Vortioxetine: a New Treatment for Major Depressive Disorder.

Vortioxetine is a structurally novel medication that has recently been approved for treatment of major depressive disorder (MDD). This medication is a serotonin reuptake inhibitor that also has a number of other potentially relevant effects on serotoninergic receptors, which may differentiate the drug's effects from those of current first-line antidepressants, such as selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs).
