摘要:
An external patch capable of stable prolonged release and transdemtal absorption of active ingredient hormones (estrogens and/or progestogens) contained in a pressure sensitive adhesive layer, which external patch ensures low irritation on the skin. In particular, an external patch comprising a support and, superimposed thereon, a pressure sensitive adhesive layer, characterized in that the pressure sensitive adhesive layer comprises, as indispensable components, 5 to 50 wt.% of styrene/isoprene/styrene block copolymer, 20 to 70 wt.% of tackifier resin, 10 to 60 wt.% of softener and 1 to 20 wt.% of polyvinylpyrrolidone and contains, as an active ingredient, estrogen and/or progestogen.

摘要:
Provided herein is a female hormone-containing patch wherein an active ingredient is highly soluble in a pressure-sensitive adhesive layer and the active ingredient is not adsorbed to a backing, and the patch per se can follow the irregularities on the skin surface or body movements. The patch is an external patch containing, as a female hormone, a follicular hormone estradiol and/or its derivative or a progestational hormone norethisterone and/or its derivative. The external patch comprises an acrylic pressure-sensitive adhesive containing 0.01 to 1% by weight of an isocyanate-based crosslinking agent as an essential ingredient.
摘要:
An anti-inflammatory analgesic patch which contains 4-biphenylacetic acid, which is a sparingly soluble anti-inflammatory analgesic, and two or more drug resolvents and which is hence improved in the releasability of 4-biphenylacetic acid from the base and in the sustained release thereof and is reduced in skin irritation. The patch contains as essential ingredients 5 to 50 wt.% styrene/isoprene/styrene block copolymer, 0.05 to 20 wt.% N-methyl-2-pyrrolidone, 0.1 to 20 wt.% polyethylene glycol, and 0.1 to 20 wt.% 4-biphenylacetic acid.
摘要:
Patch preparations for percutaneous absorption with the use of supports showing an appropriate strength as a patch support, which are excellent in drug barrier characteristics, compatibility with the skin, ODT effects and handling characteristics and can sustain these specific properties in a stable state over a prolonged period of time, thus ensuring good percutaneous absorption of drugs. In these patch preparation, use is made as the support of polyester film/nonwoven vinylon fabric laminates showing an elongation percentage of at least 5 % and a tensile cutting load of at least 0.5 kg/10 mm, when measured by the test method specified in JIS K6732. In particular, the thickness of the polyester film constituting the laminate supports ranges from 1.5 to 6.0 µm and the unit weight of the nonwoven vinylon fabric ranges from 3 to 12 g/m 2 .

摘要:
Patches containing isosorbide nitrate, having sufficient tackiness in the application thereof, and stabilized in the release of the drug after the application. The patches are characterized in that isosorbide nitrate is added as the active ingredient to tacky plasters containing as the essential ingredients styrene-isoprene-styrene block copolymers, rosin resins, liquid rubbers, antioxidants and oleic acid. More particularly, 15 to 25 % (w/w) of isosorbide nitrate is added to plasters containing 15 to 35 % of styrene-isoprene-styrene block copolymers, 35 to 55 % of rosin resins, 5 to 20 % of liquid rubbers, 0.1 to 2 % of antioxidants and 0.1 to 5 % of oleic acid.
摘要:
A patch containing tulobuterol in the low concentration and having the stable release-controllability, prepared by laminating an adhesive layer consisting of a rubber, an adhesive resin and a plasticizer on a backing, wherein 1 to 4 w/w % of tulobuterol in the lower concentration as an active ingredient and 0.1 to 3 w/w % of a higher fatty acid as a drug-releasing controlling agent are contained in the adhesive layer.
摘要:
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.
