Responsiveness of observer rating scales by analysis of number of days until improvement in patients with major depression.

Several well-known observer scales, including the Hamilton Depression Scale (HAM-D), Montgomery-Asberg Scale (MADRS), Major Depression Rating Scale (MDS), Melancholia Scale (MES), and Inventory for Depressive Symptomatology (IDS) used for measuring severity of depressive states have been compared by their responsiveness in an open trial including patients treated with a combination of citalopram and mianserin. The patients fulfilled the Diagnostic and Statistical Manual (DSM)-IV criteria for major depressive episode, and all scored 18 or more on the HAM-D before treatment. Onset of antidepressant action was defined as an improvement of rating scale scores of 25% or more of pre-treatment scores. A response to treatment was defined as a reduction of 50% or more on the pre-treatment scores. The results showed that the number of treatment days until improvement was 11 to 13 with no difference between the scales. The days until response were between 18 and 21 with no difference between the scales. In conclusion, the depression scales were found to be equal in their ability to detect changes in depressive symptoms during treatment. The mean of days to response was 19 for the combination of citalopram and mianserin. This is similar to the response for the combination of fluoxetine and pinolol.

Morning fluoxetine plus evening mianserin versus morning fluoxetine plus evening placebo in the acute treatment of major depression.

In a randomized clinical study the combination of fluoxetine 20 mg daily and mianserin 30 mg daily was compared to fluoxetine 20 mg daily and a mianserin placebo. In total, 34 patients with major depression were randomized, of whom 16 received fluoxetine plus mianserin; 18 patients received fluoxetine plus placebo. Of these patients, 69% completed the planned trial of six weeks in the fluoxetine plus mianserin group while 61% completed in the fluoxetine plus placebo group. In the efficacy analysis (excluding dropouts from the first two weeks of treatment) the combination of fluoxetine and mianserin was superior to fluoxetine and placebo both in observer ratings of depression and in quality of life ratings. However, in the intention-to-treat analysis this difference was not statistically significant. No major side effects were reported. After four weeks of treatment headache was most often seen in the fluoxetine and mianserin combination, while sweating was most often seen in the fluoxetine plus placebo group. No pharmacokinetic interaction in terms of fluoxetine plasma levels was found in the mianserin-treated patients.
