Which corticosteroid is commonly administered via an inhaler for asthma treatment?

Fluticasone is commonly administered via an inhaler for asthma treatment because it is a long-acting corticosteroid specifically designed for inhalation. It works by reducing inflammation in the airways, which helps prevent asthma attacks and improve airflow. The inhalation route allows the medication to be delivered directly to the lungs, providing localized treatment with a favorable safety profile.

In contrast, other corticosteroids like prednisone and methylprednisolone are typically used in systemic treatments for severe asthma exacerbations but are not preferred for routine management due to their potential systemic side effects. Budesonide is also an inhaled corticosteroid and could have been a plausible choice; however, fluticasone is often more commonly associated with the treatment of asthma in inhaler form in many clinical practices.
