摘要

"PHARMACEUTICAL COMPOSITION, METHOD FOR PREPARING THE SAME, METHODS FOR INHIBITING THE RA TREATMENT AGENT PRECIPITATION RATE, AND FOR REDUCING INTER-PATIENT VARIABILITY WITH REGARD TO BIODISPONENT AND USE OF AGE / ADDITIONAL AGENCY A water-soluble ether cellulose or an ester of a water-soluble ether cellulose ". A pharmaceutical composition comprising 4- (3'-chloro-4'-fluoroanilino) -7-methoxy-6- (3-morpholine-propoxy) quinazoline or a pharmaceutically acceptable salt thereof (the Agent) and a cellulose ether water soluble or an ester of a water soluble ether cellulose. The water soluble ether cellulose or ester of a water soluble ether cellulose present in the composition inhibits the precipitation rate of the solution agent.
