Fluticasone Propionate Diskus Inhaler is an inhaled corticosteroid used as maintenance or controller treatment for asthma. Inhaled corticosteroids, such as fluticasone, are the most effective anti-inflammatory medications for asthma. Inhaled corticosteroids reduce asthma symptoms, increase lung function, reduce airway hyperresponsiveness, improve quality of life, and reduce risk of asthma-related exacerbations or hospitalizations. The Global Initiative for Asthma (GINA) endorses using inhaled fluticasone for asthma.
