A comparative clinical trial of mianserin (Norval) and amitriptyline in the treatment of depression in general practice.

A double-blind controlled comparative trial of mianserin (Norval) and amitriptyline was conducted in general practice. Fifty-one patients were treated with amitriptyline and fifty-five with mianserin. The dosage for the first week was 25 mg t.d.s. for amitriptyline and 10 mg t.d.s. for mianserin, increasing to 50 mg t.d.s. and 20 mg t.d.s. respectively for the subsequent three weeks. Both drugs proved equally effective in relieving the symptoms of primary depression but mianserin showed a reduced incidence of side-effects which was statistically significant.
