Is AirDuo effective for asthma? AirDuo contains fluticasone and salmeterol. It combines a corticosteroid with a long-acting beta agonist. The dual mechanism targets inflammation and bronchospasm in persistent asthma. What studies show about its effectiveness Clinical trials found that AirDuo improved lung function and reduced exacerbations compared with fluticasone alone. Patients reported fewer symptoms and better asthma control scores. Why companies are challenging its patents Multiple generic manufacturers have filed Paragraph IV certifications against the AirDuo patent estate. These challenges focus on the formulation and delivery device rather than the active ingredients themselves.
