Sleep, morning alertness and quality of life in subjects treated with zopiclone and in good sleepers. Study comparing 167 patients and 381 good sleepers.
From 20,000 households regularly surveyed by a national survey institute (Sofres), two groups were selected and questioned (using a 23-item questionnaire) about sleep vigilance and quality of life. The first group was composed of insomniacs using zopiclone for the last 12 months and no other CNS treatments (167 subjects). The second group was composed of 381 "good sleepers" selected as having no or occasionally one sleep disturbance in the last 12 months. No difference was found between the two groups in average total sleep time. Sleep disturbances were statistically equal in the two groups except for difficulties in initiating sleep which is more present for zopiclone users (13% vs 3%). Vigilance was mostly comparable in both groups.Five aspects of quality of life explored by the questionnaires (the professional, relational and sentimental, domestic, leisure and safety aspects) appeared to be comparable in the two groups.
