Clinical performance of fluticasone propionate nasal drops

The efficacy and safety of fluticasone propionate (FP) nasal drops were investigated in two multicentre, randomized, placebo-controlled trials. Patients received FP 400 microg once or twice daily for 12 weeks and then FP 400 microg once daily for a further 12 weeks. FP 400 microg significantly reduced polyp size and improved peak nasal inspiratory flow, rhinitis symptoms and sense of smell when administered twice daily. Significant reductions in polyp size were not achieved with once daily administration, but clinical benefits were observed for peak nasal inspiratory flow. Both dosing regimens were well tolerated, with an overall incidence of adverse events which was similar to placebo.
