title: Brotizolam as a pre-operative hypnotic.
abstract: Efficacy of and tolerance to brotizolam when used as a preoperative hypnotic were studied in two double-blind, randomised parallel group studies. Brotizolam (0.25 and 0.50 mg) was superior to placebo. Efficacy was assessed as good-to-satisfactory in 73.0% of patients with 0.25 mg and in 88.0% with 0.5 mg. A similar assessment was reached in 40.0% of patients with placebo. Brotizolam 0.5 mg was superior to 0.25 mg, and with the higher dose subjective assessments of anxiety were reduced. Efficacy of tolerance to 0.5 mg brotizolam and 2.0 mg flunitrazepam were compared, and both drugs were found to be effective and well tolerated. Brotizolam maintained sleep throughout the night more effectively than flunitrazepam. A dose range of 0.25-0.5 mg brotizolam is recommended as a pre-operative hypnotic.
