Strategies to address low drug solubility in discovery and development

HD Williams, NL Trevaskis, SA Charman… - Pharmacological …, 2013 - Elsevier
Drugs with low water solubility are predisposed to low and variable oral bioavailability and,
therefore, to variability in clinical response. Despite significant efforts to “design in” …

Evaluation of amorphous solid dispersion properties using thermal analysis techniques

JA Baird, LS Taylor - Advanced drug delivery reviews, 2012 - Elsevier

Solid state amorphization of pharmaceuticals

JF Willart, M Descamps - Molecular Pharmaceutics, 2008 - ACS Publications
Amorphous solids are conventionally formed by supercooling liquids or by concentrating
noncrystallizing solutes (spray-drying and freeze-drying). However, a lot of pharmaceutical …

Thermodynamic aspects of vitrification

B Wowk - Cryobiology, 2010 - Elsevier
Vitrification is a process in which a liquid begins to behave as a solid during cooling without
