Preparation, Characterization and Drug Release Properties of Polyvinyl Alcohol and Polyvinyl Pyrolidone Blended Hydrogels

In this work, a new polyvinyl alcohol (PVA)/polyvinyl pyrrolidone (PVP) /Pumice composite has been synthesized by using gamma rays irradiation technique. The chemical characteristics of the hydrogels were determined by Fourier Transform Infrared Spectroscopy method. The properties of the hydrogels were investigated in terms of swelling, drug uptake and release behaviors. 5-Fluorouracil (5-FU) was used as a model drug for the study of drug uptake and release behaviour of hydrogels. The addition of pumice in the gel structure improved drug uptake and release capability of the new hydrogels
