  • Publication number: 20230390214
    Abstract: An object is to provide an adhesive patch that is excellent in both percutaneous absorbability of a drug and adhesiveness to the skin. An adhesive patch of the present invention includes a backing and an adhesive layer integrally laminated on one side of the backing, the adhesive layer including a drug, levulinic acid, and an acrylic adhesive including an acrylic polymer (A) containing a vinyl-based monomer (I) moiety having a solubility parameter of 9 (cal/cm3)1/2 or more. According to the present invention, it is possible to provide an adhesive patch that is excellent in both percutaneous absorbability of a drug and adhesiveness to the skin.

  • Patent number: 9173855
    Abstract: Disclosed is a patch which is a formulation including deposited clonidine crystals and provides stable transdermal absorbability even after storage at varying temperatures. The patch disclosed includes a backing and a medicated layer integrally superposed on one surface of the backing. The medicated layer contains: 5 to 30% by weight of clonidine including clonidine in a crystallized state; 25 to 90% by weight of a macromolecular base (A) having a viscosity-average molecular weight of 800,000 or larger; and 5 to 60% by weight of a liquid additive capable of dissolving the clonidine. The weight ratio of the liquid additive to the macromolecular base (A) [the liquid additive/the macromolecular base (A)] is 0.1 to 2.0.
