This paper presented the swelling properties of propranolol HCl-loaded polyvinyl alcohol-graft-lactic acid (PPH-loaded PVA-g-LA) hydrogel films. The swelling properties including swelling-deswelling measurement and swelling behaviour in different environmental stimuli fluids such as water, various pH, and various ionic strength were determined. It was found that the swelling properties of the PPH-loaded PVA-g-LA hydrogel films depend on the LA amount addition. They had a good swelling and deswelling in water and acetone. The PPH-loaded PVA-g-LA hydrogel films showed the high swelling in the medium pH 7. Thus, the prepared PPH-loaded PVA-g-LA hydrogel films had a good swelling property that could be used to controlled drug release in pharmaceutical product.
