Inclusion of Vitamin D2 in β-Cyclodextrin. Evaluation of Different Complexation Methods

Abstract
Evaluation of inclusion complexation of vitamin D2 with β-cyclodextrin in aqueous solution and solid state was performed by Phase Solubility Diagramm, HPLC, DSC, X-RAY Diffractometry, NMR. Solid inclusion complexes were prepared by spray-drying, kneading and solid dispersion. The dissolution profiles of the complex either in powder or in tablets were studied in order to select the best inclusion process
