title: A trial of ICI 74,917 in seasonal allergic rhinitis.
abstract: Twenty-four patients with seasonal allergic rhinitis were treated in a randomized double-blind trial of 6 weeks' duration, using either ICI 74,917 (0.5 mg in each nostril four times a day) or an identical placebo aerosol. Four patients receiving placebo were withdrawn from the trial because of the deteriorationin their rhinitis. The twelve patients using ICI 74,917 were protected as assessed by a combined total symptom score, which was statistically significant (P less than 0.05), from weeks 1 to 4 when the pollen counts were highest.
