Efficacy of Barrier Treatment for Patients with Seasonal Allergic Rhinitis
Study Objective: To evaluate the efficacy of PrevaLin as an add-on to standard therapy for seasonal· allergic rhinitis (AR) caused by sensitization to wormwood pollen. Study Design: This was an open-label, prospective, randomized, comparative, parallel-group study. Materials and Methods: A total of 49 patients with moderate-to-severe or severe seasonal AR caused by sensitization to wormwood pollen were followed-up for 30 days. All patients received intranasal corticosteroids (CS) in combination with a non-sedative antihistamine agent. Thirty of these patients additionally received Prevalin 4 times a day. Results: Adding Prevalin to a combination pharmaceutical regimen led to a more rapid and effective resolution of AR symptoms and maintained pharmacological remission with a lower amount of background therapy. Conclusion: Prevalin usage can be considered an etiology- and pathogenesis-oriented treatment for moderate-to-severe or severe seasonal AR.
