Noxiptiline (brand names Agedal, Elronon, Nogedal), is a tricyclic antidepressant (TCA) that was introduced in Europe in the 1970s for the treatment of depression. In a double-blind comparison of noxiptiline and amitriptyline in hospitalized patients with primary depressive illness for 3-6 weeks there were no significant differences, but noxiptiline had a faster onset of action. A comparison with imipramine also showed no difference in therapeutic efficacy. As regards adverse effects, noxiptiline seemed to cause more mental symptoms, such as delirium. In one study in 44 patients, 9 developed delirium, there were mild manic symptoms in 6, dry mouth in 21, disturbed micturition in 2. and difficulty in accommodation in 3.
