Oral Galenic Form, Polymer Production Method and Use of Same

The polymers according to the invention comprise a polysaccharide block (17) and several hydrophobic polyacrylic blocks (18) enabling the polymer to remain intact until it reaches the colon. The polysaccharide block is degraded by the colonic microflora irrespective of the pH, while the polyacrylic blocks are solubilized at neutral pH. Colon-specific release of the active ingredients is thus provided in all cases. These polymers may serve as a coating in particular for tablets, gel capsules, granules or microgranules, or serve as matrix agents in the preparation of such pharmaceutical forms. This invention concerns the fields of medicine, pharmacy and dietetics.
