Abstract

PURPOSE: The titled material for contrlling the release of physiologically active substance, consisting of an inner part sealing a physiologically active substance, an inner side film comprising a porous material having a liquid substance capable of dissolving the substance in the pore, and an outer side film comprising a high polymer material through which the substance is freely diffused and penetrated.
CONSTITUTION: The porous film 13 having the through type hole 12 is formed on the periphery of the hollow part 15, the film 14 consisting of a high polymer material, wherein the active substance 2 is freely diffused and penetrated, is made on the surface of the porous film, and a liquid substance is supported in the holes 12 of the porous film, to give the titled material for controlling the release of physiologically active substance. The active substance is dissolved in the liquid substance in the holes upto saturated state, diffused and moved in the film consisting of the high polymer material, and penetrated through it and released. The liquid substance dissolves the active substance in an amount corresponding to that which has been diffused through the film, and by the repetition of this process the substance is released quantitatively and continuously. A resin such as polyurethane, polyvinyl chloride, ethylene copolymer, etc. is used as the high polymer material.
