Nanospheres comprising a biocompatible polysaccharide

摘要: Microspheres, having a size lower than 1 ν and comprising biocompatible polysaccharidic polymer, are prepared with process the precipitation of polymer induced by means supercritical antisolvent (SAS). These microspheres used as vehicling agents or carriers in preparation pharmaceutical compositions administrable oral, nasal, pulmonary, vaginal rectal route. can also be advantageously agent for treatment human diseases associated genic defects, diagnostics agro-alimentary industry.
