What is the most effective long-term controller therapy for asthma?

• A. Systemic steroids only during exacerbations
• B. Inhaled corticosteroids
• C. Leukotriene inhibitors
• D. Oral antibiotics

Answer: (B)

The key idea is that controlling long-term asthma relies on reducing chronic airway inflammation. Inhaled corticosteroids deliver anti-inflammatory medication directly to the airways, dampening inflammatory cells, mucus production, edema, and airway hyperresponsiveness. Because of this, they consistently improve daily symptoms, decrease the frequency of exacerbations, improve lung function, and reduce the need for rescue bronchodilators, making them the most effective long-term controller therapy. Systemic steroids are powerful but used mainly during acute flares due to systemic side effects, so they’re not suited for daily long-term control. Leukotriene inhibitors can help some patients and are options for those who cannot use inhaled steroids or as add-ons, but they are generally less effective at preventing symptoms and exacerbations than inhaled corticosteroids. Oral antibiotics don’t address the underlying inflammation of asthma and are not a strategy for chronic control. So, regular inhaled corticosteroids remain the best choice for long-term asthma control because they target the underlying airway inflammation that drives symptoms and exacerbations.
