• A flunisolide-containing intranasal spray and matching placebo were used in an eight-week, double-blind parallel study in 67 patients with perennial rhinitis. Seventeen patients who did not benefit from treatment with the placebo then switched to flunisolide for a six-week open trial. Flunisolide-treated patients showed greater improvement in both duration and severity of symptoms, as well as a greater preference for flunisolide; 75% of patients either had "mild" symptoms or were asymptomatic and 67% stated that they experienced "substantial" or "total" control of symptoms. No serious side effects were encountered. Chief side effects in both drug and placebo groups were brief, mild, nasal burning and stinging on spray application. The drug exhibited no adverse effects on adrenal function (morning plasma cortisol levels).
