5] It has negligible affinity for other serotonin receptors such as 5-HT1D, 5-HT2A, and 5-HT2C.[4][5]

Efficacy and tolerability

According to an eight-week, randomized, double-blind, placebo-controlled trial, vilazodone was reported to elicit an antidepressant response after 1 week of treatment. After 8 weeks, subjects assigned to vilazodone experienced a significantly higher response rate than the group given placebo. At a dose of 40 mg per day, it's considered to be well tolerated and reported adverse effects ranged from mild to moderate in intensity; side effects included diarrhea, nausea, and somnolence.[6]
