| abstract |
Pharmaceutical compositions with differentiated, controlled and/or site-specific release are claimed for the oral or rectal administration of peptide or protein substances, including antibodies and soluble receptors capable of antagonising the pathogenetic role of several cell mediators such as interleukines, chemokines, growth factors, tissue necrosis factors, and interferons. Through the incorporation of the peptide or protein substance inside a controlled and/or site-specific release preparation, the application of this invention permits transporting the substances directly into the intestinal environment where a reduced quantity of proteolytic enzymes is present, a less aggressive microenvironment for the integrity of the protein structure and sequence. |
