Olanzapine increases slow-wave sleep: evidence for blockade of central 5-HT(2C) receptors in vivo.
BACKGROUND: The study aimed to determine the effects of the atypical antipsychotic agent, olanzapine, on the polysomnogram in healthy subjects. We predicted that olanzapine, via serotonin(2C) (5-HT(2C)) receptor blockade, would increase slow-wave sleep (SWS). METHODS: We studied the effects of single evening doses of olanzapine (5 mg and 10 mg orally) on the polysomnogram of 9 healthy male volunteers, using a placebo-controlled, double-blind, cross-over design. RESULTS: Compared to placebo, t...Expand abstract
