Use of zolpidem in over 75-year-old patients with sleep disorders and comorbidities.

Abstract

The aim of the present study was to evaluate the efficacy and safety of zolpidem in elderly subjects with disorders of sleep and comorbidities. The patients of this study had to present the following requirements: age over 70 years, reported disorders of sleep such as insomnia, and they had to be affected with diabetes and arterial hypertension. Patients presenting diseases that could interfere with sleep, i.e., anxiety, depression, panic attacks,alcohol abuse, some drugs were excluded from the study. All the jobs potentially causing insomnia carried out in the past from the patients were considered, too. A questionnaire of sleep was administered to all the patients (World Psychiatric Association: WPA, 1971).Insomnia, whenever present, was classified according to the criteria of the American Sleep Disorders (ASD) Society and the American Professional Sleep Society (APSS). The following scales were also administered: instrumental activities of daily living scale (IADL),activities of daily living (ADL), geriatric depression scale (GDS), cumulative illness rating scale (CIRS), short portable mental status questionnaire (SPMSQ), mini nutritional assessment (MNA), disease medical index (DMI), sleep questionnaire, social and environmental status. Two groups of patients were evaluated. Group A: 50 patients, 35 women and 15 men, mean age 78.9 years, with a history of insomnia, and Group B 30 patients, 20 women and 10 men, mean age 78.4 years, with onset of insomnia in the last three weeks. The two groups were further divided into three subgroups, diabetic, hypertensive and healthy patients. Zolpidem showed to be effective and well tolerated in both groups of patients.
