摘要:
A patch agent of the present invention comprises a support, and an adhesive layer laid on the support and containing an adhesive base and a drug, wherein the adhesive base contains an acrylic polymer substantially having no carboxyl and no hydroxyl in molecules thereof, and a rubber-based polymer, so as to achieve sufficiently high skin permeability of the drug and preparation properties. Accordingly, the present invention enables administration of the drug through skin to be implemented with drug administration effect at a sufficiently high level and on a stable basis.

摘要:
The present invention provides a cover material 10, adapted to be attached to skin in a manner covering over the entirety of a patch 20, comprising a pressure-sensitive adhesive layer 12 on one side of a support 11, wherein said patch 20 comprises a drug-containing layer 22 for contacting with the skin, said layer being provided on a support film 21 with a thickness of 12-30 μm, and wherein the cover material 10 is adapted to be attached to said support film 21 and a region of the skin around said patch 20 in such a manner that the pressure-sensitive adhesive layer 12 contacts with the edges of the drug-containing layer 22, and the pressure-sensitive adhesive layer 12 comprises a pressure-sensitive adhesive obtained by polymerizing vinyl acetate or N-vinyl-2-pyrrolidone and a (meth)acrylic acid alkyl ester with a C8 alkyl group as essential monomer components. According to the invention, it is possible to provide a cover material capable of reducing irritation to an affected area such as skin when a patch employing a drug such as pergolide mesylate is covered and affixed to the affected area.

It is intended to provide pergolide-containing transdermal preparations having reducreduced side effects and exerting sufficient therapeutic effects. Namely, a pergolide-containing transdermal preparation which is capable of achieving a plasma AUC ratio of pergolide or the like to at least one pergolide metabolite of 1:0.5 to 1:5; and/or transdermal preparation containing pergolide and/or a pharmaceutically acceptable salt thereof which is capable of achieving a ratio (A/B) of the maximum plasma level (A) of pergolide and/or a pharmaceutically acceptable salt thereof to the plasma level (B) thereof in the next administration of less than 2.
摘要:
A tape formulation for percutaneous administration containing fentanyl which comprises fentanyl or a salt thereof, a pressure sensitive adhesive and sodium acetate, is disclosed. The salt of fentanyl is preferably fentanyl citrate. The tape formulation of the present invention is little irritation to the skin and excellent in the percutaneous permeation of fentanyl and has a high stability even after the passage of time.

摘要:
A patch for transdermal administration having a sufficiently high transdermal permeation property of a COX-2 inhibitor to exert a superior antiinflammatory effect, the patch for transdermal administration comprising a backing and an adhesive layer which is placed on at least one side of the backing and comprises an adhesive base agent and a drug, wherein the drug is valdecoxib or a pharmaceutically acceptable salt thereof.
摘要:
A matrix type patch formulation which comprises an adhesive layer containing a physiological active substance, an organic acid, a hydrophobic high molecular material, a tackifying resin, a plasticizer and an absorption enhancer, is disclosed. The adhesive layer preferably contains 0.1 to 20% (w/w) of the physiological active substance, 0.01 to 15% (w/w) of the organic acid, 15 to 60% (w/w) of the hydrophobic high molecular material, 10 to 70% (w/w) of the tackifying resin, 10 to 60% (w/w) of the plasticizer and 0.01 to 20% (w/w) of the absorption enhancer. The organic acid is preferably an aliphatic carboxylic acid, an aromatic carboxylic acid, an alkyl sulfonic acid, an alkyl sulfonic acid derivative, cholic acid derivative or a water-soluble inorganic salt thereof. The matrix type patch formulation of the present invention can increase the percutaneous absorbability of the physiological active substance and is extremely reduced in skin irritation.
