Abstract:
Our research focuses on developing fundamental understanding of particle properties and their interactions at the nano and micro scales, along with translating that knowhow to innovate powder based solid form products [1-39]. Recent work has specifically targeted pharmaceutical industry with a hope to satisfy unmet industry and patient needs. Unique contributions that will be discussed in this presentation include predictive property enhancements for fine powders, their blends, and compressed tablets through particle engineering, potentially enabling digital product design and manufacturing of high-quality, low-cost, smaller tablet products, as well as process understanding via multi-scale modeling. We have leveraged these recent fundamental advances to develop innovative processes and products spanning important areas such as; overcoming the difficulties in processing pharmaceutical powders due to their high cohesion via solventless mechanical coating of nanoparticles on their surfaces; use of modeling tools for enhanced process and product understanding; and improved bioavailability of poorly water-soluble drugs. Highlights of the first one of these topics will be presented including recent advances uncovering the role of fine particle agglomeration on powder behavior and power-law relationship between agglomeration, flowability, and packing where the granular Bond number could be used as a dimensionless scaling parameter. The synergistic enhancements in the blend or formulation properties will be highlighted including blend uniformity, flowability, compaction properties, and enhanced capability for direct blend direct compaction (DB-DC) tableting at either high or very low drug loadings.
