azelastine/fluticasone (aze/flu) nasal spray on symptom control, nasal mediators and nasal hyperresponsiveness in allergic rhinitis (ar)

Conditions: Allergic Rhinitis; House Dust Mite Allergy

Summary: comparative analysis of the efficacy of intranasal mp29-02 (a novel formulation of azelastine and fp) has already been conducted in patients with moderate-to-severe seasonal ar. the combination formulation appeared to be superior in these patients with better symptomatic relief. however, objective analysis of the effect of this treatment on nasal mediators and/or nasal hyperreactivity has not yet been performed and would help in understanding the additional benefit of the combination treatment over monotherapy with nasal corticosteroids.
