Abstract
The invention relates to acrylic hydrogels with pendant cyclodextrins, the preparation and application thereof as release systems and components of contact lenses. The method for obtaining acrylic hydrogels with pendant cyclodextrins is characterized in that the hydrogels are formed by a polymer lattice obtained by polymerization of mono- and bifunctional acrylic or methacrylic monomers and monomers having glycidyl groups in their structure, to which cyclodextrin units are covalently bound once formed; and the use and applications of the compositions in the preparation of contact lenses with the capacity for incorporating drugs, active substances or demulcents useful in the treatment of pathological or physiological conditions, in the production of topical, transdermal or transmucosal release systems for medicinal products or active substances, and in the preparation of cosmetics.
