Hydrophobically Modified Amphiphilic Cylodextrins as Novel Carriers for Controlled Delivery of Water-Soluble Drugs

Abstract:

Article Preview

Hydrophobically modified derivative of a γ-cyclodextrin, functionalized with perfluoro alkyl ester group, was prepared and investigated for its potential use as a sustained release carrier for water-soluble drug molsidomine, a peripheral nitrovasodilator used in the treatment of angina pectoris. The molecular encapsulation of molsidomine by the amphiphilic cyclodextrin, octakis(6-O-perfluorobutanoyl)-γ-cyclodextrin (γ-CyD-F), was confirmed by DSC and XRD studies. The in-vitro release of molsidomine from peanut oil suspensions into aqueous phase was found to be significantly retarded by the complexation with γ-CyD-F, mainly due to the hydrophobic properties of the γ-CyD-F.
