title: Beclomethasone dipropionate nasal aerosol spray in allergic rhinitis: a comparison of three delivery systems.
abstract: In this 3-way crossover study, the currently marketed beclomethasone dipropionate aerosol canister was sprayed intranasally through three different delivery adapters by 48 adult patients with allergic rhinitis. The adapters were evaluated and compared for force of spray, ease of use, preferred length of nozzle, and effectiveness. While all three were considered effective for symptom relief, there was a clear preference for both of the new longer, snout-like nozzle adapters over the currently available delivery system.
