Background: Asthma is a chronic inflammatory condition of lung airways resulting in episodic airflow obstruction causing considerable morbidity in paediatric population. The main objective of the study was to find out whether addition of long acting beta agonists to steroids provides better asthma control.Methods: This randomized controlled trial study was performed in children aged 6-15 years of age, with clinically stable and moderate persistent asthma.Results: The findings of this study indicate SABA use in Budesonide/formoterol group patients was significantly less compared to budesonide group patients (1.5±1.1 v/s 2.13±0.9, p-value 0.01). Both groups experienced decrease in night time symptoms and acute exacerbations however there was no significant difference between the two groups in these variables.Conclusions: This study showed addition of LABA to inhaled steroids in moderate persistent asthma provided better asthma control and LABA is mainly recommended to be used as add-on therapy for patients whose asthma is not controlled on low to high doses of inhaled corticosteroids.
