Midazolam: sleep and performance studies in middle age.

A N Nicholson, B M Stone

    British Journal of Clinical Pharmacology
    |January 1, 1983
    PubMed
    Summary

    Midazolam improved sleep quality and duration in older adults, with no next-day performance impairment. This hypnotic may benefit shiftworkers needing to optimize shorter rest periods.

    Area of Science:

    • Pharmacology
    • Sleep Medicine
    • Gerontology

    Background:

    • Midazolam is a benzodiazepine with hypnotic properties.
    • Understanding its effects on sleep and next-day performance is crucial for therapeutic use.
    • Older adults may respond differently to sedative medications.

    Purpose of the Study:

    • To evaluate the dose-dependent effects of midazolam on sleep architecture and next-day cognitive performance in healthy older men.
    • To compare midazolam's effects with a placebo and an active control (brotizolam).

    Main Methods:

    • Double-blind, placebo-controlled study with an active control.
    • Six healthy adult males (47-53 years) participated.
    • Evaluated sleep parameters (latency, stages, efficiency) and next-day performance (Digit Symbol Substitution test).

    Main Results:

    • Midazolam (10-30 mg) reduced sleep onset latency and increased stage 2 sleep duration and percentage.
    • Higher doses (20-30 mg) showed similar improvements in total sleep time and sleep efficiency.
    • No significant residual cognitive impairment was observed 9 hours post-administration.

    Conclusions:

    • Midazolam effectively improves sleep quality in older adults without causing next-day performance deficits.
    • Its favorable sleep profile suggests potential utility as a hypnotic for shiftworkers with disrupted sleep patterns.
