Sampling MethodProbability Sample
Study Population

Primary insomniacs meeting DSM-IV criteria, ages 23-70 yrs. old, were recruited from public advisement for a double-blind placebo controlled study. Participants were in good general health as determined by a physical exam and laboratory tests. The Structured Clinical Interview for DSM Disorders (SCID) and the Hamilton Depression Scale were used to exclude those with psychiatric disorders, drug, and alcohol dependence. To confirm the absence of illicit drugs, participants underwent a urine drug screen. Additionally, participants had a screening sleep efficiency of \<85% on an 8-hr nocturnal polysomnogram (NPSG) and had no primary sleep disorders. Pregnant or lactating females were excluded from study participation.

You may qualify if:

  • age 21-70 yrs
  • non-pregnant females who agree to standard birth control for 12 months and males
  • two of the following chronic insomnia complaints: \>30 min sleep latency, \< 6 hrs sleep, or nonrestorative sleep.
  • meet DSM-IV criteria for primary insomnia

You may not qualify if:

  • any acute or unstable illness: conditions making it unsafe for the subject to participate, conditions with a potential to disturb sleep (i.e. acute pain, respiratory infection), and conditions which could interact with the pharmacokinetics or pharmacodynamics of zolpidem.
  • chronic illnesses: renal failure, liver disease, seizures, and dementing illnesses.
  • current psychiatric diseases: alcohol or substance abuse, depression, and schizophrenia.
  • a history of alcohol or substance abuse within the past two years.
  • a prestudy positive urine drug screen
  • consuming \>14 standard (1oz) alcoholic drinks per week
  • caffeine consumption \>300 mg/day
  • smoking during the night (11pm-7am).
  • medications including: anxiolytics, hypnotics. both prescription and OTC, (except in the chronic zolpidem group), antidepressants, anticonvulsants, sedating H1 antihistamines (non-sedating second generation H1 antihistamines are allowed), systemic steroids, respiratory stimulants and decongestants, prescription and OTC stimulants, prescription and OTC diet aids, herbal preparations, and narcotic analgesics. All medications and doses will be documented.
  • sleep disordered breathing (SDB) defined as \>10 apnea-hypopneas events per hour of sleep time or any other primary sleep (e.g., restless legs syndrome) or circadian disorder.
