PMPRC Researcher wins Graduate Student Award at RDD Europe 2017

Cordula Weiss, a postgraduate researcher with the PMBRC, has won the VCU RDD Peter R. Byron Graduate Student Award at the Respiratory Drug Delivery (RDD) Europe 2017 International Symposium, held in Nice, France from 25th - 28th April. The award is presented for excellence in research, and understanding and defence of Cordula's work at RDD Europe 2017. Further information about RDD can be found on the RDD Online Site

Cordula presented a poster at the conference, and summarised her research as follows:

"At the PMBRC, I’m working on a research project in the field of respiratory drug delivery, more specifically in drug delivery based on dry powder inhalation. A typical formulation used in dry powder inhalers consists of the drug, very fine particles in the size range of 1 to 5 um, and larger carrier particles, usually lactose. These particles all stick together during storage but are separated when being inhaled. The forces that hold them together depend on a number of factors and my research project is about understanding how we can fine-tune a number of these factors by using particular processing and manufacturing parameters. These are known to influence the material characteristics of inhalable drug particles which in turn affect the forces between the components of the final product – the “stickiness” so to speak. I use beclomethasone dipropionate (BDP), an anti-inflammatory agent, as a model drug and prepare crystalline particles (solvates) from supersaturated solution using different solvents.

The work I presented at RDD Europe 2017 describes the novel use of a combination of X-ray diffraction (XRD), nuclear magnetic resonance (NMR) spectroscopy, scanning electron microscopy (SEM) and atomic force microscopy (AFM) to look at the properties of these solvates, at the interaction between BDP and the solvent and at the impact these interactions may have on their physical characteristics."
