  • Patent number: 7939100
    Abstract: The present invention provides a tulobuterol adhesive patch comprising (a) a support, (b) an acrylic pressure-sensitive adhesive layer containing the percutaneously absorbing drug tulobuterol and if necessary a lipophilic oily plasticizer, and (c) a release liner, laminated in that order, wherein the acrylic pressure-sensitive adhesive is a copolymer obtained by copolymerizing an acrylic monomer which is acetoacetoxyalkyl (meth) acrylate with one or more other vinyl monomers, to yield a tulobuterol adhesive patch with excellent release and skin permeability of tulobuterol from the pressure-sensitive adhesive layer, low skin irritation and excellent safety.

  • Publication number: 20070196455
    Abstract: It is an object of the invention to provide a crosslinkable pressure-sensitive adhesive for skin that exhibits satisfactory adhesion and releasability for human skin and low irritation to skin, and a crosslinkable pressure-sensitive adhesive sheet for skin that is suitable for medical and cosmetic use, as well as to provide a composition for production of a crosslinkable pressure-sensitive adhesive for skin that has superior storage properties and is suitable for preparation of the crosslinkable pressure-sensitive adhesive for skin. The crosslinkable pressure-sensitive adhesive for skin of the invention is formed by 100 parts by weight of an acrylic copolymer (copolymer A) comprising a (meth) acrylic acid alkyl ester as the main constituent component and 3-45 wt % diacetoneacrylamide as an essential constituent component, and containing no free carboxyl groups, and 0.

  • Patent number: 6039971
    Abstract: A composition for a skin patch including a synthetic polymer gel prepared by reacting a water-soluble polymer of an aliphatic carboxylic acid or a salt thereof with a sparingly soluble aluminum compound, an organic acid containing a hydroxyl group in its molecule as a reaction accelerator, and an ethylenediamine compound as a reaction inhibitor in the presence of water at a pH of 4.0 to 6.1. The composition can homogeneously gel at any crosslinking rate and does not cause any change in quality with the lapse of time.

  • Patent number: 5478568
    Abstract: A butyrophenone transdermal composition which comprises the following components (a) to (f):(a) a water-soluble polymer which is constituted by a monomer containing, partly or wholly, aliphatic carboxylic acid having a polymerizable double bond or a salt of the carboxylic acid,(b) a cross linking agent,(c) a cross linking promoter,(d) water,(e) a butyrophenone drug, and(f) a solvent for the butyrophenone drug (e), as essential components. The pH of the composition is adjusted to fall in the range of 5.5 to 8.0.With the composition of the invention, the concentration of the active component butyrophenone in blood can be controlled. The composition is capable of exhibiting its primary action, antiemetic action, without causing rash in the skin and with less adverse side effects.
