Pharmacological basis and scientific rationale underlying the targeted use of inhaled corticosteroid/long-acting β2-adrenergic agonist combinations in chronic obstructive pulmonary disease treatment
2015
Introduction: Chronic obstructive pulmonary disease (COPD) is a complex respiratory disorder, whose medical and socioeconomic burden as one of the main causes of morbidity and mortality is increasing worldwide. COPD pathophysiology includes chronic airway/lung inflammation and progressive airflow limitation. Therefore, anti-inflammatory and bronchodilator agents are key players in COPD treatment.Areas covered: This review article discusses the complementary molecular interactions connecting the respective mechanisms of action of inhaled corticosteroids (ICS) and long-acting β2-adrenergic agonists (LABAs). Moreover, attention is also focused on clinical trials, which have shown that ICS/LABA combinations are very effective in improving COPD symptoms and lung function, being also able to significantly reduce disease exacerbations.Expert opinion: In selected subgroups of COPD patients, ICS/LABA combinations represent a very useful therapeutic approach for this widespread chronic respiratory disease.
