According to an article by Medscape, regular use of aspirin may result in a 50% reduction in emphysema progression in elderly COPD patients.

Results of the study included:

  • Progression of percent emphysema was slower among regular aspirin users compared to non-aspirin users
  • Results were similar in ever-smokers and for doses of 81 mg and 300-325 mg. A greater magnitude effect was seen among participants with airflow limitations.
  • No association was found between aspirin use and change in lung function.
