Flashcards
Short-Acting Beta Agonist (SABA)
Short-Acting Beta Agonist (SABA)
A type of asthma medication that provides fast relief from symptoms like wheezing and shortness of breath.
Inhaled Corticosteroid (ICS)
Inhaled Corticosteroid (ICS)
A type of asthma medication that reduces inflammation in the airways and helps prevent asthma attacks.
Formoterol
Formoterol
A long-acting beta agonist, similar to SABA, but works for a longer time. It is often combined with ICS for asthma management.

Study Notes
Asthma Reliever Therapy Comparison
-
Objective: To compare short-acting beta-agonists (SABA) alone with SABA combined with inhaled corticosteroids (ICS) and with formoterol (fast-onset, long-acting beta-agonist) combined with ICS for asthma treatment.
-
Data Sources: MEDLINE, Embase, and CENTRAL databases were searched from January 1, 2020 to September 27, 2024, including all languages.
-
Study Selection: Randomized clinical trials evaluating SABA alone, ICS with formoterol, and ICS with SABA (using combined or separate inhalers) were selected.
-
Study Population: 50,496 adult and pediatric patients; mean age, 41.0 years; 40% male.
-
Primary Outcomes:
-
Asthma symptom control (measured using a 5-item Asthma Control Questionnaire, with lower scores indicating better control, minimum important difference: 0.5 points).
-
Asthma-related quality of life (measured using an Asthma Quality of Life Questionnaire, with higher scores indicating better quality of life, minimum important difference: 0.5 points).
-
Risk of severe exacerbations.
-
Risk of serious adverse events.
-
Key Findings:
-
ICS-formoterol and ICS-SABA vs. SABA alone: Both combinations demonstrate high certainty for fewer severe exacerbations compared to SABA alone. The risk reduction was 10.3% and 4.7%, respectively, with high confidence.
-
Both combinations also show high certainty for improved asthma control compared to SABA alone. Asthma control improvements were 4.1% and 5.4% respectively.
-
ICS-formoterol vs. ICS-SABA: An indirect comparison suggests ICS-formoterol is associated with fewer severe exacerbations (5.5% risk reduction, moderate certainty) compared to ICS-SABA.
-
Serious Adverse Events: Neither ICS-formoterol nor ICS-SABA demonstrated an increased risk of serious adverse events in comparison to SABA alone, with high certainty for formoterol combination, and moderate certainty for ICS-SABA.
-
Conclusion: Inhaled corticosteroid-containing relievers (formoterol and SABA combinations) are associated with reduced asthma exacerbations, improved asthma control compared to SABA alone.
