Interactions between b-cyclodextrin or hydroxypropyl b-cyclodextrin, as well as the possibility of obtaining inclusion complexes, were evaluated by several methods: a phase solubility diagram, high-power liquid chromatography, differential scanning calorimetry and X-ray diffractometry. Solid inclusion complexes were prepared by spray-drying, kneading and solid dispersion. The dissolution profiles of the obtained powders were studied in order to define the most appropriate cyclodextrin, preparation method and molar ratio to use in the production of a fenofibrate inclusion complex. Finally, tablets were prepared with the powder of the complex and characterized by dissolution studies.

Abstract
Interactions between b-cyclodextrin or hydroxypropyl b-cyclodextrin, as well as the possibility of obtaining inclusion complexes, were evaluated by several methods: a phase solubility diagram, high-power liquid chromatography, differential scanning calorimetry and X-ray diffractometry. Solid inclusion complexes were prepared by spray-drying, kneading and solid dispersion. The dissolution profiles of the obtained powders were studied in order to define the most appropriate cyclodextrin, preparation method and molar ratio to use in the production of a fenofibrate inclusion complex. Finally, tablets were prepared with the powder of the complex and characterized by dissolution studies.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
