Which of the following is classified as an inhaled steroid?

Fluticasone is classified as an inhaled steroid, primarily used in the management of asthma and chronic obstructive pulmonary disease (COPD). Inhaled corticosteroids like fluticasone work by reducing inflammation within the airways, leading to decreased airway hyperresponsiveness and improved lung function. They are commonly prescribed for long-term control of respiratory conditions, helping to prevent symptoms and exacerbations.

In contrast, the other options listed serve different purposes or are administered via different routes. Prednisone and methylprednisolone are systemic corticosteroids, typically given orally or intravenously to treat a variety of inflammatory conditions but not specifically classified as inhaled steroids. Hydrocortisone, while also a steroid, is used for different medical conditions and is typically available in topical or systemic forms rather than inhalation. This distinction highlights the specific role of inhaled steroids in respiratory therapy, particularly for localized inflammation in the lungs.
