Abstract
The efficacy and safety of maprotiline (Ludiomil) was compared to imipramine in patients with manic-depressive illness, depressed type (DSM [Diagnostic and Statistical Manual of Mental Disorders] II 296.2). Patients [341] from 16 different centers entered this 4-wk double-blind controlled trial, with 171 in the maprotiline and 170 in the imipramine group. Efficacy measurements included the Hamilton Depression Scale, the Self-Rating Depression Scale, and the Investigator''s Overall Assessment of Effectiveness. Tolerability was monitored by collection of treatment-emergent signs and symptoms (TESS), blood pressure and pulse measurements, EcG, and EEG. Dosage was fixed for the 1st wk at 50 mg t.i.d. [3 times daily] and thereafter could be varied between 50 and 300 mg daily. Clinically and statistically significant reductions in symptomatology were noted in both drug groups for most efficacy parameters at each visit during therapy. Comparison between the drug groups revealed no difference in terms of the scales utilized. A trend toward fewer TESS in the maprotiline group was noted, especially for the side effects nausea, nervousness, and increased sweating.
