Sulindac imprinted mungbean starch/PVA biomaterial films as a transdermal drug delivery patch

In this work, biodegradable biomaterial films for sulindac (SLD) recognition are synthesized from mungbean starch (MBS), PVA, and plasticizers by using UV irradiation process and casting methods. The optimal UV irradiation time for the preparation of SLD imprinted biomaterials films was about 30 min. Mechanical properties, recognition ability, and SLD release property for prepared films were investigated. From the results of recognition ability, we verified that these SLD imprinted biomaterial films have the binding site for SLD. The release properties of SLD was examined with the change of pH and temperature. The results indicate that the SLD release in pH 10.0 was higher than in pH 4.0. SLD release was also evaluated using an artificial skin. Results of the artificial skin test verified that SLD was released constantly for 20 days.
