Values are Ki (nM), unless otherwise noted. The smaller the value, the more strongly the drug binds to the site.

Setiptiline acts as a norepinephrine reuptake inhibitor, α2-adrenergic receptor antagonist, and serotonin receptor antagonist, likely at the 5-HT2 subtypes,[citation needed] as well as an H1 receptor inverse agonist/antihistamine.[additional citation(s) needed]

Chemistry

Setiptiline has a tetracyclic structure and is a close analogue of mianserin and mirtazapine, with setiptiline being delta(13b,4a),4a-carba-mianserin, and mirtazapine being 6-azamianserin.
