    Solubility of Cyclodextrins and Drug/Cyclodextrin Complexes

    Cyclodextrins (CDs), a group of oligosaccharides formed by glucose units bound together in a ring, show a promising ability to form complexes with drug molecules and improve their physicochemical properties without molecular modifications. The stoichiometry of drug/CD complexes is most frequently 1:1. However, natural CDs have a tendency to self-assemble and form aggregates in aqueous media.

    α-Cyclodextrin is a hexasaccharide derived from glucose.It is related to the β- (beta) and γ- (gamma)cyclodextrins, which contain seven and eight glucose units, respectively.All cyclodextrins are white, water-soluble solids with minimal toxicity. Cyclodextrins tend to bind other molecules in their quasi-cylindrical interiors.
