Abstract
Objective: To evaluate the safety and efficacy of eszopiclone 2 mg in elderly patients (aged 64-86 years) with chronic insomnia. Methods: This was a randomized, double-blind, placebo-controlled 2-week study. Patients meeting DSM-IV criteria for primary insomnia and screening polysomnography criteria (wakefulness after sleep onset [WASO] ≥ 20 min and latency to persistent sleep a 20 min) were randomized to 2 weeks of nightly treatment with eszopiclone 2 mg (n = 136) or placebo (n = 128). Efficacy was assessed using polysomnography (Nights 1, 2, 13, and 14) and patient reports (Nights 1-14); safety was assessed using adverse events, clinical labs, physical examination, and vital signs. The mean of all efficacy results during the double-blind period was used for the efficacy analysis. Results: Results indicated that eszopiclone was associated with significantly shorter sleep onset, less WASO, higher sleep efficiency, more total sleep time, and greater patient-reported quality and depth of sleep scores than placebo (p < 0.05 for all) with a trend in patient-reported morning sleepiness (p = 0.07). Other measures of daytime functioning (ability to function, daytime alertness, and sense of well-being) were not significantly different between the two treatment groups. Among patients who napped, eszopiclone patients reported fewer naps (p = 0.03) and less cumulative naptime (median: 98 min placebo, 70 min eszopiclone, p = 0.07). Unpleasant taste, dry mouth, somnolence, and dizziness were higher in the eszopiclone group (12.5%, 8.8%, 6.6%, and 6.6%, respectively) than in the placebo group (0%, 1.6%, 5.5%, and 1.6%, respectively). Conclusion: In this study, eszopiclone was well tolerated and produced significant improvements in both polysomnographic and patient-reported measures of sleep maintenance, sleep induction, and sleep duration in elderly patients with chronic primary insomnia.
