Amitifadine is a novel, serotonin-preferring triple reuptake inhibitor with a relative potency to inhibit serotonin (5-HT), norepinephrine (NE), and dopamine (DA) reuptake. Amitifadine is most potent against the 5-HT transporter. Amitifadine did not cause marked inhibition of major CYP450 isoenzymes, and had a good safety margin at the hERG ion channel. Initial clinical trial in patients with severe major depression demonstrated significant antidepressant activity with amitifadine, including attenuating symptoms of anhedonia, and a tolerability profile that was comparable to placebo. Amitifadine did not increase any sexual side effects as well as weight gain. It’s in phase III clinical trial for the treatment of Major depressive disorder.

Route of Administration: Oral

In Vitro Use Guide

DOV 216,303 inhibits [(3)H]NE, [(3)H]5-HT, and [(3)H]DA uptake to the corresponding human recombinant transporters (expressed in HEK 293 cells) with IC(50) values of approximately 20, 14, and 78 nM, respectively. DOV 216,303 is active in tests predictive of antidepressant activity including the mouse forced swim test and reversal of tetrabenazine-induced ptosis and locomotor depression.
