摘要:
A patch agent of the present invention comprises a support, and an adhesive layer laid on the support and containing an adhesive base and a drug, wherein the adhesive base contains an acrylic polymer substantially having no carboxyl and no hydroxyl in molecules thereof, and a rubber-based polymer, so as to achieve sufficiently high skin permeability of the drug and preparation properties. Accordingly, the present invention enables administration of the drug through skin to be implemented with drug administration effect at a sufficiently high level and on a stable basis.

摘要:
An adhesive which comprises aqueous and nonaqueous polymers suitable for holding an lipophilic drug, etc., and has tackiness and cohesiveness which are sufficient for the plaster of a patch; and a patch employing the adhesive. The adhesive contains a polymer which comprises one or more kinds of acrylic or methacrylic monomer units, at least one kind of the monomer units having a hydroxy group, and which has been crosslinked with a boron compound.
摘要:
A pressure-sensitive adhesive composition for transdermal absorption which contains a drug and a transdermal absorption promoter for the drug, characterized by further containing polyvinylpyrrolidone so as to stabilize the transdermal absorption promoter contained in the adhesive composition. Thus, the transdermal absorption promoter can be prevented from vaporization or degradation and a patch for external use containing the transdermal absorption promoter at a high concentration in using can be provided.

A packaging bag 1 according to the present invention comprises a pair of packaging films 7x, 7y that are disposed facing one another, and are sealed together around a perimeter thereof so as to form a housing portion 9 housing a plaster. On one of the packaging films 7x is provided a protrusion 10 that protrudes toward the other packaging film 7y. When the plaster 2 is packaged, only the protrusion 10 of the packaging film 7x contacts a plaster body 5. The portion contacted by the protrusion 10 is a portion, on the inside of the plaster body 5, that excludes an outer periphery of the plaster body 5. Therefore, even if adhesive sticks out of the outer periphery of the plaster body 5, this adhesive does not contact the packaging film 7x. As a result, the plaster 2 can be easily removed from the packaging bag 1.
摘要:
An adhesive patch for percutaneous fentanyl administration which is easily produced, has long-term continuity, and is excellent in adhesion and conformability to the skin. The adhesive patch comprises a backing layer and a pressure-sensitive adhesive layer formed on one side thereof, wherein the pressure-sensitive adhesive layer comprises fentanyl as an active ingredient, a pressure-sensitive adhesive base, and a tackifier resin, the pressure-sensitive adhesive base comprising polyisobutylene and a styrene/isoprene/styrene block copolymer, the proportion of the polyisobutylene in the adhesive base being, 8 to 15 wt. %, and the ratio of the concentration of the polyisobutylene to that of the styrene/isoprene/styrene block copolymer being from 2:3 to 3:2.
摘要:
The present invention relates to a patch which is free from any migration of a drug into a substrate and has favorable anchoring properties between the substrate and adhesive layer, in which the drug containing adhesive layer firmly adheres onto the substrate and which gives no adhesion residue when applied to the skin and then peeled off. Namely, a patch comprising a substrate made of a polyester-based film and a drug-containing adhesive layer laminated thereon wherein the surface roughness (also known as “the central line mean roughness” or “Ra”) of the polyester-based film surface in the side in contact with the adhesive layer is from 0.05 to 0.8 μm is provided.
摘要:
The patch-containing pouch 100 of the present invention is a pouch 1 housing in its interior a patch 2 which has a pressure-sensitive adhesive layer 22 laminated on at least one side of a support 21 and has a release film 23 attached to the pressure-sensitive adhesive layer 22, wherein the pressure-sensitive adhesive layer 22 contains a drug represented by general formula (1) or a pharmaceutically acceptable salt thereof, and at least a portion of the inner surface 31a or 31b of the pouch 1 in contact with the patch 2 is made of polyacrylonitrile. [where R represents 2-isopropoxyethoxymethyl, carbamoylmethyl or 2-methoxyethyl.]
摘要:
A patch comprising a backing layer and an adhesive layer disposed on the backing layer and compounded with an adhesive agent and oxybutynin and/or a pharmaceutically acceptable salt thereof, wherein the adhesive agent comprises an acrylic polymer substantially free of both carboxyl group and hydroxyl group and a rubber polymer, in which weight ratio of content of the acrylic polymer to content of the rubber polymer is from 1:4 to 1:19.
摘要:
The present invention relates an adhesive patch comprising a backing layer and an adhesive layer that contains a drug, wherein the adhesive layer contains a mixed adhesive base containing a hydrocarbon rubber and a silicon-containing polymer. The adhesive patch of the invention shows extremely superior skin absorbability of a drug in a preparation, reduced skin irritation, and excellent aging stability of the drug in the preparation, and can achieve easiness of drug-taking methods and improvement in compliance.
