Abstract:
Aim and background: Chronic insomnia in elderly patients significantly affects their health and quality of life (QOL). Nocturia also worsens sleep condition. The aim of this study was to evaluate the improvement effects of quazepam, a long-term acting benzodiazepine, on insomnia and nocturia in elderly patients. Method: Forty-one elderly outpatients (mean age 77.1 ± 5.6 yr) suffering from chronic insomnia while on regular a short- or ultra-short-acting hypnotic treatment were enrolled. We prescribed 7.5-15 mg of quazepam, which was administered regularly by the subjects before bedtime. A questionnaire was used to compared changes in quality of sleep and frequency of nocturia for before treatment and at 2 and 4 weeks after initiation of treatment. QOL was also examined using the 36-item Short Form Health Survey of the Medical Outcomes Study (SF-36). Results: Thirty-seven subjects (90.2%) completed the study. All subscales of the sleep quality questionnaire improved significantly (p<0.001) after 2 weeks, as did the total scores (p<0.001) after 4 weeks. Frequency of nocturia decreased significantly from 3.6 ± 1.7 times to 1.5 ± 0.8 (p<0.001) and 1.2 ± 1.0 times (p<0.001) after 2 and 4 weeks, respectively. Every SF-36 subscale also showed significant improvement after 4 weeks. The total SF-36 scores of the group showing a decrease in the frequency of nocturia (>/= 2 times) improved significantly compared with that with a frequency of < 2 times (p=0.016). Conclusion: Quazepam significantly improves sleep, QOL and nocturia in elderly patients that respond poorly to short-acting or ultra-short-acting hypnotics.
