Abstract |
We undertook this trial to determine whether ipratropium bromide nasal spray 0.03% (IB) reduced the nasal hypersecretion associated with nonallergic perennial rhinitis (NAPR) without causing excessive dryness or irritation of the nasal mucosa. We compared two drug doses of IB (21 micrograms and 42 micrograms per nostril) to a placebo, administered as two sprays to each nostril twice daily. The study design consisted of a 1-week screening period without treatment, a 1-week single-blind placebo period, a 4-week double-blind treatment comparison period, and a 1-week follow-up period without medication to evaluate nasal rebound. One hundred fifty-two patients were entered and 140 completed the trial. Both doses of IB reduced the severity and duration of rhinorrhea compared with placebo (P = .05 and .03, respectively). Treatment differences were noticeable during the first week of therapy, continued to widen during the second week, and then remained stable throughout the next 2 weeks. There was no evidence of nasal rebound observed during the week after treatment. The drug was well tolerated with side effects limited to infrequent nasal adverse events of nasal dryness, blood-tinged mucus, and epistaxis occurring in 2% to 6% of patients. We conclude that IB is a safe and effective therapy for control of rhinorrhea associated with NAPR.
