20100227932 | Patch - A Bisoprolol patch, wherein the skin penetration rate of Bisoprolol after 24 hours is 15 to 60% of the maximum skin penetration rate thereof, shows a little difference between the maximum level of the concentration in blood and the minimum level thereof in repeated administration and, therefore, scarcely exhibits side effects. Moreover, it achieves the quick development of the drug effect owing to the stabilization of the concentration in blood within a short time. | 09-09-2010 |
20110027365 | Patch Formulation For External Use - 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. | 02-03-2011 |

20080226697 | Patch for External Use with Elevated Content of Absorption Promoter in Pressure-Sensitive Adhesive Base - 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. | 09-18-2008 |
20090012181 | Patch - A Bisoprolol patch, wherein the skin penetration rate of Bisoprolol after 24 hours is 15 to 60% of the maximum skin penetration rate thereof, shows a little difference between the maximum level of the concentration in blood and the minimum level thereof in repeated administration and, therefore, scarcely exhibits side effects. Moreover, it achieves the quick development of the drug effect owing to the stabilization of the concentration in blood within a short time. | 01-08-2009 |
20090068252 | Transdermal Absorption Preparation - A transdermal absorption preparation having a support and a pressure-sensitive adhesive layer consisting of multiple layers, wherein the pressure-sensitive adhesive layer comprises a drug-retaining layer containing a drug and an acrylic pressure-sensitive adhesive and a skin adhesion layer containing a styrene-isoprene-styrene block copolymer. This preparation can continuously release bisoprolol at a constant concentration. Moreover, it can be easily produced. | 03-12-2009 |
20090246263 | Adhesive preparation - A patch preparation having a backing layer and a drug layer laminated on the backing layer; wherein the drug layer contains an adhesive containing at least one compound selected from the group consisting of fentanyl and pharmaceutically acceptable salts thereof, polyisobutylene, and a silicon-containing polymer; and a mass ratio of the polyisobutylene and the silicon-containing polymer in the adhesive is 20:1 to 7:3. | 10-01-2009 |
20090274747 | Pressure-Sensitive Adhesive Base and Medical Adhesive Patch Including the Pressure-Sensitive Adhesive Base - A pressure-sensitive adhesive base which contains the liquid organic ingredient and which, despite this, has moderate pressure-sensitive adhesion properties (tackiness and cohesive force) and causes no bleeding. It hardly injures the keratin of the skin and is inhibited from irritating the skin. The pressure-sensitive adhesive base comprises the following ingredients (A) to (C): (A) a copolymer comprising units of a monomer containing a carboxy group and units of a (meth) acrylic ester; (B) one or more, liquid or semisolid organic compounds which are compatible with the copolymer of the ingredient (A); and (C) at least one member selected among polyvalent-metal oxides and polyvalent-metal hydroxides, the total content of the ingredient (C) being 0.001-5 mass % based on the whole pressure-sensitive adhesive base. The adhesive base contains substantially no water. | 11-05-2009 |
