Comparison of inhaled corticosteroid combined with theophylline and double‐dose inhaled corticosteroid in moderate to severe asthma

Abstract

Both ICS combined with SRT and double-dose ICS had the same effect on asthma control, improving symptoms and ameliorating lung function. Both therapies had similar anti-airway inflammatory effects and therapeutic safety. Combining SRT with ICS may allow a reduction in ICS dose when treating asthma.
