PHARMACEUTICAL COMPOSITION, METHOD FOR PREPARING THE SAME, METHODS FOR INHIBITING THE RATE AGENT PRECIPITATION RATE, AND FOR REDUCING INTERPATIENT VARIABILITY WITH REGARD TO BIODISPONIBILITY AND / OR CONCENTRATION, AND / OR CONCENTRATION WATER SOLUBLE Aether CELLULOSE OR AN ESTER OF A WATER SOLUBLE ETHER CELLULOSE

摘要

"pharmaceutical composition, method for preparing same, methods for inhibiting the precipitation agent of the solution agent in the GI tract, and for reducing inter-patient variability with respect to bioavailability and / or plasma concentrations of the agent, and use of 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 soluble ether cellulose in water or an ester of a water-soluble ether cellulose. Water soluble ether cellulose or ester of a water soluble ether cellulose present in the composition inhibits the precipitation rate of the solution agent.
