Abstract
The present invention discloses a patch for use in administration of an ionic medicine into a living body by infiltration of the ionic medicine into the living body through the living body surface without voltage application, characterized in that the patch comprises an ion-exchange membrane having a surface roughness (Rz) of 7 μm or less at its part to be brought into contact with the living body surface and an ionic medicine impregnated into the ion-exchange membrane.
Claims10
A patch for use in administration of an ionic medicine into a living body by infiltration of the ionic medicine into the living body through the living body surface without voltage application, wherein the patch is free of electrodes and comprises an ion-exchange membrane having a surface roughness (Rz) of 1 μm or less at its part to be brought into contact with the living body surface and an ionic medicine impregnated into the ion-exchange membrane.
A patch for use in administration of an ionic medicine into a living body, wherein the patch is free of electrodes, the patch consisting of an ion-exchange membrane having a surface roughness (Rz) of 1 μm or less at its part to be brought into contact with the living body surface, an ionic medicine-containing layer formed on the side of the ion-exchange membrane opposite to its side having the part to be brought into contact with the living body surface, an ionic medicine impregnated into the ion-exchange membrane and an ionic medicine-containing layer, a solvent-substantially-impermeable sheathing material and an adhesive layer for attachment of the patch material to the living body surface.
A method for administering an ionic medicine into a living body, comprising the steps of:
- preparing a patch comprising an ion-exchange membrane having a surface roughness (Rz) of 1 μm or less at its part to be brought into contact with a living body surface and an ionic medicine impregnated into the ion-exchange membrane, wherein the patch is free of electrodes,
- contacting the patch to the living body surface, and
- allowing the medicine to infiltrate into the living body transdermally, without application of a voltage.
