A double-blind comparative trial with mianserin and amitriptyline in outpatients with major depressive disorders

Abstract

1 A double-blind trial with parallel treatment groups was conducted to compare the safety and efficacy of mianserin with amitriptyline. 2 This was a six week trial with weekly visits. Measurements at each visit included: 21 item Hamilton Depression (HAMD) Scale. Clinical Global Impression (CGI) Scale and Treatment Emergent Symptom Scale (TESS). 3 Mianserin and amitriptyline were comparable with respect to efficacy. 4 More adverse experiences were reported by amitriptyline patients. The predominant amitriptyline adverse experiences were of the anticholinergic type; the predominant mianserin adverse experience was drowsiness/fatigue. 5 The Efficacy Index (EI), a scale combining efficacy and adverse experiences, clearly demonstrated the superiority of mianserin over amitriptyline.
