Pulse intravenous clomipramine as an alternative antidepressant treatment to ECT. A pilot study

Abstract

Background and Objectives: The aim of the study was to examine the antidepressant effect of a single pulse dose of intravenous clomipramine (200 mg i.v.) followed by oral administration as an alternative method to electroconvulsive therapy. Methods: Twenty-one inpatients (8 male, 13 female) with major depression were included. Depression severity was measured by Montgomery Asberg Rating Scale (MADRS) and Clinical Global Impression severity scale (CGI-S) before the pulse dose and 1 week after. The day after the pulse dose, the patient was medicated with 75 mg of oral clomipramine and from day two with 150 mg clomipramine daily. Results: The MADRS score dropped with 39% ± 22% and the CGI score with 28% ± 19% in one week. The improvement of the MADRS score after one week was 13.1 (C.I.9.5-17.0). CGI-ratings dropped from a mean of 5.5 (SD 1.2) to 3.9 (SD 1.1), an improvement of 28% ± 19%.(C.I. 1.0-2.1). Both improvements were significant (p<000.1). Conclusions: Single pulse dose clomipramine administration ameliorates depressive symptoms, and may be an alternative to ECT.
