What is the primary role of inhaled corticosteroids in asthma management?

Inhaled corticosteroids play a crucial role in asthma management by primarily targeting airway inflammation. These medications work by reducing the underlying inflammatory process that contributes to asthma symptoms and exacerbations. By decreasing inflammation, inhaled corticosteroids help improve airway function and sensitivity, which translates to better control of asthma symptoms over time.

Their preventive nature is significant; they are not intended for immediate relief during an asthma attack, but rather are used regularly to manage asthma and significantly lower the frequency and severity of exacerbations. While promoting mucus clearance and enhancing lung volume, increasing respiratory rate, or improving oxygen saturation are important aspects of overall respiratory health, they are secondary benefits that do not encapsulate the primary purpose of inhaled corticosteroids in the context of asthma management.
