Investigating the Variations in Molecular Mobility within Amorphous Formulations using Terahertz Spectroscopy
… polymer, residual water, and other additives. Polyvinylpyrrolidone/vinyl acetate copolymer (PVPVA), used to formulate poorly water-soluble drugs, was used as the polymer for all investigations. PVPVA exhibits hygroscopic behaviour and will absorb water over time. The residual water inherently …

Insight into Nucleation Kinetics of Flufenamic Acid Cocrystal Formulation in Solution: Investigating the Role of Polymeric Excipients through Combined Experimental and Computational Approaches
… excipients. The impact of selected polymers, polyvinyl pyrrolidone (PVP), polyvinylpyrrolidone-vinyl acetate copolymer (PVP-VA), polyethylene glycol (PEG), and soluplus (SOL), on the nucleation and growth of cocrystals of FFA with theophylline (FFA-TP) and nicotinamide (FFA-NIC) was evaluated. …
