摘要：
pH responsive chitosan/gelatin hybrid polymer network (HPN) microspheres were prepared via the inverse emulsion crosslinking method. Cimetidine release from the microspheres was studied. The drug only delivers in acidic medium, while the release rate can be controlled by the HPN composition and the degree of deacetylation.
