Abstract: The present invention specifically refers to a pharmaceutical system for preparation of solid pharmaceutical forms for administering therapeutic substances improving their bioavailability; said system is particularly suitable for administering sensitive active principles by their proteinaceous nature or by being nucleic acids since polymeric excipients with good matrix and bioadhesion properties are used which together with the impermeability conferred by the applied coating make the prepared system a delivery form with excellent performance.
