Patent number: 10022336Abstract: 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.Type: GrantFiled: November 28, 2013Date of Patent: July 17, 2018Assignee: Teikoku Seiyaku Co., Ltd.Inventors: Katsuyuki Inoo, Akiko Katayama, Daiki Takano
