Characteristics and deposition of aerosol drugs delivered to the nose

Tomasz Robert Sosnowski , Piotr Rapiejko


In vitro measurements of intranasal deposition of aerosol droplets released from three different drug products are presented. The experiments were done in anatomical cast reproduced from CT scans of an adult human. Aerosols released from nasal atomizers were also characterized regarding droplet size distribution, jet geometry and velocity. The results indicate that all tested medicinal aerosols are characterized by similar droplet size but properties of the jets are different, and this is the main factor which influences the spatial distribution of drug deposition in the nasal cavity. In general, nasal aerosols are deposited proximally in the nasal cavity due to high momentum of the jet and constrictions present in internal geometry of the nose.
