In a different perspective, chitosan-anionic polymers-based extended-release tablets were developed and the feasibility of using this system for the sustained release of highly water-soluble drugs with high drug loading was tested. Here, sodium valproate and valproic acid combined were chosen as the model drugs. Anionic polymers such as... [Pg.283]

The physical or chemical crosslinking of polymers can be also realized in water-in-oil (W/O) emulsion systems. In this case, aqueous droplets of prepolymers are stabilized by oil-soluble surfactants in a continuous oil phase. Hyaluronan-based microgels were prepared by crosslinking of carboxylic units of hyaluronan with adipic dihydrazide in aqueous droplets [19]. Chitosan-based microgels were prepared by crosslinking of chitosan chains with glutaraldehyde in aqueous droplets [20-25],... [Pg.6]
