The place of inhaled corticosteroids in chronic obstructive pulmonary disease

SUMMARYThe role of systemic corticosteroids in the treatment of exacerbations of chronic obstructive pulmonary disease (COPD) is well established. However, despite being frequently prescribed for the treatment of COPD, the clinical utility of inhaled corticosteroids (ICS) is less clearly defined.While individual clinical and epidemiological studies have yielded conflicting results, meta-analysis of available data suggests that ICS may reduce the frequency and severity of exacerbations, the number of hospitalisations and the mortality rate, as well as yielding improvements in lung function and health-related quality of life (HRQL) in some subgroups of COPD patients. More recently, clinical trials evaluating the effect of combination therapy with ICS and long-acting β2-agonists (LABA) have shown significant effects on the prevention of exacerbations and HRQL. Emerging data are expected to clarify the role of ICS in the management of patients with COPD of different severities as well as the place of treatmen...
