Which medication is classified as a corticosteroid and used for respiratory issues?

Advair is classified as a corticosteroid medication, specifically used to manage respiratory issues. It combines a corticosteroid (fluticasone) with a long-acting bronchodilator (salmeterol) to help reduce inflammation and improve airflow in patients with conditions such as asthma and chronic obstructive pulmonary disease (COPD). The corticosteroid component plays a crucial role in decreasing airway inflammation, which is essential for treating respiratory issues effectively.

Other options do not fit this classification: Ventolin is a bronchodilator used for quick relief of asthma symptoms, while Zyrtec and Claritin are antihistamines used to relieve allergy symptoms but are not used for respiratory conditions in the context of airway inflammation or similar issues addressed by corticosteroids.
