WATER-SOLUBLE FILM CONTAINING ANTICANCER SUBSTANCE AND PRODUCTION THEREOF

摘要

PURPOSE: A process of preparing a water-soluble film having a high solid content, a low viscosity at wide pH range and excellent dispersion stability without causing solidification is provided. Therefore, the film has excellent dispersion stability and prevents the anticancer substances from being released fast after the destruction of the resin film and is thus effectively used in controlled released drug delivery systems, skin absorbing agents, patch agents or the like. CONSTITUTION: A water-soluble film(1) is prepared by: forming a microcapsule by coating anticancer substances(3) with aminoaldehyde polycondensated resin; and then coating the microcapsule with a water-soluble polymer.
