title: Effects of fluoxetine and dothiepin on 24-hour activity in depressed patients.
abstract: Psychomotor retardation is a recognised symptom of depressive illness, and improvement in psychomotor function is associated with the amelioration of the severity of depressive symptoms. Actigraphy permits behavioural activity to be continuously assessed, allowing changes in psychomotor activity to be monitored over time. A randomised, parallel-group, double-blind study was conducted in 14 general practice patients with a diagnosis of major depression. This pilot study was designed to investigate the utility of actigraphy in this patient population and to investigate possible differences between fluoxetine and dothiepin in their effects on 24-hour behavioural activity monitored for the first 10 days of treatment. Patients taking dothiepin (75 mg rising to 150 mg in the second week, nocte) were found to be significantly (p < 0.05) less active over the course of the day compared to those treated with fluoxetine (20 mg, mane). This lower level of behavioural activity in the dothiepin group was particularly noticeable in the early morning (06:00-08:00 h).
