Final answer:
Fluticasone (inhaled corticosteroid) is usually classified as a "symptom controller" in asthma as it helps in long-term control by preventing asthma attacks and managing daily symptoms.
Step-by-step explanation:
Fluticasone, classified as an inhaled corticosteroid, is indeed a key component in long-term control medications for asthma. It acts as a symptom controller by addressing the underlying inflammation and swelling in the airways, thereby preventing asthma attacks and managing symptoms on a daily basis. Unlike quick-relief medications that offer immediate relief during an acute attack, fluticasone provides sustained control, making it effective for the ongoing management of asthma. By reducing airway inflammation, fluticasone contributes to improved respiratory function and helps individuals maintain better control over their asthma symptoms, promoting overall respiratory health and quality of life.
