Long-term treatment of perennial allergic rhinitis with ipratropium bromide nasal spray 0.06%

Abstract

The purpose of this study was to assess the safety and efficacy of ipratropium bromide nasal spray 0.06% (aqueous solution), 84 μg per nostril three times a day, in reducing nasal hypersecretion in the long-term treatment of patients with perennial allergic rhinitis (PAR). This was an open-label 1-year trial. In the first 6 months all patients were treated with two puffs ipratropium bromide nasal spray 0.06%, 84 μg per nostril three times per day, unless they were unable to tolerate the dose. In the last 6 months the dose could be reduced to the lowest amount required to control rhinorrhea. Ninety-six patients entered the trial, and 47 completed it. Sixty-three patients completed more than 6 months of treatment. Patient and physician global evaluation suggested that ipratropium bromide nasal spray 0.06% is effective in controlling rhinorrhea associated with PAR and can contribute to control of congestion, postnasal drip, and sneezing. There was also a trend toward reduction of mucosal edema and improvement in quality of life. The most common drug-related adverse events were nasal dryness, epistaxis/nose bleed, and increased rhinitis. Most adverse events were mild and resulted in drug discontinuation in less than 10% of patients. Ipratropium bromide nasal spray was well tolerated and not associated with serious drug-related adverse events or clinically significant anticholinergic side effects. Use of ipratropium bromide nasal spray alone or with other standard medications should be considered in treating patients with PAR. (J A LLERGY C LIN I MMUNOL 1995;95:1128-32.)
