Efficacy of Combined Antidepressant Therapy in Resistant Neurotic Disorder

Abstract

A 35-year-old woman with persistent affective and phobic symptoms responded dramatically to a combination of isocarboxazid and amitriptyline, and this improvement was maintained over the next three-and-a-half years. Isocarboxazid was replaced by placebo, using double-blind procedure. The change to placebo was accompanied by a marked increase in anxiety and depressive symptoms, which resolved when active isocarboxazid was reintroduced. It is suggested that combined antidepressant therapy still has a place in the treatment of resistant neurotic disorder.
