Insomnia patients self-administered triazolam or placebo, finding triazolam improved sleep quality and reduced sleep onset latency. Placebo preference decreased when competing with triazolam, but increased when it was the sole option.

Area of Science:

  • Behavioral Pharmacology
  • Sleep Medicine
  • Clinical Psychology

Background:

  • Insomnia is a prevalent sleep disorder affecting millions worldwide.
  • Understanding patient choices in hypnotic self-administration is crucial for treatment optimization.
  • Triazolam is a short-acting benzodiazepine hypnotic used for insomnia.

Purpose of the Study:

  • To investigate self-administration patterns of triazolam and placebo in individuals with insomnia.
  • To assess the impact of choice conditions (single vs. forced) on hypnotic selection.
  • To evaluate the objective and subjective effects of triazolam on sleep parameters and mood.

Main Methods:

  • Twenty-four adults with insomnia (21-50 years) participated in a controlled study.
  • Participants underwent single-choice (placebo or triazolam) and forced-choice (placebo vs. triazolam) self-administration paradigms.

  • Sleep parameters were objectively measured, and mood was assessed using the Profile of Mood States (POMS) vigor scale.

    • Main Results:

    • Triazolam self-administration rates were similar across single and forced-choice conditions (77-86%).
    • Placebo selection was higher when it was the only option (80%) compared to when competing with triazolam (low rate).
    • Triazolam significantly increased total sleep time, reduced sleep latency, and decreased wake after sleep onset compared to placebo.

    Conclusions:

    • Patients with insomnia self-administer triazolam effectively, with choice paradigms influencing placebo selection.
    • Triazolam demonstrates significant hypnotic efficacy, improving sleep continuity and onset.
    • Choosing to take a capsule, regardless of type, was associated with improved pre-sleep vigor.
