Lorazepam as night sedation and premedication: a comparison with diazepam

Fifty healthy female patients scheduled for surgery were randomly allocated into two groups in a double‐blind study. One group received lorazepam 2·5 mg orally at 2200 h on the evening before surgery as night sedation, and again at 0800 h on the morning before surgery as premedication. The second group received diazepam 10 mg orally at the same times.
