Effective dose range of mometasone furoate nasal spray in the treatment of acute rhinosinusitis

Ann Allergy Asthma Immunol. 2002 Sep;89(3):271-8. doi: 10.1016/S1081-1206(10)61954-0.


Background: Mometasone furoate nasal spray (MFNS) 400 microg, twice daily, as adjunctive treatment with oral antibiotic significantly improved symptoms of recurrent rhinosinusitis.

Objective: To evaluate the effectiveness and safety of MFNS 200 microg, twice daily, and 400 microg, twice daily, compared with placebo as adjunctive treatment with oral antibiotic for acute rhinosinusitis.

Methods: In this multicenter, double-blind, placebo-controlled study, 967 outpatients with computed tomographic scan-confirmed moderate to severe rhinosinusitis received amoxicillin/clavulanate potassium (Augmentin, GlaxoSmithKline, Research Triangle Park, NC) 875 mg, twice daily, for 21 days with adjunctive twice daily MFNS 200 microg, MFNS 400 microg, or placebo nasal spray. Patients recorded scores of six rhinosinusitis symptoms and any adverse events twice daily. Pre- and postcosyntropin-stimulation plasma cortisol levels were measured in a subset of patients at selected study sites.

Results: Treatment with MFNS 200 microg or 400 microg, twice daily, produced significantly greater improvements in total symptoms score (primary efficacy variable) day 1 to day 15 average (50% and 51%, respectively) than placebo (44%, P < or = 0.017). Both doses of MFNS produced significant total symptoms score improvement over placebo by day 4, and maintained efficacy over the entire 21-day study. Relief of individual symptoms showed a similar pattern. Both doses of MFNS were well tolerated, and adverse events were similar to that of placebo. Cosyntropin stimulation showed no evidence of hypothalamic-pituitary-adrenal axis suppression.

Conclusions: As adjunctive therapy to oral antibiotic treatment, MFNS at doses of 200 microg or 400 microg, twice daily, was well tolerated and significantly more effective in reducing the symptoms of rhinosinusitis than antibiotic therapy alone.
