    Buspirone, taken three times daily, did not negatively impact daytime alertness or performance in chronic insomnia patients. It also did not alter the alertness effects of flurazepam or triazolam.

    Area of Science:

    • Pharmacology
    • Sleep Medicine
    • Clinical Psychology

    Background:

    • Chronic insomnia significantly impacts daily functioning and quality of life.
    • Buspirone is an anxiolytic medication with potential effects on sleep and daytime function.
    • Understanding the impact of buspirone on objective measures of daytime alertness is crucial for patient management.

    Purpose of the Study:

    • To evaluate the effects of buspirone, administered three times daily, on sleep patterns and daytime function in individuals with chronic insomnia.
    • To assess whether buspirone alters the daytime alertness effects of concomitant benzodiazepine use (flurazepam or triazolam).

    Main Methods:

    • A placebo-controlled, double-blind, crossover study design was employed.
    • Twelve volunteers with chronic insomnia participated in the study.

  • Objective measures of daytime wakefulness and performance, including the Multiple Sleep Latency Test, were utilized.

    • Main Results:

    • Buspirone, when administered alone, did not impair objective measures of daytime wakefulness or performance.
    • Alertness was reduced the day after flurazepam administration, but not after triazolam; buspirone did not modify these effects.
    • Buspirone did not influence the results of the Multiple Sleep Latency Test, indicating no change in daytime alertness.

    Conclusions:

    • Buspirone appears to be safe regarding daytime alertness and performance in patients with chronic insomnia.
    • The combination of buspirone with flurazepam or triazolam does not exacerbate the sedative effects of these benzodiazepines on daytime alertness.
    • Buspirone does not negatively affect objective measures of daytime alertness in individuals suffering from chronic insomnia.
