Residual effects of flurazepam and brotizolam on psychomotor performance.

Residual effects of brotizolam (0.25 mg) and flurazepam (30 mg) were studied in healthy young adults. Performance and subjective assessments were observed from 7 to 8 h after overnight ingestion, and effects were compared with that of placebo. Visuo-motor coordination, visuo-mental processing time, visuo-motor reaction time and reading errors were not impaired with brotizolam. There were residual effects with 30 mg flurazepam. Visuo-motor coordination, visuo-mental processing time, visuo-motor reaction time, and reading errors were impaired compared with placebo and 0.25 mg brotizolam. Subjective assessments of performance correlated with measured performance. There was a decrease with flurazepam (visuo-motor coordination and visuo-mental processing time) compared with placebo.
