Mometasone furoate. A review of its intranasal use in allergic rhinitis.

UNLABELLED: Mometasone furoate is a synthetic corticosteroid which has been evaluated for intranasal use in the treatment of adults and children with allergic rhinitis. In several large, well-controlled clinical trials, mometasone furoate 200 micrograms administered once daily as an aqueous intranasal spray was significantly more effective than placebo in controlling the symptoms associated with moderate to severe seasonal or perennial allergic rhinitis. Mometasone furoate was as effective as twice-daily beclomethasone dipropionate or once-daily fluticasone propionate in the treatment of perennial allergic rhinitis, and was as effective as twice-daily beclomethasone dipropionate and slightly more effective than once-daily oral loratadine in the treatment of seasonal allergic rhinitis. Mometasone furoate was also as effective as twice-daily beclomethasone dipropionate or once-daily budesonide, and significantly more effective than placebo in the prophylaxis of seasonal allergic rhinitis. The onset of action of mometasone furoate was approximately 7 hours in patients with seasonal allergic rhinitis. Mometasone furoate was as well tolerated as beclomethasone dipropionate, fluticasone propionate and budesonide in clinical trials, with an overall incidence of adverse events similar to placebo. Adverse events were generally mild to moderate and of limited duration. The most common adverse events associated with mometasone furoate therapy were nasal irritation and/or burning, headache, epistaxis and pharyngitis. Intranasal or oral mometasone furoate had no detectable effect on hypothalamic-pituitary-adrenal axis function in studies of < or = 1 year in duration.

CONCLUSIONS: Mometasone furoate is a well tolerated intranasal corticosteroid with minimal systemic activity and an onset of action of < or = 7 hours. It is effective in the prophylaxis and treatment of seasonal allergic rhinitis and the treatment of perennial allergic rhinitis in patients with moderate to severe symptoms.
