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.
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 patch formulation for external use where a basic drug, an organic acid and an organic acid salt are combined as essential components is disclosed. The basic drug is preferably in the form of its acid addition salt. The organic acid is preferably a carboxylic acid having carbon atoms of 2 to 7, and more preferably at least one acid selected from the group consisting of acetic, lactic, tartaric, citric, malic, benzoic and salicylic acids. The organic acid salt is preferably a metal salt of a carboxylic acid, and more preferably sodium acetate.

摘要:
The invention provides a process for production of pressure-sensitive adhesive shaped products which enables proper shaping of a tacky polymer through proper control of the rate of crosslinking thereof, specifically, a process for production of pressure-sensitive adhesive shaped products which comprises mixing a polymer bearing hydroxyl or carboxyl groups with one or more crosslinking agents selected from the group consisting of metal alcoholates and boron compounds in the presence of a lower alcohol and then subjecting the obtained mixture to shaping either accompanied with or followed by thermal crosslinking.
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.]
