Description

本発明は、経皮吸収貼布剤関するものである。さらに詳細には、離型フィルムを使用しない経皮吸収貼布剤であるため、廃棄物量を減らすことができ、コスト的にも安価であり、かつ、経皮吸収貼布剤を使用する時の作業性に優れた経皮吸収貼布剤関するものである。 The present invention relates to a percutaneous absorption plasters. More specifically, since it is a transdermal absorption patch that does not use a release film, the amount of waste can be reduced, the cost is low, and when the transdermal absorption patch is used. it relates to the excellent percutaneous absorption plasters workability.

従来より、経皮吸収貼布剤には、経皮吸収剤層(薬効成分を含有した粘着剤層)の保護のために、貼布剤用離型紙や貼布剤用離型フィルムが使用されている。貼布剤用離型紙の場合、経皮吸収剤への紙粉の混入が避けられないことや、経皮吸収剤の薬効成分を離型紙が吸着してしまう可能性があることなどから、近年は、貼布剤用離型紙から貼布剤用離型フィルムへの切り替えが進んでいる。   Conventionally, a release paper for a patch or a release film for a patch is used for a transdermal absorption patch for the protection of a transdermal absorbent layer (adhesive layer containing a medicinal component). ing. In the case of release paper for patch, in recent years, it is inevitable that paper powder is mixed into the transdermal absorbent, and the release paper may absorb the medicinal properties of the transdermal absorbent. Has been switched from release paper for patch to release film for patch.

貼布剤用離型フィルムに関して、特許文献1には、基材のポリエチレンテレフタレートフィルムに、シリコーン処理した貼布剤用剥離フィルムが提案されている。また、特許文献2には、基材にポリエチレンナフタレートフィルムを用いた貼布剤用離型フィルムが提案されている。ところが、透明な樹脂フィルムを基材として用いた貼布剤用離型フィルムは、経皮吸収貼布剤から剥離した後に、その貼布剤用離型フィルムが床などに落ちていても視認されず、誤ってその貼布剤用離型フィルムを足で踏んだ時に、滑って不測の事故を起こす恐れがあるなどの問題点がある。   Regarding a release film for a patch, Patent Document 1 proposes a release film for a patch that is obtained by applying a silicone treatment to a polyethylene terephthalate film as a base material. Patent Document 2 proposes a release film for a patch using a polyethylene naphthalate film as a base material. However, a release film for a patch using a transparent resin film as a base material is visually recognized even after the release film for the patch has fallen on the floor or the like after peeling from the transdermal absorption patch. However, if you accidentally step on the release film for patch, you may slip and cause an accident.

そのため、特許文献3には、基材が積層された構成であって、視認性付与機能を有する中間層を備えた貼布剤用離型フィルムが提案されている。視認性を有する中間層を設けたことにより、経皮吸収貼布剤から剥離した後に、その貼布剤用離型フィルムを床などに落とした場合にも、貼布剤用離型フィルムが落ちていることを視認できるが、貼布剤用離型フィルムの表面が平滑であったり、剥離剤塗工面が滑りやすかったりして、落ちている貼布剤用離型フィルムを拾い上げることが難しかった。特に、経皮吸収貼布剤を使用する頻度の高い高齢者や病弱な人にとっては、床面に落ちている貼布剤用離型フィルムを、前傾した姿勢を保った状態で拾い上げることが、非常に難儀であるという問題があった。   Therefore, Patent Document 3 proposes a release film for a patch having a structure in which base materials are laminated and having an intermediate layer having a visibility imparting function. By providing an intermediate layer with visibility, the release film for the patch will fall even if the release film for the patch is dropped on the floor after peeling from the transdermal absorption patch. However, it was difficult to pick up the falling release film for the patch because the surface of the release film for the patch was smooth or the surface to which the release agent was applied was slippery. . In particular, for elderly people and sick people who frequently use transdermal patches, it is possible to pick up the release film for patch that has fallen on the floor surface while maintaining a tilted posture. There was a problem that was very difficult.

一方、近年、ジェネリック医薬品の台頭や薬価の改定により、経皮吸収貼布剤の薬価が低下する傾向にあり、貼布剤用離型フィルムに対しても、より安価なものが求められている。また、社会全体として、自然環境に与える負荷を低減させることが、重要な課題となっている。貼布剤用離型フィルムは、経皮吸収貼布剤を使用する際に、剥がして廃棄される。そのため、自然環境面への配慮として、廃棄時のゴミを減容することが重要になってきている。廃棄時のゴミの減容化、および安価な貼布剤用離型フィルムを提供するために、貼布剤用離型フィルムに使用するフィルムの厚さを薄くする方策が考えられる。この場合には、床面に落とした貼布剤用離型フィルムを拾い上げる際に、貼布剤用離型フィルムの厚みが薄いために、指でつまむことが難しく、拾い上げる困難さが更に増加することが問題になる。また、経皮吸収貼布剤から貼布剤用離型フィルムを剥がし難くなるため、経皮吸収貼布剤を身体に貼付する操作性も悪化する問題があった。   On the other hand, due to the rise of generic drugs and revision of drug prices in recent years, the drug price of transdermal absorption patch tends to decrease, and a cheaper film is required for the release film for patch. . In addition, reducing the burden on the natural environment as an entire society has become an important issue. The release film for patch is peeled off and discarded when the transdermal absorption patch is used. Therefore, as a consideration for the natural environment, it is important to reduce the volume of trash at the time of disposal. In order to reduce the volume of waste at the time of disposal and to provide an inexpensive release film for a patch, it is conceivable to reduce the thickness of the film used for the release film for a patch. In this case, when picking up the release film for a patch that has been dropped on the floor surface, the thickness of the release film for the patch is thin, making it difficult to pinch with a finger, and the difficulty of picking up further increases. It becomes a problem. Moreover, since it becomes difficult to peel off the release film for the patch from the transdermal absorption patch, there is a problem that the operability of applying the transdermal absorption patch to the body also deteriorates.

The process of obtaining the transdermal absorption patch 10 in which the film 2 is laminated in order is manufactured in the order of (1) to (3). It is.
FIG. 2 is an example of the transdermal absorption patch 10 produced using the production method.

本発明に用いられる基材シート1としては、水溶性樹脂膜2が、基材シートから剥離されて転写可能であれば、特に限定されるものではなく、紙、樹脂フィルム、樹脂シートなどいずれも使用できる。紙を基材として使用する際には、基材シート1に水溶性樹脂膜2を設ける際に、水溶性樹脂膜を形成する樹脂が、基材シートにしみ込まないように、クレーコートや樹脂コート、ポリエチレンラミネートなどの目留め処理をすることが望ましい。   The substrate sheet 1 used in the present invention is not particularly limited as long as the water-soluble resin film 2 can be transferred after being peeled from the substrate sheet, and any of paper, resin film, resin sheet and the like can be used. Can be used. When using paper as a base material, when the water-soluble resin film 2 is provided on the base material sheet 1, a clay coat or resin coat is used so that the resin that forms the water-soluble resin film does not penetrate into the base material sheet. It is desirable to perform sealing treatment such as polyethylene laminate.

また、紙基材としては、クレーコート紙、アートコート紙、樹脂コート紙、グラシン紙、ポリエチレンラミネート紙などが挙げられる。また、樹脂フィルムの基材としては、ポリエチレンフィルム、ポリプロピレンフィルム、ポリエステルフィルム、ポリアミドフィルム、アクリルフィルム、ポリカーボーネートフィルム、ポリイミドフィルム、塩化ビニルフィルム、塩化ビニリデンフィルム、ポリスチレンフィルムなどの樹脂フィルムが挙げられる。樹脂シートの基材としては、ポリオレフィンシート、塩化ビニルシート、ポリエステルシート、ポリアミドシートなどが挙げられる。また、水溶性樹脂膜2を転写しやすくするため、表面にシリコーン、フッ素、ワックス、オレフィンなどの離型処理をしても良い。   Examples of the paper substrate include clay-coated paper, art-coated paper, resin-coated paper, glassine paper, and polyethylene laminated paper. Examples of the substrate of the resin film include resin films such as polyethylene film, polypropylene film, polyester film, polyamide film, acrylic film, polycarbonate film, polyimide film, vinyl chloride film, vinylidene chloride film, and polystyrene film. . Examples of the base material of the resin sheet include a polyolefin sheet, a vinyl chloride sheet, a polyester sheet, and a polyamide sheet. Further, in order to facilitate the transfer of the water-soluble resin film 2, the surface may be subjected to mold release treatment such as silicone, fluorine, wax and olefin.

また、水溶性樹脂膜2は、経皮吸収貼布剤を使用する迄は、経皮吸収貼布剤の粘着剤層3の表面を保護し、経皮吸収貼布剤を使用する時には、水溶性樹脂膜2に水を付着させることにより、水溶性樹脂膜2が溶解し、経皮吸収貼布剤の粘着剤層3が皮膚に直接接触して貼付けできる機能を有する。また、水溶性樹脂膜2を、経皮吸収貼布剤の粘着剤層3の上に、基材シートからきれいに転写させるため、薄膜に形成できる樹脂が好適である。水溶性樹脂膜2に用いられる樹脂としては、水溶性であることが必要であり、薄膜に形成できることを考慮すると分子量が大きいものが好適に用いられる。水溶性樹脂膜2を形成する水溶性樹脂としては、でんぷん、キサンタンガム、アルギン酸ナトリウム、ポリビニルアルコールなどが挙げられる。水溶性樹脂(水溶性高分子)は、人工的に重合反応で得た合成高分子物質に限られず、多糖類や蛋白質等の天然高分子物質や、これらの天然高分子物質にエーテル化、エステル化等の化学的処理を施した誘導体(半合成高分子物質)でもよい。水溶性樹脂膜2は、包装袋や手指等に触れても、粘着性や付着性のないことが好ましい。   In addition, the water-soluble resin film 2 protects the surface of the adhesive layer 3 of the transdermal absorption patch until the transdermal absorption patch is used. The water-soluble resin film 2 is dissolved by adhering water to the adhesive resin film 2, and the adhesive layer 3 of the transdermal absorption patch has a function of directly contacting the skin and sticking. Moreover, in order to transfer the water-soluble resin film 2 cleanly from the base material sheet onto the adhesive layer 3 of the transdermal absorption patch, a resin that can be formed into a thin film is suitable. The resin used for the water-soluble resin film 2 needs to be water-soluble, and a resin having a large molecular weight is preferably used in consideration that it can be formed into a thin film. Examples of the water-soluble resin that forms the water-soluble resin film 2 include starch, xanthan gum, sodium alginate, polyvinyl alcohol, and the like. Water-soluble resins (water-soluble polymers) are not limited to synthetic polymer materials obtained by artificial polymerization reactions, but include natural polymer materials such as polysaccharides and proteins, and etherification and esterification of these natural polymer materials. It may be a derivative (semi-synthetic polymer material) subjected to chemical treatment such as chemical conversion. It is preferable that the water-soluble resin film 2 does not have adhesiveness or adhesion even when it touches a packaging bag or a finger.

また、基材シート1に水溶性樹脂膜2を設ける方法としては、水溶性樹脂を溶かした溶液を基材シート1に塗布し、乾燥させるコーティング法が一般的である。コーティング方法は、特に限定されるものではなく、公知のコーティング方法を用いれば良い。具体的には、グラビアコーティング、バーコーティング、エアーナイフコーティング、リバースロールコーティング、スロットダイコーティング、スクリーン印刷などが挙げられる。   Moreover, as a method of providing the water-soluble resin film 2 on the base sheet 1, a coating method is generally used in which a solution in which a water-soluble resin is dissolved is applied to the base sheet 1 and dried. The coating method is not particularly limited, and a known coating method may be used. Specific examples include gravure coating, bar coating, air knife coating, reverse roll coating, slot die coating, and screen printing.

また、水溶性樹脂膜2の厚みは、0.1〜5μmが好適である。水溶性樹脂膜2の厚みが、0.1μmよりも薄いと、基材シート1から、経皮吸収貼布剤の粘着剤層3の上に、転写しにくかったり、粘着剤層3をうまく保護できずに粘着剤層3がはみ出したりする可能性がある。水溶性樹脂膜2の厚みが、5μmを越えると、水溶性樹脂膜2に水を付着させた時に、水溶性樹脂膜2の溶解に時間が掛り、経皮吸収貼布剤の貼付作業がし難くなる。   In addition, the thickness of the water-soluble resin film 2 is preferably 0.1 to 5 μm. If the water-soluble resin film 2 is thinner than 0.1 μm, it is difficult to transfer from the base sheet 1 onto the adhesive layer 3 of the transdermal absorption patch, and the adhesive layer 3 is well protected. There is a possibility that the pressure-sensitive adhesive layer 3 protrudes without being possible. If the thickness of the water-soluble resin film 2 exceeds 5 μm, it takes time to dissolve the water-soluble resin film 2 when water is attached to the water-soluble resin film 2, and the transdermal absorption patch is applied. It becomes difficult.

水溶性樹脂膜2に接する粘着剤層3には、経皮吸収貼布剤に一般的に使用される粘着剤を使用して良い。具体的には、ゴム系粘着剤、アクリル系粘着剤、シリコーン系粘着剤などの粘着剤に薬効成分を混合した粘着剤で、形態としてはホットメルトタイプ、溶剤タイプ、エマルジョンタイプ等がある。水溶性樹脂膜2に水分が付与されても、薬効成分を含有した経皮吸収剤層である粘着剤層3が、溶解あるいは膨潤しないよう、非水溶性の粘着剤が好ましい。粘着剤層3は、前記水溶性樹脂を少量含むものでもよいが、前記水溶性樹脂を含まないことが好ましい。
また、経皮吸収貼布剤の粘着剤層3に対する薬剤の添加量は、薬剤の種類、経皮吸収剤のサイズ、粘着剤の厚さなどを考慮して決めれば良い。
For the pressure-sensitive adhesive layer 3 in contact with the water-soluble resin film 2, a pressure-sensitive adhesive generally used for a transdermal absorption patch may be used. Specifically, it is a pressure-sensitive adhesive in which a medicinal component is mixed with a pressure-sensitive adhesive such as a rubber-based pressure-sensitive adhesive, an acrylic pressure-sensitive adhesive, or a silicone-based pressure-sensitive adhesive, and forms include a hot melt type, a solvent type, and an emulsion type. A water-insoluble adhesive is preferred so that the adhesive layer 3 which is a transdermal absorbent layer containing a medicinal component does not dissolve or swell even when moisture is applied to the water-soluble resin film 2. The pressure-sensitive adhesive layer 3 may contain a small amount of the water-soluble resin, but preferably does not contain the water-soluble resin.
The amount of drug added to the adhesive layer 3 of the transdermal absorption patch may be determined in consideration of the type of drug, the size of the transdermal absorbent, the thickness of the adhesive, and the like.

粘着剤層3の厚さは、特に限定されるものではなく、粘着剤の種類、薬効成分の添加量、皮膚への付着性などを考慮して決めれば良い。粘着剤層3を設ける方法としては、水溶性樹脂膜2を施した基材シート1の片面に、粘着剤を公知の方法により塗布し、ホットメルトタイプ以外の粘着剤ではその後乾燥させる方法、または、基布に粘着剤を公知の方法により塗布し、ホットメルトタイプ以外の粘着剤ではその後乾燥させる方法がある。   The thickness of the pressure-sensitive adhesive layer 3 is not particularly limited, and may be determined in consideration of the type of pressure-sensitive adhesive, the amount of medicinal ingredients added, the adhesion to the skin, and the like. As a method of providing the pressure-sensitive adhesive layer 3, a method of applying a pressure-sensitive adhesive by a known method on one side of the substrate sheet 1 to which the water-soluble resin film 2 has been applied, and then drying it with a pressure-sensitive adhesive other than the hot melt type, or There is a method in which a pressure-sensitive adhesive is applied to a base fabric by a known method, and a pressure-sensitive adhesive other than the hot melt type is then dried.

転写シートへの粘着剤の塗布方法、及び、基布4への粘着剤の塗布方法は、公知のコーティング方法を用いれば良い。具体的には、グラビアコーティング、バーコーティング、エアーナイフコーティング、リバースロールコーティング、スロットダイコーティング、スクリーン印刷などが挙げられる。   As a method for applying the pressure-sensitive adhesive to the transfer sheet and a method for applying the pressure-sensitive adhesive to the base cloth 4, a known coating method may be used. Specific examples include gravure coating, bar coating, air knife coating, reverse roll coating, slot die coating, and screen printing.

また、経皮吸収貼布剤の基布4は、経皮吸収貼布剤を使用する時に、薬効成分を含有した粘着剤層3の支持体となるもので、使用方法に合わせて選定すれば良く、特に限定されるものではない。従来から、経皮吸収貼布剤の用途に使用されている基布を、好適に用いることができる。具体的には、ポリオレフィンフィルム、塩化ビニルフィルム、不織布、などが使用できる。   Moreover, the base fabric 4 of the transdermal absorption patch is a support for the pressure-sensitive adhesive layer 3 containing a medicinal component when the transdermal absorption patch is used, and can be selected according to the method of use. Good, not particularly limited. Conventionally, the base fabric used for the use of a transdermal absorption patch can be used suitably. Specifically, a polyolefin film, a vinyl chloride film, a nonwoven fabric, etc. can be used.

基材シート1から、水溶性樹脂膜2を経皮吸収貼布剤の粘着剤層3の表面に転写する方法としては、次の2通りの方法がある。
(1)水溶性樹脂膜2を積層した基材シート1の、該水溶性樹脂膜2の表面に粘着剤を塗布し、必要に応じて乾燥させて形成した粘着剤層3の上に、基布4を貼合した後、その基布4を粘着剤層3及び水溶性樹脂膜2と共に、基材シート1から剥がす方法。
(2)基布4に粘着剤を塗布し、必要に応じて乾燥させて形成した粘着剤層3の上に、基材シート1の少なくとも一方の面に水溶性樹脂膜2を積層した、水溶性樹脂膜の転写シートの水溶性樹脂膜の面を貼合し、その後、基布4を粘着剤層3及び水溶性樹脂膜2と共に、基材シート1から剥がす方法。
どちらの方法を選択するかは、使用する基材シート、粘着剤、基布などの材料や、加工条件などを考慮して決めれば良い。
There are the following two methods for transferring the water-soluble resin film 2 from the substrate sheet 1 to the surface of the adhesive layer 3 of the transdermal absorption patch.
(1) On the pressure-sensitive adhesive layer 3 formed by applying a pressure-sensitive adhesive to the surface of the water-soluble resin film 2 of the substrate sheet 1 on which the water-soluble resin film 2 is laminated, and drying it as necessary. A method of peeling the base fabric 4 from the base material sheet 1 together with the pressure-sensitive adhesive layer 3 and the water-soluble resin film 2 after bonding the fabric 4.
(2) A water-soluble resin film 2 is laminated on at least one surface of the base sheet 1 on the pressure-sensitive adhesive layer 3 formed by applying a pressure-sensitive adhesive to the base cloth 4 and drying it as necessary. The surface of the water-soluble resin film of the transfer sheet of the water-soluble resin film is bonded, and then the base cloth 4 is peeled off from the base material sheet 1 together with the pressure-sensitive adhesive layer 3 and the water-soluble resin film 2.
Which method should be selected may be determined in consideration of materials such as a base sheet, an adhesive, and a base fabric to be used, processing conditions, and the like.

経皮吸収貼布剤10の使用時には、粘着剤層3の表面を覆っている水溶性樹脂膜2に水分を付けることで、水溶性樹脂膜2が水に溶け、粘着剤層3の表面を皮膚に貼合することが可能となる。本発明に係わる経皮吸収貼布剤は、粘着剤層3の表面に水溶性樹脂膜2を転写することにより、従来の経皮吸収貼布剤で必要不可欠となっていた離型フィルムまたは離型紙が不要となる。本発明に係わる経皮吸収貼布剤は、離型フィルムまたは離型紙を使用しないため、経皮吸収貼布剤を使用する時に、離型フィルムまたは離型紙を剥がす必要が無く、背中や腰などの自分で見えない所にも、経皮吸収貼布剤を一人で容易に貼合できる。また、経皮吸収貼布剤を使用する時に、離型フィルムまたは離型紙のゴミも出ない上、離型フィルムまたは離型紙が床などに落ちていても視認されず、誤ってその貼布剤用離型フィルムを足で踏んだ時に、滑って不測の事故を起こす恐れがあるなどの問題点がある。   When the transdermal patch 10 is used, water is applied to the water-soluble resin film 2 covering the surface of the pressure-sensitive adhesive layer 3, so that the water-soluble resin film 2 is dissolved in water and the surface of the pressure-sensitive adhesive layer 3 is covered. It becomes possible to paste on the skin. The transdermal absorption patch according to the present invention transfers the water-soluble resin film 2 to the surface of the pressure-sensitive adhesive layer 3, thereby releasing the release film or release film that has become indispensable in the conventional transdermal absorption patch. No paper pattern is required. Since the transdermal absorption patch according to the present invention does not use a release film or release paper, it is not necessary to peel off the release film or release paper when using the transdermal absorption patch, such as the back or waist. Even if you can't see it, you can easily paste the transdermal patch alone.
