Incorporation of water molecules in the crystal structure of an organic compound has strong effects on its physical and chemical properties. Therefore, the study on stability of water-incorporated pharmaceutical compounds and mechanisms of
hydration and
dehydration is very important for the pharmaceutical industries. The main goals of the present research project were quantitative description of the
crystallization and solid-state transformations of pseudopolymorphs of sodium naproxen in order to provide fundamental information concerning stability of the pseudopolymorphic forms. Furthermore, macroscopic phenomena of size reduction and anisotropic water-removal by dehydration were
