Summary: | What is this summary about?
Inhaled corticosteroids (ICS) are a type of medication delivered via
an inhaler device that are commonly used in the treatment of asthma.
ICS can also be used to treat chronic obstructive pulmonary disease
(COPD), a progressive respiratory condition in which the lungs become
worse over time. However, unlike in asthma, ICS are only effective in a
small proportion of people with COPD.
ICS can cause significant side effects in people with COPD, including
pneumonia. Because of this, guidelines written by COPD experts
recommend that ICS should largely be prescribed to people with COPD
whose symptoms flare up frequently and become difficult to manage
(episodes known as exacerbations).
Despite this guidance, records collected from routine clinical practice suggest that many healthcare professionals prescribe
ICS to people with COPD who do not have frequent exacerbations, putting them at unnecessary risk of side effects.
The over-prescription of ICS in COPD may partly be due to the recent introduction of single-inhaler combination therapies,
which combine ICS with other medicines (bronchodilators). This ‘one inhaler for all’ approach is a concerning trend as it
goes against global COPD treatment guidelines, which recommend ICS use in only a small proportion of people.
This is a plain language summary of a review article originally published in the journal NPJ Primary Care Respiratory Medicine.
In this review, we investigate the benefits and risks of ICS use in COPD. Using data from both randomized controlled trials
(RCTs) and observational studies, we explain which people benefit from ICS use, and why health regulatory bodies have
concluded that ICS do not help people with COPD to live longer. Lastly, we provide practical guidance for doctors and
people with COPD regarding when ICS should be prescribed and when they should be withdrawn.
