What is the primary action of corticosteroids in the treatment of respiratory disorders?

Corticosteroids play a key role in the management of respiratory disorders primarily due to their ability to reduce inflammation. In conditions such as asthma and chronic obstructive pulmonary disease (COPD), inflammation of the airways can lead to symptoms such as wheezing, coughing, and difficulty breathing. By decreasing the inflammatory response, corticosteroids help to lower the production of inflammatory mediators, reduce airway swelling, and improve overall airway function.

This anti-inflammatory effect is essential for controlling exacerbations and maintaining better long-term respiratory health. Patients using corticosteroids may experience reduced frequency and severity of asthma attacks or COPD flare-ups, leading to improved quality of life.

While bronchodilation, mucus thinning, and stimulating the cough reflex are also important aspects of managing respiratory conditions, these effects are primarily associated with other classes of medications. For example, bronchodilators are specifically designed to relax bronchial smooth muscle, allowing for wider airways and improved airflow.
