Efficacy and Safety of Olopatadine/Mometasone Combination Nasal Spray in Patients With Seasonal Allergic Rhinitis

Combining an intranasal antihistamine with an intranasal corticosteroid for the treatment of allergic rhinitis (AR) may provide improved symptom relief over monotherapy treatment. GSP301 nasal spray is a fixed-dose combination of the antihistamine olopatadine hydrochloride and the corticosteroid mometasone furoate. The efficacy and safety of GSP301 were evaluated in a large, phase 3 seasonal AR (SAR) study.
