✦ Synopsis


The effect of adding b-Cyclodextrin with poly(vinyl alcohol) (PVA) hydrogel on the release of a water-soluble component has been investigated. It is found that the release of a model drug, salicyclic acid, from PVA matrix in the presence of b-cyclodextrin prolonged considerably the release of the profile of the drug from the PVA gel. The profound influence of b-cyclodextrin on the drug release has been assigned to the ability of b-cyclodextrin to form an inclusion complex with salicyclic acid.
