Current guidelines for chronic obstructive pulmonary disease (COPD) recommend a stepwise approach to inhaled pharmacotherapy.¹ The assessment of COPD is based on severity of airflow limitation (spirometric grades 1–4), as well as symptom burden and risk of exacerbations (groups A–D). Symptoms and exacerbations are the main factors that drive treatment decisions. The greatest health-care burden is associated with frequent exacerbations of COPD—ie, in patients in groups C and D.
