A laminate patchable to a living body and that includes a pressure-sensitive adhesive layer for patching to the living body and a substrate layer disposed on a one-side surface in a thickness direction of the pressure-sensitive adhesive layer and supporting the pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer contains a first carboxylic acid ester and the substrate layer contains a second carboxylic acid ester.

Laminate patchable to living body

An adhesive preparation containing bisoprolol includes a backing and a pressure-sensitive adhesive layer formed on one side of the backing. The pressure-sensitive adhesive layer contains a polymer prepared through copolymerization of monomer components including a hydroxyl group-containing monomer and an alkyl (meth)acrylate monomer (component (A)), a polymer prepared through copolymerization of monomer components including a methyl methacrylate monomer and a butyl methacrylate monomer (component (B)), and bisoprolol (component (C)).

Adhesive preparation containing bisoprolol

The patch according to an embodiment of the present invention includes: a support; and a pressure-sensitive adhesive layer on at least one surface of the support, wherein: the pressure-sensitive adhesive layer contains an acrylic copolymer obtained by copolymerizing monomer components containing (a) at least one kind of a monomer of a (meth)acrylic acid alkyl ester and (b) at least one kind of a monomer of an N-hydroxyalkyl(meth)acrylamide; a content of the (meth)acrylic acid alkyl ester monomer (a) with respect to a total amount of the monomer components is 50 wt % to 90 wt % and a content of the N-hydroxyalkyl(meth)acrylamide monomer (b) with respect to the total amount is 1 wt % to 20 wt %; and the monomer components are substantially free of a monomer having a carboxyl group.
