Upon ingestion outer film coat dissolves exposing the coated tablet to the gastric fluids. Once the water soluble polymer from coat gets dissolved, pores are formed which allow penetration of fluid inside the membrane leading to hydration of core-forming hydrogel. Drug release occurs via slow diffusion out of the gel layer and subsequent gel erosion. structure
