Patent number: 10149834Abstract: Provided is an adhesive patch containing ropinirole serving as a therapeutic drug for Parkinson's disease, with the ropinirole used being free ropinirole (ropinirole in free form) added to an adhesive base, wherein the patch exhibits favorable drug permeability and excellent drug stability. Also provided is a transdermal absorption patch using, as an adhesive base, an acrylic-based adhesive having no specific carboxyl group and having a hydroxyl group or a pyrrolidone group, with the patch including free ropinirole added to the adhesive base. Further provided is a ropinirole-containing transdermal absorption patch including a transdermal absorption promoting agent.Type: GrantFiled: May 2, 2017Date of Patent: December 11, 2018Assignee: Teikoku Seiyaku Co., Ltd.Inventors: Katsuyuki Inoo, Akiko Katayama, Daiki Takano

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

Patent number: 9205060Abstract: Provided is a transdermal absorption-type patch containing a serotonin receptor antagonist, which has a short transdermal absorption delay time (lag time), and in which the maximum transdermal permeation rate of the drug can be reached within a short time and the drug can disappear from circulating blood rapidly. That is, provided is a patch containing a serotonin receptor antagonist, wherein the patch contains an adhesive layer comprising a non-functional acrylic adhesive, a water-soluble organic amine, a fatty acid ester, and a serotonin receptor antagonist such as granisetron as an active ingredient.Type: GrantFiled: July 4, 2012Date of Patent: December 8, 2015Assignee: Teikoku Seiyaku Co., Ltd.Inventors: Takashi Kamakura, Daiki Takano
