Other anti-inflammatory uses of intranasal corticosteroids in upper respiratory inflammatory diseases.

Topical corticosteroids are an effective treatment for nasal polyposis and other conditions associated with rhinitis. There is evidence that asthma, otitis media with effusion, and acute sinusitis may all benefit from such therapy. Fluticasone propionate (FP) drops have been shown to reduce polyp size, and to improve nasal inspiratory flow, while avoiding the side-effects of, for example, topical betamethasone therapy. In small children with allergic rhinitis, fluticasone propionate aqueous nasal spray (FPANS) has been shown to be significantly more effective than ketotifen in relieving night and daytime symptoms, and nasal blockage. There is also preliminary evidence of efficacy in obstructive sleep apnoea and acute sinusitis. The advent of FP, with its low propensity to cause systemic side-effects, makes it possible to use topical corticosteroid therapy safely for prolonged periods to treat many inflammatory diseases of the upper respiratory tract.
