  • Patent number: 10098858
    Abstract: An aqueous loxoprofen-containing patch is provided, which has good stability and excellent transdermal absorption of loxoprofen. The aqueous patch includes loxoprofen or a salt thereof and triacetin. Specifically, the aqueous patch includes, based on the weight of the adhesive gel base, 0.1 to 5% by weight of loxoprofen or a salt thereof, 0.5 to 5% by weight of triacetin, 1 to 30% by weight of a water-soluble polymer, 0.01 to 5% by weight of a cross-linking agent, 10 to 90% by weight of purified water, and 0 to 20% by weight of an inorganic powder.

  • Publication number: 20160136277
    Abstract: Provided is a water-based patch that contains ketoprofen as an active ingredient, provides high transdermal absorbability of the ketoprofen, and has high safety and high storage stability. The water-based patch contains the ketoprofen, an amine, and polyethylene glycol. In the water-based patch, the added amount of the ketoprofen in a paste is 0.1 to 5% by weight, the added amount of the amine in the paste is 0.5 to 10% by weight, and the added amount of the polyethylene glycol in the paste is 5 to 30% by weight. Particularly, in the water-based patch, diisopropanolamine is used as the amine.

  • Patent number: 9120956
    Abstract: Provided is a water-based plaster in which the gel strength is maintained to an appropriate level in a step of producing the water-based plaster, and particularly in a spreading step and an aging step, and a final preparation can exhibit an optimal adhesiveness for adhering to the skin. In the water-based plaster, a water-based adhesive base containing a water-soluble polymer as a main ingredient contains a higher fatty acid which is a liquid at room temperature and a viscosity of 1,000 (mPa·s, 20° C.) or more as a crosslinking modifier. The higher fatty acid is isostearic acid, and the contained amount thereof is 1 to 10% by weight.
