Evaluation Of The Regional Drug Deposition Of Nasal Delivery Devices Using In Vitro Realistic Nasal Models, Mandana Azimi

Theses and Dissertations

The overall objectives of this research project were i) to develop and evaluate methods of characterizing nasal spray products using realistic nasal airway models as more clinically relevant in vitro tools and ii) to develop and evaluate a novel high-efficiency antibiotic nanoparticle dry powder formulation and delivery device. Two physically realistic nasal airway models were used to assess the effects of patient-use experimental conditions, nasal airway geometry and formulation / device properties on the delivery efficiency of nasal spray products. There was a large variability in drug delivery to the middle passages ranging from 17 – 57 % and 47 …
