Brotizolam as a pre-operative hypnotic
British Journal of Clinical Pharmacology
|January 1, 1983
Summary
Brotizolam effectively reduces preoperative anxiety and improves sleep. This hypnotic medication, particularly at 0.5 mg, demonstrated superior efficacy and tolerance compared to placebo and flunitrazepam.
Area of Science:
- Pharmacology
- Anesthesiology
Background:
- Preoperative anxiety and sleep disturbances are common concerns for surgical patients.
- Effective hypnotic agents are crucial for patient management before surgery.
Purpose of the Study:
- To evaluate the efficacy and tolerance of brotizolam as a preoperative hypnotic.
- To compare brotizolam with placebo and flunitrazepam for preoperative sedation.
Main Methods:
- Two double-blind, randomized parallel group studies were conducted.
- Patients received brotizolam (0.25 mg and 0.5 mg), placebo, or flunitrazepam (2.0 mg).
- Efficacy and tolerance were assessed through subjective patient evaluations.
Main Results:
- Brotizolam (0.25 mg and 0.5 mg) was significantly superior to placebo in efficacy (73.0% and 88.0% vs. 40.0%).
- The 0.5 mg dose of brotizolam showed higher efficacy than the 0.25 mg dose and reduced anxiety.
- Brotizolam (0.5 mg) demonstrated comparable efficacy and tolerance to flunitrazepam (2.0 mg) but maintained sleep more effectively.
Conclusions:
- Brotizolam is an effective and well-tolerated preoperative hypnotic agent.
- A dosage range of 0.25-0.5 mg of brotizolam is recommended for preoperative use.
- Brotizolam offers an effective alternative for managing preoperative anxiety and sleep.
