Abstract
Two hundred and fifty female patients about to undergo elective gynecological surgery were randomly allocated to a single oral dose of either 5, 15, 30 mg Org 3770, placebo or 10 mg diazepam the evening before operation. Assessment of sleep quality next morning using self-rated questionnaires showed that both Org 3770 and diazepam were significantly better than placebo in enhancing sleep. A dose-response effect was seen with Org 3770, 15 mg seeming optimal. Assessment of presurgery anxiety, again using self-rated questinnaires, showed that 15 mg Org 3770 and 10 mg diazepam were significantly more effective than placebo at reducing anxiety. None of the medications produced any troublesome side effects nor did they have an effect on blood pressure.
