Dymista is a fixed-dose combination inhaler that contains azelastine and fluticasone propionate. It is used for the maintenance treatment of asthma and allergic rhinitis in adults and children. The azelastine component acts as an antihistamine that blocks h1 receptors to reduce inflammation and nasal symptoms. The fluticasone propionate component is a synthetic corticosteroid that suppresses immune cell activity and airway inflammation. Together they provide bronchodilation and decrease swelling in the airways to improve breathing. The medication delivers these drugs directly to the respiratory tract where they are absorbed into the airway tissues to exert their therapeutic effects.

Dymista is a combination nasal spray that contains azelastine and fluticasone propionate used to treat allergic rhinitis. Azelastine is an antihistamine that blocks h1 receptors to reduce histamine mediated symptoms. Fluticasone propionate is a synthetic corticosteroid that suppresses inflammation by inhibiting the transcription of inflammatory cytokines. The synergy of these agents addresses both immediate allergic response and underlying nasal inflammation. By modulating histamine activity and dampening immune mediated inflammation the spray improves nasal airflow and reduces sneezing and congestion. This dual mechanism provides comprehensive symptomatic relief in a single application.
