Abstract: | Thirty-two hospitalized patients with either endogenous (n = 15) or involutional (n = 17) depression were entered into a double blind study to compare the effectiveness and acceptability of viloxazine with amitriptyline. The severity of the depression was assessed before starting treatment and at day 7, 14 and 28 using the Hamilton Rating Scale. Spontaneously reported side effects were recorded. Patients received viloxazine 50 mg three times a day during the first week followed by 100 mg three times a day during the next three weeks or amitriptyline 25 mg three times a day during the first week followed by 50 mg three times a day during the following three weeks. Viloxazine and amitriptyline were equally effective in endogenous depression, but viloxazine was significantly more effective than amitriptyline in patients with involutional depression. Nausea and vomiting were the main side effect of viloxazine during early treatment necessitating the withdrawal of two patients. Anticholinergic side effects were reported during amitryptyline treatment, but were absent in patients on viloxazine. It is concluded that viloxazine is an effective antidepressant and particularly useful in the treatment of involutional depression. |
