Placebo-controlled, randomized, double-blind study evaluating the efficacy of fluticasone propionate nasal spray for the treatment of patients with hyposmia/anosmia

Abstract

In patients with anosmia/hyposmia partly caused by local inflammation, no further improvement in the olfactory threshold is achieved by continuing with a topical intranasal glucocorticoid after an initial combined topical and systemic glucocorticoid treatment.
