The present invention concerns colloidal vectors with polyaminoacid structure for oral release of peptides and proteins and a method for their production. Specifically, the invention concerns systems for the release of active substances, specifically peptides and proteins, by means of their incorporation in nanoparticles, nano-aggregates or complexes based on properly derivatized synthetic polyaminoacids. These polymeric systems are proposed to release peptide drugs or proteins from oral dosage forms in an effective manner, besides increasing the physicochemical stability of proteins in liquid or solid pharmaceutical dosage forms.
