Core-shell microparticles based on acrylic ion exchange resin/polysaccharides as drug carriers

Core-shell microparticles consisted of acrylic ion exchange resin as the core and two natural polymers (gellan or xanthan) as the shell are presented in this paper. These new polymeric materials were characterized by FT IR spectroscopy, optical microscopy and swelling degree in water. Taking into account the possibility of their use in the medical and pharmaceutical fields, the retention and release capacities of cefotaxime sodium salt were investigated.
