Aptazapine had noradrenergic and specific serotonergic activity. It antagonised \u03b12 adrenergic receptors approximately 10 times more effectively than mianserin, antagonised 5-HT2 receptors, agonised H1 receptors, and did not affect reuptake of serotonin or norepinephrine. Although Aptazapine reached clinical trials, it was never marketed."}]
