  • Patent number: 10022336
    Abstract: A patch containing free ropinirole (ropinirole in free form) in an adhesive base is provided, in which the patch exhibits favorable and continuous transdermal absorbability, high drug stability, and excellent adhesiveness. A transdermal absorption patch includes free ropinirole added to an adhesive base that contains a styrene-isoprene-styrene block copolymer (SIS), one or two or more tackifier resins containing a rosin-based resin, and a softener. The transdermal absorption patch is characterized in that the compounding ratio of the rosin-based resin to the free ropinirole represented as the ratio of the weight of the combined rosin-based resin to the free ropinirole is 3.5 to 8.0. In particular, a ropinirole-containing patch wherein the rosin-based resin is a hydrogenated rosin glycerol ester and the softener is liquid paraffin is provided.

  • Patent number: 9119861
    Abstract: An adhesive patch is provided in which piroxicam is formulated as a non-steroidal anti-inflammatory analgesic. In particular, provided is a piroxicam-containing transdermally absorbable adhesive patch in which an absorption promoter to piroxicam is formulated to achieve high anti-inflammatory and analgesic effects without inhibiting releasing of these drugs. The piroxicam-containing transdermally absorbable adhesive patch contains piroxicam as a medicinal component and oxybuprocaine or a pharmaceutically acceptable salt thereof as an absorption promoter. In the piroxicam-containing transdermally absorbable adhesive patch, the content of piroxicam is from 0.1% to 5% by weight to the total weight of a drug-containing plaster and the content of oxybuprocaine or the pharmaceutically acceptable salt thereof is from 1% to 30% by weight to the total weight of the drug-containing plaster.

  • Patent number: 8932626
    Abstract: An adhesive patch is a felbinac-containing transdermally absorbable preparation substantially free of a solubilizer for felbinac in a final preparation but still having high releasing of felbinac. The adhesive patch in which lidocaine and felbinac are formulated has the releasing of felbinac without losing the releasing of lidocaine. The felbinac-containing transdermally absorbable adhesive patch contains felbinac as an active component and lidocaine or a pharmaceutically acceptable salt thereof as an absorption promoter. In particular, the content of felbinac is from 0.1% to 10% by weight to the total weight of the drug-containing plaster and the content of lidocaine or the pharmaceutically acceptable salt thereof is from 0.01% to 20% by weight to the total weight of the drug-containing plaster.
