Introduction: Clinical trials have provided some evidence of a favorable effect of inhaled corticosteroids on the frequency of exacerbations and on the quality of life of patients with chronic obstructive pulmonary disease (COPD). In contrast, ICS have little or no impact on lung function decline and on mortality.
State of the art: Inhaled corticosteroids are recommended only in a minority of COPD patients, those with severe disease and repeated exacerbations and probably those with the COPD and asthma overlap syndrome. However, surveys indicate that these drugs are inappropriately prescribed in a large population of patients with COPD. Overtreatment with inhaled corticosteroids exposes these patients to an increased risk of potentially severe side-effects such as pneumonia, osteoporosis, and oropharyngeal candidiasis. Moreover, it represents a major waste of health-care spending.
Conclusion: Primary care physicians as well as pulmonologists should be better aware of the benefits as well as the side-effects and costs of inhaled corticosteroids.
