MANUFACTURING APPARATUS OF TRANSDERMAL ABSORPTION PREPARATION
A manufacturing apparatus of a transdermal absorption preparation, comprising an adhesive sheet supplying part A to feed out a band-like first adhesive sheet 3 into a runway, wherein the adhesive sheet has at least an adhesive layer comprising an adhesive and a liquid component compatible with the adhesive, a drug liquid application part B to apply a given amount of a drug liquid to an adhesive face 2b, and a traveling section C for impregnation which is set in the runway after the drug liquid application part B, during which the adhesive sheet is run for a period necessary for the applied drug liquid to soak into the adhesive layer without contact of the drug liquid coated face of the adhesive layer with other members.
The invention provides an adhesive preparation including a backing, and a pressure-sensitive adhesive layer which contains a drug and is disposed on at least one side of the backing; in which the backing includes a polyester film having a thickness of 0.5 to 6.0 µm, and a polyester nonwoven fabric directly bound to the film. The pressure-sensitive adhesive layer preferably is directly or indirectly laminated on the nonwoven-fabric side of the backing. The adhesive preparation of the invention is flexible enough to comply to the skin and has reduced skin irritation and high stability.
In the adhesive pharmaceutical preparation of the invention, a pressure- sensitive adhesive layer is laminated on one side of the backing. The pressure-sensitive adhesive layer contains a branched monoalcohol having from 12 to 28 carbon atoms, a drug which is liquid at room temperature or around room temperature (in which, free base of bisoprolol is excluded) and a polyisobutylene pressure-sensitive adhesive. Accordingly, compatibility of the polyisobutylene pressure-sensitive adhesive with the drug can be specifically increased. As a result, not only it becomes possible to increase blending amount of the drug but also bleed of the drug from the pressure- sensitive adhesive layer can be suppressed and, what is more, the pressure-sensitive adhesion characteristics sufficient from the practical point of view can be obtained.
A percutaneous absorption-type pharmaceutical preparation containing a sublimation drug is provided, where from a plaster layer, a drug is released as volatile substance with a lapse of time, but the released drug has no adverse effect on the handling of the preparation, and the quality of the preparation is maintained in storage over a long period of time. A percutaneous absorption-type pharmaceutical preparation, which comprises: a support comprising a plastic film and a nonwoven fabric; and a plaster layer containing a sublimation drug, wherein the plastic film and the nonwoven fabric are laminated with an adhesive having a glass transition temperature of 10°C or higher, and the plaster layer is laminated on opposite side of the plastic film surface that the nonwoven fabric is laminated with.
The present invention provides an adhesive capable of affording an adhesive layer showing reduced stickiness, reduced cohesive failure and the like. An adhesive containing a copolymer obtained by copolymerizing monomers containing a (meth)acrylic acid alkyl ester as a main component, and a vinyl monomer having a hydroxyl group and/or a carboxyl group and which has an average molecular radius of not less than 70 nm as measured by a multi angle laser light scattering method.
An astrocyte-specific drug carrier containing a retinoid derivative and/or a vitamin A analog as a constituent; a drug delivery method with the use of the same; a drug containing the same; and a therapeutic method with the use of the drug. By binding a drug carrier to a retinoid derivative such as vitamin A or a vitamin A analog or encapsulating the same in the drug carrier, a drug for therapeutic use can be delivered specifically to astrocytes. As a result, an astrocyte-related disease can be efficiently and effectively inhibited or prevented while minimizing side effects. As the drug inhibiting the activity or growth of astrocytes, for example, a siRNA against HSP47 which is a collagen-specific molecule chaperone may be encapsulated in the drug carrier. Thus, the secretion of type I to type IV collagens can be inhibited at the same time and, in its turn, fibrosis can be effectively inhibited.
