Abstract: The invention provides a transdermal absorption preparation showing sufficient adhesiveness on adhesion to the skin, causing low skin irritation, and capable of well controlling releaseability of lidocaine. The transdermal absorption preparation contains a support and an adhesive layer formed on the support. The adhesive layer contains a drug, as well as a thermoplastic elastomer, more than 300 parts by weight of liquid paraffin per 100 parts by weight of the elastomer, not more than 10 wt % of a tackifier, lidocaine, and an organic acid.

Abstract: The invention provides an adhesive sheet for adhesion to the skin, as well as a transdermal absorption preparation containing the adhesive sheet and a drug or a pharmaceutically acceptable salt thereof in the adhesive layer of the adhesive sheet. The adhesive sheet comprises a support and an adhesive layer formed on the support, wherein the adhesive layer contains at least a thermoplastic elastomer, and more than 300 parts by weight of liquid paraffin per 100 parts by weight of the elastomer, and wherein the adhesive layer contains not more than 10 wt % of a tackifier.

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.

Abstract: It is provided the plaster of anti-inflammatory and analgesic, improving the sustained releasing of 4-biphenylacetic acid from the base adhesive material and low skin irritation, by using more than two kinds of resolvent for 4-biphenylacetic acid having low solubility in solvents. More specifically, it is provided plasters essentially containing 5–50% by weight of styrene-isoprene-styrene block copolymer, 0.05–20% by weight of N-methyl-2-pyrrolidone, 0.1–20% by weight of polyethylene glycol and 0.1–20% by weight of 4-biphenylacetic acid.

Abstract: In order to provide an external skin patch having improved painkilling effect for pains accompanied by inflammation, such as chronic arthrorheumatism, arthrosis deformans or low back pain, an external skin patch is obtained by coating a drug-containing base on a substrate; the drug-containing base comprises an adhesive gel base containing a water soluble polymeric material, a crosslinking agent, water and a humectant as essential components, and a local anesthetic and a nonsteroidal antiphlogistic analgesic agent as medicinal components.
