Why are corticosteroids administered to patients with asthma?

Corticosteroids are administered to patients with asthma primarily to decrease airway swelling, which is crucial in managing this condition. Asthma is characterized by inflammation and narrowing of the airways, leading to symptoms such as wheezing, breathlessness, and chest tightness. By reducing inflammation, corticosteroids help to open up the airways, making breathing easier and improving overall pulmonary function.

The mechanism of corticosteroids involves targeting the inflammatory response that contributes to airway hyperreactivity. This action helps minimize the triggers that can lead to asthma exacerbations, such as allergens or irritants. Regular use of inhaled corticosteroids can significantly improve asthma control, decrease the frequency of asthma attacks, and lower the need for emergency interventions.

Other options related to respiratory health, such as promoting carbon dioxide reuptake or reducing respiratory infections, are not the primary roles of corticosteroids in asthma management. Additionally, while corticosteroids can have an indirect effect on mucus production by reducing inflammation, their main purpose is not to stop mucous production directly but rather to address the underlying inflammation that can lead to increased mucus and airway obstruction.
