Patent number: 10376474Abstract: A patch for external use which has a laminate structure comprising a substrate and a pressure-sensitive adhesive layer which contains a styrene/isoprene/styrene block copolymer as the base and further contains a tackifier resin consisting of a rosin resin and at least one other tackifier resin, a softening agent consisting of polybutene and liquid paraffin, a fatty acid ester, and fentanyl, characterized in that the weight ratio of the rosin resin to fentanyl is 1 to 5, the weight ratio of the rosin resin to the whole tackifier resin is 0.1 to 0.6, and the tackifier resin accounts for 30 to 60 wt % of the whole pressure-sensitive adhesive layer. The patch is excellent in the permeation of fentanyl through the skin and in storage stability, and is weak in irritation to skin.Type: GrantFiled: November 8, 2016Date of Patent: August 13, 2019Assignee: TEIKOKU SEIYAKU CO., LTD.Inventors: Kunihiko Matsushita, Mamoru Naruse, Kenichi Hattori

Patent number: 10143662Abstract: Disclosed is a fentanyl-containing adhesive preparation for external use, wherein an adhesive layer is laminated on a supporting body. The adhesive layer contains SIS, a tackifier resin that is composed of a rosin resin and terpene resin, and a softener that is composed of a plybutene and a liquid paraffin. The adhesive layer also contains fentanyl as an active ingredient. The fentanyl-containing adhesive preparation for external use has excellent skin permeation of fentanyl and high preparation stability, without suffering from crystallization of fentanyl during storage.Type: GrantFiled: May 31, 2016Date of Patent: December 4, 2018Assignee: TEIKOKU SEIYAKU CO., LTD.Inventors: Mamoru Naruse, Kenichi Hattori, Kunihiko Matsushita

Publication number: 20170112780Abstract: Since treatment effects of conventional external preparations were not satisfactory, it is aimed to provide a novel external preparation that is excellent in drug permeability to nail, capable of fully exhibiting effects of an antifungal drug, and effective for treatments of diseases such as nail mycosis and nail candidiasis, particularly, treatments for nail tinea. The external preparation of this invention is a pharmaceutical composition for nail characterized by containing an antifungal drug, alkylpyrrolidone or a derivative thereof, and a crosslinking hydrogel.Type: ApplicationFiled: January 6, 2017Publication date: April 27, 2017Applicant: TEIKOKU SEIYAKU CO., LTDInventors: Tomohiro ISHIMA, Mamoru NARUSE, Hideo KANEDA, Kazuo KANAI, Takashi SEKINE, Shinichi OTA, Tomonari YOSHIMURA
