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.

Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
Antiasthma Drugs: β2-Adrenoceptor Agonists
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce relaxation in these...

Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
Transdermal patches transport drugs through the...
