Acta Psychiatr Scand 1996: 93: 184–190. © Munksgaard 1996. A total of 115 elderly patients (60–85 years of age) with DSM III diagnosis of major depressive episode were randomly assigned to 6 weeks of treatment with either mirtazapine, 15–45 mg/day, or amitriptyline, 30–90 mg/day. Efficacy was assessed biweekly, using tbe Hamilton Rating Scale for Depression (HRSD) and Montgomery and Åsberg Depression Rating Scale (MADRS) as primary outcome variables. The treatment with both drugs resulted in a similar reduction of total HRDS and MADRS scores, with no statistically significant differences between treatment groups at any assessment point or at endpoint. Statistically significant differences favouring amitriptyline were present according to CGI‐Global Improvement Scale at endpoint, HRDS cognitive disturbance factor at weeks 2, 4 and 6 and endpoint and retardation factor at week 6. Adverse events were reported by a similar number of patients in both treatment groups. Additional research is needed to assess further the efficacy and tolerability of mirtazapine among elderly depressed patients.
