Randomised controlled study of sleep after nefazodone or paroxetine treatment in out-patients with depression

Year: 2002

Type: article

Study designs: Randomized Controlled Trial, Clinical Trial

Abstract: BACKGROUND: Sleep effects of antidepressants are important clinically and for elucidating mechanism of action: selective serotonin reuptake inhibitors disturb sleep and 5-HT(2) receptor-blocking compounds may enhance sleep quality. AIMS: To compare the objective and subjective effects on sleep of paroxetine and nefazodone in patients with moderate to severe depression. METHOD: Forty patients with depression were randomised to take paroxetine 20-40 mg/day or nefazodone 400-600 mg/day for 8 weeks. Objective and subjective quality of sleep and depression measures were assessed throughout. RESULTS: Nefazodone significantly increased objective sleep efficiency and total sleep time, and improved subjective sleep on days 3 and 10. Paroxetine decreased sleep efficiency early in treatment and some sleep disruption remained at week 8. Paroxetine but not nefazodone produced marked suppression of rapid eye movement (REM) sleep. CONCLUSIONS: Nefazodone improves sleep in early treatment compared with paroxetine in patients with moderate to severe depression. These effects are seen within the first 2 weeks of treatment and diminish thereafter.
