Abstract

PURPOSE: A patch preparation for treatment of insect-bitten part is provided, which prevents getting worse of the affected part by blocking insect-bitten part from the exterior, and makes medicines can be work for a long time. CONSTITUTION: The patch preparation for treatment of insect-bitten site is comprised of: a supporting body(1); a layer containing medicines for insect-bitten part(2) showing smaller surface than the supporting body(1)(e.g., non-woven fabric, cotton fabric, woven fabric, mono-layered film, multi-layered laminate film, etc); an adhesive layer(3)(e.g., acrylic resin containing aliphatic alcohol and alkyl metacrylate ester) beside the layer containing medicines for insect-bitten part(2) on the supporting body(1); a separating sheet(4) on the layer containing medicines for insect-bitten part(2) and the adhesive layer(3). The adhesive layer(3) can contain resins, plasticizer, filler and anti-oxidant optionally, and which can also contain organic high molecular particles and/or inorganic substances to improve adhesive property.

Description

Patch preparation for curing a part bitten by insect}

The present invention relates to a patch formulation for treating an insect bite site.

The term 'worm bite site' is used herein to refer to parts of the body that are stung by bees or mosquito bites.

In general, a method of applying a liquid or creamy agent to the affected area is used to treat the bite site. However, these preparations are scratched consciously or unconsciously because of the itching of the bite applied to it, as a result of the deterioration of the affected area is not easily produced, and in severe cases, often hospitalized, there is also a problem that the bite site Liquid or creamy formulations applied to the product are often evaporated or erased and have to be applied frequently.

Accordingly, an object of the present invention is to provide a new formulation capable of effectively treating an insect bite site without the above problem.

1 is a view schematically showing the structure of a patch preparation for insect bite treatment according to the present invention.

Explanation of symbols on the main parts of the drawings

1: support

2: insect bite site treatment agent-containing layer

3: adhesion layer

4: release paper

According to the present invention for solving the above problems there is provided a patch for insect bite site treatment characterized in that the insect bite site treatment is contained.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 shows a patch for insect bite treatment according to an embodiment of the present invention. The patch agent shown is a support (1), a bite-site therapeutic agent-containing layer (2) having a smaller area than the support (1), stacked on the inside of the support, and the support (1) outside the therapeutic agent-containing layer (2) The adhesive layer 3 and the release paper 4 laminated | stacked on are laminated | stacked.

As the support 1, the support used for the conventional patch agent can be used. For example, a single layer film or a multilayer laminate film may be used for materials having good permeability to air or moisture such as nonwoven fabric, cotton cloth, and woven fabric, polyethylene terephthalate, polyurethane, polyethylene, polypropylene, and aluminum treated polyethylene. If necessary, the nonwoven fabric or cotton cloth may be laminated with a plastic film having no moisture permeability.

Although not particularly limited, the insect bite site treatment-containing layer 2 may be configured by loading the bite site treatment on a separate support or by directly loading the bite site treatment on the support 1. have. The insect bite site treatment may be a conventional one well known in the art, the amount may be sufficient to achieve the desired result.

The adhesive base material which comprises an adhesive layer can also use the adhesive agent used for the conventional patch agent. For example, acrylic resin can be used. (Co) polymer of a C4-18 aliphatic alcohol and a (meth) acrylic acid alkyl ester or a (co) polymer of (meth) acrylic acid alkylester having an alkyl group of 4-18 carbon atoms or a monomer having different functionalities An adhesive resin which is a polymer of may be used. Examples of the (meth) acrylic acid copolymer include butyl acrylate, isobutyl acrylate, hexyl acrylate, octyl acrylate, 2-ethylhexyl acrylate, isooctyl acrylate, decyl acrylate, isodecyl acrylate and lauryl acrylate. , Stearyl acrylate, methyl methacrylate, ethyl methacrylate, butyl methacrylate, isobutyl methacrylate, 2-ethylhexyl methacrylate, isooctyl methacrylate, decyl methacrylate and the like. Moreover, as said functional monomer, the monomer which has a hydroxyl group, the monomer which has a carboxyl group, the monomer which has an amide group, etc. can be used. As a monomer which has a hydroxy group, 2-hydroxyethyl (meth) acrylate, hydroxypropyl (meth) acrylate, etc. are mentioned. As a monomer which has a carboxyl group, (alpha)-(beta) unsaturated carboxylic acids, such as acrylic acid and methacrylic acid; Maleic acid monoalkyl esters such as butyl maleate; There are maleic acid, fumaric acid, crodonic acid and the like, and maleic anhydride can also obtain a (co) polymer in the same form as maleic acid. As a monomer which has an amide group, Alkyl (meth) acrylamide, such as acrylamide, dimethyl acrylamide, and diethyl acrylamide; Alkyl ethyl methylol (meth) acrylamides such as butoxymethyl acrylamide and ethoxymethyl acrylamide; Diacetone acrylamide; Vinylpyrrolidone; Dimethylaminoacrylate and the like. Copolymer monomers other than the above include vinyl acetate, styrene, α-methylstyrene, acrylonitrile, ethylene, propylene, butadiene and the like.

In the said adhesive agent, if necessary, various compounding agents, For example, tackifiers, such as rosin type resin, polyterpene resin, coumarodene resin, petroleum resin, terpene phenol resin; Plasticizers, fillers, antioxidants, etc., such as liquid polybutene, mineral oil, lanolin, liquid polyisoprene, and liquid polyacrylate, can be added. In addition, organic polymer fine particles such as cellulose, polyethylene, polyamide, polypropylene, polyethylene terephthalate, alginic acid, hyaluronic acid, chitin and derivatives thereof and / or zinc oxide, calcium oxide, silica, kaolin, talc, You may mix | blend inorganic substances, such as titanium oxide.

The formulation of the present invention may be constituted by applying the pressure-sensitive adhesive containing the insect bite site treatment to the support by excluding the therapeutic agent-containing layer 2 described above.

Patch preparation for insect bite site treatment of the present invention as described above can prevent the deterioration of the affected area by scratching by blocking the insect bite site from the outside, and has the advantage of being able to continuously operate the therapeutic agent for a long time It is a novel useful invention.
