An update on the use of inhaled therapy in COPD.

Inhaled corticosteroids represent the mainstay of pharmacological treatment for reversible airways disease, and traditionally have had widespread use in non-reversible chronic obstructive pulmonary disease (COPD). However, use in this group may expose patients to an increased risk of pneumonia, without significant benefit to symptoms or exacerbation frequency. Here we provide a guide to the use of inhaled therapy in COPD for the general physician. © Royal College of Physicians 2018. All rights reserved.
