摘要:
A medical adhesive sheet comprising a support and an adhesive layer formed on one side of said support, wherein the adhesive layer comprises an adhesive polymer having a weight average molecular weight of not less than 2,000,000, preferably not less than 2,500,000, and at least one plasticizer compatible with said polymer. The medical adhesive sheet of the present invention simultaneously satisfies the adhesive property to the skin and low irritation property, since it can retain the plasticizer in the adhesive layer, even without a crosslinking treatment. The effects of the present invention can be exerted irrespective of the kind of functional group that the plasticizer and drug have.

The present invention aims at provision of a patch with suppressed occurrence of adhesive residue on the skin after peeling in the presence of water due to perspiration and the like. The patch has an adhesive layer provided on at least one surface of a support, and the adhesive layer is formed by blending the following component (A) - component (C): (A) a copolymer obtained by copolymerization of a monomer containing a carboxyl group, (meth)acrylic acid ester and vinylpyrrolidone as essential components; (B) a copolymer obtained by copolymerization of a monomer having a basic group and (meth)acrylic acid ester as essential components; and (C) a liquid component, and crosslinking the blend.

The present invention provides a percutaneous absorption preparation which hardly causes the coloration phenomenon and is excellent in the stability of the drug content. The percutaneous absorption preparation comprises a support and a pressure-sensitive adhesive layer formed on at least one side of the support, wherein the pressure-sensitive adhesive layer contains a percutaneous absorptive drug and at least one of 2-mercaptobenzimidazole and propyl gallate, with the proviso that the percutaneous absorptive drug is not 6-amino-5-chloro-1-isopropyl-2-(4-methyl-1-piperazinyl)benzimidazole and pharmacologically acceptable salt thereof.
摘要:
The present invention aims at providing an adhesive preparation wherein a drug is sufficiently dissolved in an adhesive layer and is not easily separated from the adhesive layer even during preservation of the adhesive preparation. The present invention provides an adhesive preparation having an adhesive layer on at least one surface of a support, wherein the adhesive layer comprises a first synthetic rubber having a viscosity average molecular weight of 1,600,000 - 6,500,000, a drug, an organic liquid component and a tackifier. The present invention further provides the aforementioned adhesive preparation, wherein the organic liquid component is contained in the adhesive layer in a proportion of 20 wt% or above relative to the total weight of the adhesive layer.
