Mechanism of Action
The mechanism of the antidepressant effect of vortioxetine is thought to be related to its enhancement of serotonergic activity in the CNS through inhibition of the reuptake of serotonin (5-HT). It also has several other activities including 5-HT3 receptor antagonism and 5-HT1A receptor agonism. The contribution of these activities to vortioxetine’s antidepressant effect has not been established.
Trintellix Indications
Indications
Major depressive disorder (MDD).
Trintellix Dosage and Administration

Concomitant strong CYP2D6 inhibitors: reduce vortioxetine dose by ½; increase to original dose when inhibitor is discontinued. Concomitant strong CYP inducers for >14 days: consider increasing vortioxetine dose up to max 3× original dose; reduce to original dose within 14 days when inducer is discontinued.

Trintellix Interactions
Interactions
See Contraindications. Increased risk of serotonin syndrome with other serotonergic drugs (eg, other SNRIs, SSRIs, triptans, TCAs, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, St. John's Wort) or with drugs that impair serotonin metabolism (eg, MAOIs, linezolid, IV methylene blue). Potentiated by strong CYP2D6 inhibitors (eg, bupropion, fluoxetine, paroxetine, quinidine); see Adult. Antagonized by strong CYP inducers (eg, rifampin, carbamazepine, phenytoin); see Adult. Increased risk of bleeding with antiplatelets or anticoagulants (eg, NSAIDs, aspirin, clopidogrel, heparin, warfarin); monitor. May potentiate other highly protein bound drugs (eg, warfarin). May cause false (+) results in urine enzyme immunoassays for methadone; consider alternative chromatographic methods.
