摘要:
The present invention provides a percutaneously absorbable preparation comprising 2-[(1-benzylpiperidin-4-yl)methyl]-5,6-dimethoxyindan-1-one and/or a hydrochloride thereof wherein the percuneously absorbable preoaration is able to administer to a patient such that Cmax per unit surface area of the percutaneously absorbable preparation is 0.025 to 0.5 ng/ml·cm2 in a plasma concentration profile.
摘要:
[Object] By suppressing coloring of an adhesive preparation containing donepezil, a naturally colored appearance is realized.[Solution] In a method for suppressing coloring of an adhesive preparation having a support and a pressure-sensitive adhesive layer, which comprises a pressure-sensitive adhesive and donepezil in the pressure-sensitive adhesive layer, ascorbic acid, a metal salt or an ester thereof and metal metabisulfite salt are contained in the pressure-sensitive adhesive layer. This method preferably has: a step of preparing a mixture comprising the pressure-sensitive adhesive, the donepezil, the ascorbic acid, a metal salt or an ester thereof, and the metal metabisulfite salt; and a step of film-forming the pressure-sensitive adhesive layer by applying the mixture to the surface of the support.
摘要:
[Object] Discoloration, over time, of a donepezil-containing adhesive preparation is suppressed.[Solution] At least one species of stabilizer selected from the group consisting of ascorbic acid, a metal salt or an ester thereof, isoascorbic acid or a metal salt thereof, ethylenediamine tetraacetic acid or a metal salt thereof, 2-mercaptobenzimidazole, 3(2)-t-butyl-4-hydroxyanisole, 2,6-di-t-butyl-4-methylphenol, tetrakis[3-(3′,5′-di-t-butyl-4′-hydroxyphenyl)propionic acid]pentaerythritol, (±)-α-tocopherol, (±)-α-tocopherol acetate, rutin, hypophosphorous acid, a metal metabisulfite salt and a metal salt of hydroxymethanesulfinic acid, is blended in a pressure-sensitive adhesive layer containing a pressure-sensitive adhesive and donepezil.
摘要:
A donepezil-containing patch preparation is provided whereby production of donepezil-related substances in the pressure-sensitive adhesive layer is suppressed. A stabilizer comprising at least one or more species selected from the group consisting of ascorbic acid, metal salts or esters thereof, isoascorbic acid or metal salts thereof, ethylenediamine tetraacetic acid or metal salts thereof, cysteine, acetylcysteine, 2-mercaptobenzimidazole, 3(2)-t-butyl-4-hydroxyanisole, 2,6-di-t-butyl-4-methylphenol, tetrakis[3-(3′,5′-di-t-butyl-4′-hydroxyphenyl)propionic acid]pentaerythritol, 3-mercapto-1,2-propanediol, tocopherol acetate, rutin, quercetin, hydroquinone, metal salts of hydroxymethanesulfinic acid, metal metabisulfite salts, metal sulfite salts and metal thiosulfate salts is blended in a donepezil-containing pressure-sensitive adhesive layer provided on at least one side of a support.
