Abstract
Objective
To summarize the principal findings of all available studies that have evaluated the use of inhaled corticosteroids (ICS) on an intermittent or as-needed basis as an add-on therapy to short-acting β2-agonists (SABAs) or fast-acting β2-agonists (FABAs) in pediatric asthmatic patients. Studies could either include or omit the use of ICS during stable periods of the disease.
Data sources
Electronic databases MEDLINE, EMBASE, CINAHL, SCOPUS, and the Cochrane Database of Systematic Reviews from inception to February 2021.
Study selections
Relevant articles in the literature published by February 2021.
Results
Of 294 references identified, 14 studies were included. The use of ICS on an intermittent or as-needed basis (as an add-on therapy to SABAs) has been shown to be more effective than treatment with SABA alone and to be similarly or less effective compared to regular daily ICS administration. Furthermore, strategies involving increasing the dose of ICS only when needed (as an add-on therapy to formoterol, a FABA) and keeping it low during stable stages of the disease (i.e. single maintenance and reliever therapy, SMART) have been shown to be similarly or more effective than comparators.
Conclusion
The use of ICS on an intermittent or as-needed basis as an add-on therapy to SABAs or FABAs, with or without ICS use during stable periods of the disease in pediatric asthmatic patients, encompasses several effective treatment strategies.
