The impact of antidepressants on sleep and anxiety: a comparative study of fluoxetine and dothiepin using the Leeds Sleep Evaluation Questionnaire.
Fluoxetine (20 mg) was compared to dothiepin (150 mg) in a multicentre, prospective, double blind, randomised clinical trial involving 125 patients with major depression treated for an initial phase of 6 weeks and then followed up for a further 6 months. There was no difference in the efficacy of the two drugs based on the results of established rating scales (MADRS, HAM-D, BPRS). The impact of both drugs on sleep measured using the Leeds Sleep Evaluation Questionnaire showed no significant differences between treatments, however drowsiness and disturbed sleep were reported more frequently as side effects with dothiepin. Symptoms of anxiety responded equally well to both treatments. The short term and long term tolerability of dothiepin was inferior to that of fluoxetine. The place of dothiepin in treatment should be reassessed in the light of its anticholinergic adverse event profile, particularly in the elderly. Copyright 2000 John Wiley & Sons, Ltd.
