Theses and Dissertations

The overall aim of this research project was to evaluate effects of spray drying parameters and storage conditions on solid-state characteristics and aerosol performance of excipient enhanced growth (EEG) powders and to formulate a stable and highly dispersible tobramycin EEG powder to be delivered to pediatric cystic fibrosis subjects using a novel positive pressure dry powder inhaler.

Micrometer-sized albuterol sulfate EEG powders were produced using a medium-sized nebulizer and optimized spray drying conditions. Using trileucine as the dispersion enhancer improved the aerosol performance but showed increased moisture absorption compared to the L-leucine formulation.

The optimized spray drying conditions were then …
