Abstract
A randomized double blind placebo controlled cross‐over study comparing budesonide 400 μg and budesonide 800 μg daily in 59 patients is presented. Nasal obstruction was the predominant symptom and was subjectively and objectively improved by both doses of budesonide (P < 0.001). No significant difference was found between the two treatments. Both patient subgroups with non‐allergic, non‐eosinophilic rhinitis and perennial allergic rhinitis benefitted from therapy. Basal and stimulated plasma Cortisol levels remained unchanged with either dose of budesonide, and no increase in adverse efTects occurred with higher dose therapy.
