Aptazapine (CGS-7525A) is a tetracyclic antidepressant (TeCA) which was assayed in clinical trials for the treatment of depression in the 1980s but was never marketed. It is a potent α2-adrenergic receptor antagonist with ~10x the strength of the related compound mianserin and has also been shown to act as a 5-HT2 receptor antagonist and H1 receptor inverse agonist while having no significant effects on the reuptake of serotonin or norepinephrine.
