Comparison of fluticasone propionate aqueous nasal spray and oral montelukast for the treatment of seasonal allergic rhinitis symptoms.

BACKGROUND: Few studies have directly compared the efficacy of intranasal corticosteroids with that of leukotriene receptor antagonists for the treatment of daytime and nighttime symptoms of seasonal allergic rhinitis (SAR). OBJECTIVE: To compare fluticasone propionate aqueous nasal spray, 200 microg daily, with oral montelukast, 10 mg daily, for the relief of SAR symptoms. METHODS: Patients with SAR 15 years or older were randomized to receive either fluticasone propionate (n = 367) or montelukast (n = 369) in this double-blind, double-dummy, parallel-group study. The primary efficacy measure was the mean change from baseline in daytime total nasal symptom scores (TNSSs) (the sum of 4 daytime individual nasal symptom scores INSSs] assessing nasal congestion, itching, rhinorrhea, and sneezing), averaged across weeks 1 and 2. Secondary efficacy measures included the 4 daytime INSSs, nighttime TNSSs (the sum of 3 nighttime INSSs assessing congestion on awakening, difficulty going to sleep, and nighttime awakenings), and the 3 nighttime INSSs averaged across weeks 1 and 2. RESULTS: Mean changes from baseline in daytime TNSSs (P < .001), all daytime INSSs (P < .001), nighttime TNSSs (P < .001), and all nighttime INSSs (P < or = .02) showed significant differences favoring fluticasone propionate over montelukast across 2 weeks of treatment. CONCLUSION: Compared with montelukast, fluticasone propionate provided significantly greater improvement in daytime and nighttime SAR symptoms.
