Vortioxetine

Dosage form: tablets (5mg, 10mg, 20 mg)
Drug class: Miscellaneous antidepressants

Usage of Vortioxetine

Vortioxetine (Trintellix) is an antidepressant used to treat major depressive disorder (MDD) in adults. Vortioxetine is thought to work by increasing levels of serotonin in the brain, serotonin is a neurotransmitter. Vortioxetine's mechanism of action (MOA) is thought to be related to the inhibition of the reuptake of serotonin (5-HT), it has other activities, including 5-HT3 receptor antagonism and 5-HT1A receptor agonism, but it is unclear whether these have an antidepressant effect.

Vortioxetine is classified as a miscellaneous antidepressant, although some class vortioxetine it as a SSRI (selective serotonin reuptake inhibitor) or a serotonin modulator.

Vortioxetine originally became an FDA-approved medicine on September 30, 2013, under the brand name Brintellix. In May 2016, Takeda Pharmaceuticals U.S.A., Inc. and Lundbeck announced that Brintellix would be marketed in the United States under the new name Trintellix effective June 2016. The change comes after receiving reports of name confusion in the marketplace between Brintellix and the anti-blood-clotting therapy Brilinta (ticagrelor).

However, stopping the medicine may not be safe for you. Do not start or stop vortioxetine without asking your doctor.

Warnings

Suicidal Thoughts and Behaviors in Adolescents and Young Adults: Some young people have thoughts about suicide when first taking an antidepressant. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor, such as mood or behavior changes, anxiety, panic attacks, trouble sleeping, or if you feel impulsive, irritable, agitated, hostile, aggressive, restless, hyperactive (mentally or physically), more depressed, or have thoughts about suicide or hurting yourself.

Serotonin Syndrome: Increased risk when this medicine is used with other serotonergic agents, but there is also a risk when taken alone. Do not use vortioxetine if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, methylene blue injection, phenelzine, tranylcypromine, and others. After you stop taking vortioxetine, you must wait at least 21 days before you start taking an MAO inhibitor.

Increased Bleeding Risk: Vortioxetine can increase the risk of bleeding events, and using aspirin, nonsteroidal anti-inflammatory drugs, other antiplatelet drugs, warfarin, or other drugs that affect blood clotting may increase that bleeding risk.

Discontinuation Syndrome: Adverse reactions after discontinuation of serotonergic antidepressants, particularly after a sudden discontinuation of these medicines. Whenever possible, a gradual reduction in dosage rather than abrupt cessation is recommended.

Activation of Mania/Hypomania: There is an increased risk of mania or hypomania in patients who have bipolar disorder, so it is important to screen patients for bipolar disorder, mania, or hypomania before starting treatment with this medicine.

Angle Closure Glaucoma: Angle closure glaucoma has occurred in patients with untreated anatomically narrow angles treated with antidepressants.

Low blood sodium levels (Hyponatremia): Can occur when taking some types of antidepressants and may be a result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH). Elderly patients may be at greater risk of developing hyponatremia with a serotonergic antidepressant. Also, patients taking diuretics or otherwise volume-depleted can be at greater risk.

Sexual Dysfunction: Vortioxetine may cause symptoms of sexual dysfunction in males and females.
