Common sedatives linked to increased risk of pneumonia in people with Alzheimer's disease
"An increased risk of pneumonia is an important finding to consider in treatment of patients with Alzheimer disease," writes Dr. Heidi Taipale, Kuopio Research Centre of Geriatric Care, University of Eastern Finland, Kuopio, Finland, with coauthors. "Benzodiazepines and Z-drugs are frequently prescribed for this population, and long-term use is typical. Pneumonia often leads to admission to hospital, and patients with dementia are at increased risk of death related to pneumonia." Dementia, of which 60%-70% of cases are Alzheimer disease, is a risk factor for pneumonia, and many people with dementia are prescribed benzodiazepines and non- benzodiazepines (called Z-drugs), both of which have sedative effects. To determine if there is a link between these drugs and pneumonia, Finnish researchers looked at data from national registries on 49 484 adults living in the community diagnosed with Alzheimer disease between 2005 and 2011 in Finland.
