title: Ipratropium bromide aqueous nasal spray for patients with perennial allergic rhinitis: a study of its effect on their symptoms, quality of life, and nasal cytology.
abstract: Ipratropium bromide is an anticholinergic agent with topical activity that has been studied as a freon-propelled aerosol spray for therapy of nonallergic rhinitis. This is the first report of its use both as an aqueous nasal spray and in perennial allergic rhinitis. In this study 123 patients who had symptoms of perennial allergic rhinitis were randomized to receive ipratropium bromide 21 micrograms or 42 micrograms or placebo, one spray per nostril three times a day for 4 weeks. Patients maintained daily diaries of duration and severity of nasal symptoms and were evaluated weekly. Mean duration and severity of rhinorrhea was decreased in both ipratropium bromide treatment groups by comparison with placebo, with consistently greatest improvement in the group treated with ipratropium bromide 42 micrograms per nostril three times a day. No statistically significant differences occurred among treatment groups in duration or severity of postnasal drip, congestion, or sneezing. Seventy percent of patients treated with 42 micrograms of ipratropium bromide thought it had good or excellent effect on rhinorrhea (p less than 0.05 vs placebo); significantly more patients thought that it had improved the quality of life (p = 0.02). No changes occurred in nasal cytology, and no significant local or systemic adverse events occurred. These data indicate that ipratropium bromide significantly decreases the rhinorrhea of perennial allergic rhinitis.
