Abstract
1 Preliminary results of a double-blind placebo-controlled trial of mianserin and maprotiline carried out in 58 outpatients with primary depressive illness are reported.
2 Patients received six weeks' treatment with 30 to 90 mg mianserin, 75 to 225 mg maprotiline or one to three capsules of placebo, all medication being taken at night.
3 There were statistically significant improvements in each treatment group and a better response to mianserin than to placebo or maprotiline on the Hamilton Rating Scale for Depression, after one week's treatment.
4 Neither mianserin nor maprotiline was superior to placebo after two or four weeks' treatment and relatively few patients completed six weeks' treatment because of a generally unsatisfactory response.
5 Unwanted effects were not particularly troublesome, though mianserin and maprotiline caused more drowsiness and blurred vision than did placebo, while maptrotiline produced more constipation than either of the other two treatments.
6 The importance of placebo-controlled trials of antidepressants is emphasized and the precautions that should be taken when they are carried out in outpatients are described.
