Abstract (en)
[origin: WO2005123034A2] The present invention relates to microparticulate systems consisting of a gastroresistant, biocompatible and biodegradable polymer matrix, comprising a gastroresistant and enterosoluble polymer, a cryoprotector or lyoprotector, a divalent or trivalent metal salt of i biocompatible and biodegradable polymer having acid groups, and biologically active substances. Such gastroresistant microparticulate systems are used for the administration, preferably oral, of biologically active substances to animal species. The special composition of such microparticulate systems allows the protection of said biologically active substances from degradation by proteases and gastric acid, allowing their release into the intestine, where they may perform their activities.
