Trintellix (vortioxetine) is a prescription antidepressant drug that is manufactured by Takeda Pharmaceuticals America, Inc. It is used to treat depression in adults 18 years of age and older. Trintellix was formerly known by the brand name Brintellix, but Takeda Pharmaceuticals changed its name to avoid confusion with a blood thinner named Brilinta. Trintellix (vortioxetine) is indicated by the U.S. Food and Drug Administration (FDA) for the treatment of major depressive disorder (MDD) in adults.
Trintellix increases serotonin concentrations in your brain by inhibiting its reuptake and also by activating or blocking certain serotonin receptors. Trintellix does not have a significant effect on dopamine or norepinephrine.
Because of Trintellix’s serotonergic activity, it is often classified as a selective serotonin reuptake inhibitor (SSRI). It is also classified as an atypical antidepressant or a serotonin receptor modulator.
