Abstract:
PROBLEM TO BE SOLVED: To provide a patch achieving a patch preparation having remarkably excellent cohesive power, showing no stringing when peeled off from the skin, and having excellent stability.SOLUTION: The patch includes a support and an adhesive layer arranged on at least one-side surface of the support. The adhesive layer includes an acryl-based copolymer formed by copolymerizing a monomer mixture containing (a) a (meth)acrylic alkyl ester, (b) a diketone group-containing monomer, and the acryl-based copolymer is cross-linked by a diamine-based compound.
Abstract:
PROBLEM TO BE SOLVED: To provide a patch facilitating the stripping of a strippable liner from a patch body without contact of a finger with an adhesive face, hardly causing rounding of the patch body at patching or adhesion of the adhesive face to each other, and facilitating the patching of the patch body to the skin surface without the contact of the finger with the adhesive face at the patching. SOLUTION: The patch includes the patch body 4 having a supporter 3, the adhesive layer 2 laminated at least on one surface of the supporter 3, and the strippable liner 1 laminated on the surface of the adhesive layer 2 of the patch body 4 at the opposite side of the supporter 3 side. The patch is regulated so that the plane area of the patch body 4 may be 1.5-15 cm 2 , the ratio {[the plane area (cm 2 ) of the strippable liner 1]/[the plane area (cm 2 ) of the patch body 4]} of the plane area of the strippable liner 1 to the plane area of the patch body 4 may be 1.1-7, and the strippable liner 1 may have a parting line 11.

Abstract:
PROBLEM TO BE SOLVED: To provide a selegiline-containing adhesive preparation which stably administers selegiline for a long term with a low adverse reaction. SOLUTION: The selegiline-containing adhesive preparation is obtained by forming a pressure-sensitive adhesive layer containing (-)-(R)-N,α-dimethyl-N-2-propynylphenethylamine and/or a pharmaceutically acceptable salt thereof, a pressure-sensitive adhesive, and a component being liquid at 25°C and having two or more ester bonds in one molecule, on at least one side of a support medium.

Abstract:
PROBLEM TO BE SOLVED: To provide a patch suppressing adhesive transfer onto the skin when peeled off and suppressing its own peeling off in the presence of moisture due to perspiration or the like. SOLUTION: The patch is such that at least one side of a substrate bears a self-adhesive layer which is obtained by crosslinking a compounded product comprising (A) a copolymer obtained by copolymerization of a carboxy-containing monomer, a (meth)acrylic ester and vinyl pyrrolidone as the essential components, (B) a copolymer obtained by copolymerization of a basic group-containing monomer as the essential component, (C) a liquid component and (D) an acidic compound.

Abstract:
PROBLEM TO BE SOLVED: To provide a packaging structure and a packaging method for packaging a plaster containing a liquid ester compound in an adhesive layer, using a packaging material, configured to reduce the amount of moisture in a packaging structure body to reduce the amount of moisture in the packaged plaster, thereby preventing adhesion of the plaster from being changed.SOLUTION: In a plaster packaging structure, a plaster containing a liquid ester compound in an adhesive layer is air-tightly packaged in a packaging material. An innermost layer of the packaging material in the packaging structure is formed of a layer composed of ethylene-vinyl alcohol copolymer. A moisture shielding layer is formed outside thereof. Specifically, moisture content in the layer formed of the ethylene-vinyl alcohol copolymer is preferably 2.0 wt.% or lower.
Abstract:
PROBLEM TO BE SOLVED: To provide a selegiline-containing adhesive preparation which has high selegiline stability and a restrained generation amount of impurities. SOLUTION: The selegiline-containing adhesive preparation is obtained by forming an adhesive layer containing (-)-(R)-N,α-dimethyl-N-2-propynylphenethylamine and/or a pharmaceutically acceptable salt thereof, a pressure-sensitive adhesive, and one or more stabilizers selected from the group consisting of 2-mercaptobenzimidazole, sodium sulfite, butylhydroxyanisole and butylhydroxytoluene, on at least one side of a support medium.
