Abstract: A method for storing a transdermally/transmucosally absorbable preparation, comprising keeping a transdermally/transmucosally absorbable preparation enclosed in a container in a low oxygen atmosphere, the transdermally/transmucosally absorbable preparation comprising a drug whose molecule has an amino group substituted with a lower alkyl group.

Abstract: An adhesive patch containing a non-steroidal anti-inflammatory agent, comprising a support and an adhesive layer laminated on this support, wherein the adhesive layer contains a non-steroidal anti-inflammatory agent having a carboxyl group or its salt, and polyethylene glycol having an average molecular weight of 1000 or more.

Abstract: Percutaneously absorbable preparations (preferably nonaqueous ones, particularly matrix-type patches or ointment), containing salt-form acidic drugs and characterized by being improved in the percutaneous absorbability of the drug by the incorporation of an addition salt of a basic substance therewith and by being lowly irritant to the skin; and a percutaneous absorption accelerator for salt-form acidic drugs, containing an addition salt of a basic substance.

Abstract: A percutaneous pharmaceutical preparation for external use containing a nonsteroidal antiinflammatory analgesic. It is effective in inhibiting, with higher certainty, the hypersensitivity to light attributable to the phototoxicity and photoallergy of nonsteroidal antiinflammatory analgesics. It can sufficiently produce the effects of the nonsteroidal antiinflammatory analgesic while preventing the pharmaceutical preparation from being altered with time by the incorporation of a dibenzoylmethane derivative as a UVA absorber. The percutaneous pharmaceutical preparation for external use comprises, as essential ingredients, a nonsteroidal antiinflammatory analgesic, a dibenzoylmethane derivative, and one or more members selected among polyhydric alcohol/fatty acid esters, higher fatty acid esters, and crotamiton.

Abstract: An adhesive patch comprising a substrate and a pressure-sensitive adhesive base, wherein the pressure-sensitive adhesive base comprises a rubbery polymer having double bonds in the main chain and a nonsteroidal anti-inflammatory analgesic and contains a UVA screening agent and/or UVB screening agent as a stabilizer for the rubbery polymer. The adhesive patch is excellent in the stability of the pressure-sensitive adhesive base and in drug infiltration into the skin.

Abstract: With the purpose of providing patches which do not cause photodecomposition of drugs even when exposed to the direct rays of the sun and which exhibit satisfactory drug effects and are excellent in physical properties and stability of pharmaceutical preparations, the invention provides a patch comprising a polyester substrate and a pressure-sensitive adhesive layer formed on one surface of the substrate and containing a nonsteroidal anti-inflammatory drug (NSAID) wherein the substrate contains a hydroxyphenylbenzotriazole derivative represented by the general formula (1): wherein R1 and R2 are each independently hydrogen or C1-8 alkyl; and X is halogen atom.

Abstract: An adhesive patch containing a non-steroidal anti-inflammatory agent, comprising a support and an adhesive layer laminated on this support, wherein the adhesive layer contains a non-steroidal anti-inflammatory agent having a carboxyl group or its salt, and polyethylene glycol having an average molecular weight of 1000 or more.

Abstract: A transdermal patch comprising a backing 2 and an adhesive layer 3 laminated on the backing 2, wherein the adhesive layer 3 comprises a rosin-based resin and petroleum resin as a tackifier, the total compounding amount of the rosin-based resin and the petroleum resin is in a range of 15% by mass to 50% by mass, and compounding amount of the petroleum resin is ? times by mass to 4 times by mass as that of the rosin-based resin.
