Effects of zopiclone on quality of life in insomnia.

All of the components of quality of life can be altered in insomniacs because of sleep disorders themselves but theoretically also in consequence to side effects from hypnotic agents. The presented international study, carried out with a multicentre, randomised and double-blind design, investigated zopiclone effects on quality of life in insomniac patients as compared to placebo. A total of 458 patients completed the study, 231 receiving zopiclone 7.5 mg and 227 receiving placebo, with mean treatment durations of 48 and 44 days. Sleep parameters and quality of life, measured with extensive and validated scales, were assessed at baseline and at 14, 28 and 56 days after admission. Zopiclone showed hypnotic efficacy and significantly greater improvement of quality of life as compared to placebo, both at 14 days and at endpoint.
