A double blind comparison is reported of a new tetracyclic antidepressant, maprotiline, with amitriptyline and placebo in psychiatric outpatients. Amitriptyline was significantly more effective than placebo in its global effect on depression. Maprotiline emerged as neither inferior to amitriptyline nor superior to placebo. Methodological difficulties prevented an adequate assessment of the anxiolytic activity of maprotiline.
