  • Transdermal preparation
    Patent number: 8702664
    Abstract: By providing a non-liquid drug reservoir layer 2 having first and second principal surfaces and containing a drug and a polymer that is to be a base, a drug permeation layer 4 disposed at the first principal surface side of the drug reservoir layer 2 and being lower in permeability of the drug than the drug reservoir layer 2, and a first backing 3 with a bending resistance of 10 to 80 mm that is formed so as to cover a side surface of the drug reservoir layer, skin irritation can be reduced.
    Type: Grant
    Filed: February 9, 2010
    Date of Patent: April 22, 2014
    Assignee: Hisamitsu Pharmaceutical Co., Inc.
    Inventors: Satoshi Amano, Tomohiro Shinoda, Natsumi Kase, Keita Mori
  • Transdermal absorption preparation
    Patent number: 8524273
    Abstract: 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.
