Adding montelukast to fluticasone propionate/salmeterol for control of asthma and seasonal allergic rhinitis

Abstract

Limited information exists comparing fluticasone propionate/salmeterol combination (FSC) versus montelukast (MON) in patients with coexistent asthma and allergic rhinitis. The purpose of this study was to compare the addition of MON to patients receiving FSC on asthma control while experiencing asthma and allergy symptoms. Additionally, the effect of fluticasone propionate aqueous nasal spray (FPANS) and MON were assessed in allergic rhinitis control. Symptomatic patients (n = 1385) with asthma and seasonal allergic rhinitis were randomized to receive FSC, 100/50 micrograms twice daily; FSC twice daily + FPANS, 200 micrograms once daily; FSC twice daily + MON, 10 mg once daily; or MON once daily for 4 weeks during the allergy pollen season. Patients recorded peak expiratory flow, rescue albuterol use, and asthma and rhinitis symptoms. No additional improvements in overall asthma control were seen when MON was added to FSC. Treatment with FSC produced significant (p < 0.001) improvements in all clinical and patient-reported measures versus MON. FSC + FPANS was superior to FSC + MON (p < or = 0.001) in improving daytime and nighttime total nasal symptom scores. Adverse events were similar. In patients with asthma and allergic rhinitis, adding MON to FSC provided no additional benefit in asthma control. FSC resulted in superior improvement in asthma control compared with MON. FPANS also provided superior nasal symptom control versus MON in allergic patients treated with FSC for asthma. Optimal disease control in patients with asthma and allergic rhinitis should be achieved by the most effective therapy directed toward each disease component.
