    摘要: The present invention provides a polymer-combined drug having directional characteristics to digestive organs, wherein it comprises a medicine combined with a polymer which has an alkyleneoxy group as a repeating unit. The polymer-combined drug is produced by reacting a polyoxyalkylene glycol having one or more terminal functional groups and a medicine, if necessary in a solvent, and if necessary in the presence of a catalyst. It is able to administer the drug orally or by intravenous injection so as to maintain the concentration in blood stably for a long time, and to absorb or take in digestive organs such as the stomach and intestines directly.
