Efficacy and safety of once-daily treatment with beclomethasone dipropionate nasal aerosol in subjects with seasonal allergic rhinitis
An aerosol formulation may be preferred by some allergic rhinitis (AR) patients, to avoid the “wet feeling” and nasal runoff associated with aqueous nasal corticosteroid sprays. Beclomethasone dipropionate (BDP) hydrofluoroalkane nasal aerosol is a recently developed, nonaqueous, nonchlorofluorocarbon formulation of BDP for the treatment of AR. This study was designed to evaluate the efficacy, safety, and quality-of-life benefits of BDP nasal aerosol in subjects with seasonal AR (SAR). Eligible subjects (≥12 years of age) enrolled in this 2-week study were randomized to either BDP nasal aerosol at 320 μg/day (n = 169) or placebo (n = 171). Efficacy assessments included reflective and instantaneous total nasal symptom scores (rTNSS and iTNSS, respectively), Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) score, reflective and instantaneous total ocular symptom scores (rTOSS and iTOSS, respectively), and physician-assessed total nasal symptom score (PNSS). Safety and tolerability were also assessed. Subjects receiving BDP nasal aerosol showed a significantly greater improvement from baseline in average A.M. and P.M. rTNSS versus placebo (treatment difference, −0.91; 95% confidence interval, −1.3, −0.5; p < 0.001) over 2 weeks of treatment. Greater improvements in rTNSS with BDP nasal aerosol compared with placebo were evident by day 2 and were maintained throughout the treatment period. Similarly, significant improvements were seen with BDP nasal aerosol in iTNSS (p < 0.001) and RQLQ score (p = 0.005) compared with placebo. Treatment with BDP nasal aerosol also resulted in greater improvements in rTOSS (p = 0.002), iTOSS (p = 0.003), and PNSS (p < 0.001) relative to placebo. BDP nasal aerosol was well tolerated and the overall safety profile was similar to placebo. Results from this clinical study indicated that BDP nasal aerosol provided significant AR symptom relief and was well tolerated in patients with SAR with an overall safety profile similar to placebo.

More about this publication?
- Allergy and Asthma Proceedings is a peer reviewed publication dedicated to distributing timely scientific research regarding advancements in the knowledge and practice of allergy, asthma and immunology. Its primary readership consists of allergists and pulmonologists.
The goal of the Proceedings is to publish articles with a predominantly clinical focus which directly impact quality of care for patients with allergic disease and asthma and by having the potential to directly impact the quality of patient care. AAP welcomes the submission of original works including peer-reviewed original research and clinical trial results. Additionally, as the official journal of the Eastern Allergy Conference (EAC), AAP will publish content from EAC poster sessions as well as review articles derived from EAC lectures.
Featured topics include asthma, rhinitis, sinusitis, food allergies, allergic skin diseases, diagnostic techniques, allergens, and treatment modalities. Published material includes peer-reviewed original research, clinical trials and review articles.
Articles marked "F" offer free full text for personal noncommercial use only.
The journal is indexed in Thomson Reuters Web of Science and Science Citation Index Expanded, plus the National Library of Medicine's PubMed service.
