High-Resolution Characterization of Structure, Interaction, and Miscibility of Drug Products

The local interactions between a drug and its surrounding environment is critical in both small and large molecule formulations. For small molecules, the drug-polymer interaction is needed to ensure that the drug does not crystallize in an amorphous solid dispersion. For proteins, phase separation in lyophilized formulations will lead to reduced stability and the potential for aggregation.

In this presentation, the ability to probe these local structures and interactions in both small and large molecule systems will be shown. g. degrees of interaction, changes in conformation) can impact functional properties such as crystallization and aggregation.
