Which of the following is a common route of administration for corticosteroids in respiratory therapy?

Inhalation is a common route of administration for corticosteroids in respiratory therapy because it allows for direct delivery of the medication to the lungs. This method enhances the drug's effectiveness while minimizing systemic side effects often associated with oral or intravenous routes. Inhaled corticosteroids are particularly beneficial for managing chronic respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD) because they target the inflamed airways directly, reducing inflammation and improving lung function. This localized delivery is crucial in respiratory therapy, where rapid and efficient control of airway inflammation is needed.

While oral and intravenous administration are valid methods for delivering corticosteroids, they typically lead to broader systemic effects and potential side effects. Subcutaneous administration is not commonly used for corticosteroids in this context, making inhalation the most advantageous route for this purpose.
