Abstract
Aerosol therapy enables one to administer a drug at high concentrations to the region requiring medication and consequently to reduce general side-effects. The nasal cavity being the entrance to the airway allows easier administration of drugs compared with other regions and therefore is suitable for aerosol therapies. The current approach was to give an initial treatment using a topical nasal steroid in combination, one of the aerosol therapies for the patients with Japanese cedar pollinosis, and we were able to delay the development of clinical symptoms, thus demonstrating the clinical effect of the aerosol therapy. Mainly based on this finding, we describe the effectiveness of aerosol therapies for allergic rhinitis.
