Abstract:
This was a double-blind, randomized, placebo-controlled, multicenter, parallel study comparing the effectiveness, at recommended doses, of an extended-release formulation of brompheniramine maleate and terfenadine in the treatment of allergic rhinitis. Subjects with symptoms of seasonal and/or perennial allergic rhinitis received brompheniramine 12 mg (n = 106), 8 mg (n = 105), terfenadine 60 mg (n = 106), or placebo (n = 53) twice daily for 14 days. On treatment days 3, 7, and 14, symptom severity ratings (i.e., rhinorrhea, sneezing, nasal congestion, itchy nose, eyes or throat, excessive tearing, postnasal drip) were completed by the physician; subjects and physicians each completed a global efficacy evaluation. Brompheniramine 12 mg and 8 mg and terfenadine were more effective than placebo (p ≤ 0.05) on the physicians’ global; brompheniramine 12 mg was more effective than terfenadine (p ≤ 0.05) on days 7 and 14 and brompheniramine 8 mg on day 3. On the subjects’ global evaluation, brompheniramine 12 mg and 8 mg and terfenadine were more effective than placebo (p ≤ 0.05); brompheniramine 12 mg was more effective than terfenadine (p ≤ 0.05) on days 7 and 14 and brompheniramine 8 mg on day 3. In general, brompheniramine 8 mg was comparable to terfenadine. On days 3 and 7, the total symptom and total nasal symptom severity scores for subjects receiving brompheniramine 12 mg were significantly more improved than for placebo (p 〈 0.05); terfenadine was not different from placebo; brompheniramine 12 mg was significantly better than terfenadine on day 7 (p 〈 0.05) for reducing total symptom severity and on days 3, 7, and 14 for reducing total nasal symptom severity. Adverse experiences were reported by 155 (41.9%) of the 370 subjects enrolled in the study. The overall rate of adverse experiences in the brompheniramine 12 mg treatment group (57.5%) was significantly greater (p 〈 0.05) than for brompheniramine 8 mg (38.1%), terfenadine (31.1%), and placebo (39.6%). In conclusion, an extended-release formulation of brompheniramine 12 mg or 8 mg bid alleviates allergic rhinitis symptoms and brompheniramine 12 mg provides significantly better relief of these symptoms than terfenadine 60 mg bid.
