Chronic obstructive pulmonary disease is characterised by progressive symptoms of productive cough, breathlessness, wheeze and exacerbations. Airway obstruction is detected by quality assured spirometry, and is defined as a Forced Expired Volume in one second / Forced Vital Capacity ratio <0.7. Inhaled therapy is the most effective treatment solution, with bronchodilators and inhaled steroids helping to improve symptoms, quality of life and lung function, while reducing risk of exacerbations. Bronchodilators are available as both monotherapy and as dual combination therapy. Inhaled steroids can be added to inhaled long-acting bronchodilators, but are not without significant complications, including pneumonia. Therefore, careful assessment of the phenotype of a patient with chronic obstructive pulmonary disease must be given before commencing any therapy that contains inhaled steroid and other treatments, such as flu vaccination, smoking cessation and pulmonary rehabilitation should be given due consideration.
