What is the primary action of corticosteroids in respiratory therapy?

Corticosteroids play a crucial role in respiratory therapy primarily due to their ability to reduce inflammation. In conditions such as asthma, chronic obstructive pulmonary disease (COPD), and various allergic reactions, inflammation in the airways can lead to increased mucus production, airway constriction, and difficulty breathing. By mitigating the inflammatory response, corticosteroids help to decrease swelling and irritation in the lungs and airways, which subsequently improves airflow and overall respiratory function.

Their anti-inflammatory properties are essential in providing relief from the symptoms associated with respiratory conditions, allowing patients to breathe more easily and reducing the frequency and severity of exacerbations. This mechanism of action differentiates corticosteroids from other treatments that may have different roles, such as promoting mucus production or altering blood vessel constriction. Understanding this primary action is critical for effective management and treatment of respiratory illnesses.
