Trintellix is a prescription medication used to treat major depressive disorder (MDD), a common mental health condition characterized by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in daily activities. Formerly known as Brintellix, it was approved by the U.S. Food and Drug Administration (FDA) in 2013 and is manufactured by Takeda Pharmaceuticals.

Trintellix works by targeting multiple brain receptors involved in regulating mood and emotions. Unlike traditional antidepressants, which mainly focus on serotonin reuptake inhibition, Trintellix is a multimodal agent. It acts as a serotonin transporter (SERT) inhibitor, but it also modulates several serotonin receptors (5-HT1A, 5-HT1B, 5-HT3, and 5-HT7) and the serotonin transporter (SERT).

Trintellix is indicated for the treatment of major depressive disorder in adults. It is not approved for use in children and adolescents. Physicians may prescribe Trintellix to patients who have not responded adequately to other antidepressant treatments or who have experienced intolerable side effects from other medications.

Trintellix offers several advantages over traditional antidepressants. Its multimodal action and unique mechanism make it a viable option for individuals who have not responded well to other treatments. Additionally, Trintellix’s side effect profile is generally favorable compared to some older antidepressants.
