Trazodone (trade names Desyrel, Molipaxin, Trittico, Thombran, Trialodine) is a psychoactive compound with sedative, anxiolytic, and antidepressant properties. The various manufacturers claim that the antidepressant activity becomes active in the first week of therapy. Trazodone has less prominent anticholinergic (dry mouth, constipation, tachycardia) and adrenolytic (hypotension, male sexual problems) side effects than most tricyclic antidepressants.
Although trazodone is often conceived to be a tricyclic antidepressant it belongs to the family of tetracyclic antidepressants.
