Older adults with COPD more frequently use benzodiazepines

A popular class of drugs commonly used to treat sleep and mood symptoms continues to be frequently prescribed despite being known to have potentially life-threatening side effects.

Previous studies have linked benzodiazepines - a medication class that may be used in chronic obstructive pulmonary disease (COPD) to treat symptoms of insomnia, depression, anxiety and shortness of breath - with adverse outcomes, but until now there has been little information on how frequently it's prescribed or who is using it.

COPD, also known as emphysema or chronic bronchitis, is most commonly caused by smoking in North America and is estimated to affect 5 to10 per cent of the Canadian population. American Thoracic Society-European Respiratory Society guidelines recommend that benzodiazepines be avoided in these patients because of potential respiratory-related side-effects.

Dr. Nicholas Vozoris is the lead author of a study published this week in Drugs and Aging looking at the scope of benzodiazepine use in the older adult COPD population to determine just how many people are using the drug.

"I see a large number of COPD patients taking this medication class to help relieve disease-related symptoms like insomnia, depression and anxiety," said Dr. Vozoris, a respirologist at St. Michael's Hospital. "But considering the potential respiratory side-effects, and the well-documented neurocognitive side effects like memory loss, decreased alertness, falls and increased risk of motor vehicle accidents, the high frequency of benzodiazepine use in COPD is very concerning."

Dr. Vozoris and colleagues looked at more than 100,000 adults 66 years and older with COPD in Ontario between 2004 and 2009 to see how many new benzodiazepines were dispensed and the severity of each patients' COPD while on the drug.
