Description

本発明は、眼科用フィルム製剤に関する。   The present invention relates to an ophthalmic film preparation.

従来、蛍光造影診断薬として、例えばフルオレセインナトリウムなどの検査薬を含有するフローレス眼検査用試験紙が使用されている(非特許文献1)。この試験紙は、生理食塩水1滴を試験紙の薬剤含有部(橙赤色部分)に滴下した後、この薬剤含有部を結膜に接触させて薬剤を眼表面に移行させて用いる。   Conventionally, a test paper for flowless ophthalmic examination containing a diagnostic agent such as fluorescein sodium has been used as a fluorescent contrast diagnostic agent (Non-patent Document 1). This test paper is used by dropping one drop of physiological saline on the drug-containing part (orange-red part) of the test paper and then bringing the drug-containing part into contact with the conjunctiva and transferring the drug to the ocular surface.

しかし、この試験紙は、生理食塩水を滴下して使用しなければならない点で不便であり、また、生理食塩水を滴下せずに使用すれば、検査薬の眼表面への移行が不充分となり、痛みを伴うこともある。   However, this test paper is inconvenient in that it must be used by dropping physiological saline, and if it is used without dropping physiological saline, the transfer of the test drug to the ocular surface is insufficient. And can be painful.

A method comprising applying a water-soluble film coating solution containing a dye, a test agent or a local anesthetic and polyvinylpyrrolidone on a water-insoluble support.

本発明によれば、生理食塩水を滴下する必要がなく、眼表面に存在する涙液で速やかに色素、検査薬または局所麻酔薬を眼表面に移行させることができる。
また、生理食塩水を滴下する必要がないので、生理食塩水による、涙液の質や量への影響はなく、涙液層破壊時間検査への使用が可能となる。
さらに、本発明の眼科用フィルム製剤は、従来の点眼剤とは異なって重力による滴下操作(点眼操作)を必要とせず、眼科用フィルム製剤を眼表面に接触させるだけで簡便に色素、検査薬または局所麻酔薬を眼に投与することができるので、宇宙空間や無重力空間でも色素、検査薬または局所麻酔薬の眼への適正投与が可能となる。
According to the present invention, it is not necessary to add physiological saline dropwise, and a pigment, a test agent or a local anesthetic can be quickly transferred to the ocular surface with tears present on the ocular surface.
In addition, since it is not necessary to drop physiological saline, the physiological saline has no effect on the quality and quantity of tears, and can be used for the tear film destruction time test.
Furthermore, unlike the conventional eye drops, the ophthalmic film preparation of the present invention does not require a dropping operation by gravity (eye drop operation), and simply allows the ophthalmic film preparation to be brought into contact with the ocular surface, thereby providing a pigment and a test agent. Alternatively, since the local anesthetic can be administered to the eye, it is possible to appropriately administer the dye, the test agent, or the local anesthetic to the eye even in outer space or weightless space.

本実施形態の眼科用フィルム製剤10は、図1及び図2に示すように、非水溶性支持体20と、色素、検査薬または局所麻酔薬とポリビニルピロリドンとを含有する水溶性フィルム30とからなり、非水溶性支持体20の表面である上面21の一部(図1)又は非水溶性支持体20の上面21に垂直若しくは略垂直な端部23(図2)と、水溶性フィルム30とが接している。本明細書において、図1及び図2に示すような、非水溶性支持体20と水溶性フィルム30とが接している構造を「二層構造」ということがある。非水溶性支持体20は、涙液・水に対して安定である一方、水溶性フィルム30は、高い水溶性を有し、涙液に接触することで速やかに溶解するため、該フィルムに含有される色素、検査薬または局所麻酔薬は眼表面に速やかに移行する。水溶性フィルム30は、予め水を滴下して当該水溶性フィルム30を濡らす必要がなく、涙液に接触することで速やかに溶解する。
<Ophthalmic film formulation>
As shown in FIGS. 1 and 2, the ophthalmic film preparation 10 of the present embodiment includes a water-insoluble support 20 and a water-soluble film 30 containing a pigment, a test agent or a local anesthetic and polyvinylpyrrolidone. A part of the upper surface 21 (FIG. 1), which is the surface of the water-insoluble support 20, or an end 23 (FIG. 2) perpendicular to or substantially perpendicular to the upper surface 21 of the water-insoluble support 20, and the water-soluble film 30. And is touching. In the present specification, the structure in which the water-insoluble support 20 and the water-soluble film 30 are in contact with each other as shown in FIGS. 1 and 2 may be referred to as a “two-layer structure”. The water-insoluble support 20 is stable against tears and water, while the water-soluble film 30 has high water solubility and dissolves quickly when in contact with tears. Dye, test agents or local anesthetics transferred to the ocular surface quickly. The water-soluble film 30 does not need to be preliminarily dipped in water to wet the water-soluble film 30, and quickly dissolves by contact with tears.

本実施形態の眼科用フィルム製剤10は、色素、検査薬または局所麻酔薬を投与することを目的とするため、色素、検査薬または局所麻酔薬の投与に当たっては、即溶性であることが望ましく、本実施形態に係る眼科用フィルム製剤10は、非水溶性支持体20と水溶性フィルム30との二層構造とすることができる。それにより、眼科用フィルム製剤10は、円滑にかつ短時間で色素、検査薬または局所麻酔薬の眼表面への投与が可能となる。   Since the ophthalmic film preparation 10 of the present embodiment is intended to administer a dye, a test agent or a local anesthetic, it is desirable that the ophthalmic film preparation 10 be immediately soluble upon administration of the dye, the test agent or the local anesthetic. The ophthalmic film preparation 10 according to this embodiment can have a two-layer structure of a water-insoluble support 20 and a water-soluble film 30. Thereby, the ophthalmic film preparation 10 can be smoothly and quickly administered to the ocular surface of a pigment, a test agent or a local anesthetic.

除放性が必要な眼科用フィルム製剤の場合は、薬剤層の溶解速度が遅いため、薬剤層が非水溶性支持体から離脱するまでにかなりの時間を要する。この課題は、例えば、薬剤層と非水溶性支持体との間に薬剤層よりも水溶性が高く設定された溶解分離層が形成されている三層からなる構造体とすることによって解決される。溶解分離層が涙液と接触して速やかに溶解することにより、薬剤層が眼表面に投与され、投与された薬剤層は眼表面で時間をかけて溶出することで薬効を発揮する。このような三層からなる構造体となる眼科用フィルム製剤に比べ、本実施形態の眼科用フィルム製剤10は、二層構造である場合、安価簡便な方法で製造することができ、円滑にかつ短時間で色素、検査薬または局所麻酔薬の眼表面への移行が可能となる。尚、本実施形態の眼科用フィルム製剤10は、水溶性フィルム30が色素、検査薬または局所麻酔薬を含有する薬剤層と、ポリビニルピロリドンを含有する溶解分離層とを含む態様であってもよい。該態様の場合、本実施形態の眼科用フィルム製剤10は、薬剤層と溶解分離層と非水溶性支持体20とがこの順に積層した三層構造の積層体であることが好ましい。   In the case of an ophthalmic film preparation that requires sustained release, since the dissolution rate of the drug layer is slow, it takes a considerable time until the drug layer is detached from the water-insoluble support. This problem can be solved by, for example, a three-layer structure in which a dissolution / separation layer having a higher water solubility than the drug layer is formed between the drug layer and the water-insoluble support. . When the dissolution / separation layer comes into contact with the tear fluid and dissolves quickly, the drug layer is administered to the ocular surface, and the administered drug layer exhibits a medicinal effect by elution over time on the ocular surface. Compared with such an ophthalmic film formulation that is a three-layer structure, the ophthalmic film formulation 10 of the present embodiment can be manufactured by an inexpensive and simple method when it has a two-layer structure, Transfer of the dye, test agent or local anesthetic to the ocular surface is possible in a short time. The ophthalmic film preparation 10 of the present embodiment may have a mode in which the water-soluble film 30 includes a drug layer containing a pigment, a test agent or a local anesthetic, and a dissolution / separation layer containing polyvinylpyrrolidone. . In the case of this aspect, the ophthalmic film preparation 10 of this embodiment is preferably a three-layer laminate in which a drug layer, a dissolution / separation layer, and a water-insoluble support 20 are laminated in this order.

水溶性フィルム30は、非水溶性支持体20の上面21の一部と接している構成であればよく、例えば、図1に示すように、その端部33が非水溶性支持体20の端部23と略一致するように位置してもよく、具体的には、非水溶性支持体20の上面21若しくは下面と垂直な長手方向の断面又は側面において、水溶性フィルム30の端部33と非水溶性支持体20の端部23とが、該上面21に対する1つの垂線上に位置してもよい。本明細書において、「略一致」とは、「一致」を含んでもよく、「実質的に一致」であってもよい。これにより、非水溶性支持体20によって水溶性フィルム30の片面全体が被覆され、吸湿に対する安定化を図ることが可能となり、また、色素、検査薬または局所麻酔薬を投与するために眼科用フィルム製剤10の端部を眼表面に接触させればよいので、操作が簡単である。なお、水溶性フィルム30は、その端部が非水溶性支持体20の端部と一致しない位置であってもよい。   The water-soluble film 30 may be configured so as to be in contact with a part of the upper surface 21 of the water-insoluble support 20. For example, as shown in FIG. 1, the end 33 is an end of the water-insoluble support 20. It may be positioned so as to substantially coincide with the portion 23. Specifically, in the longitudinal section or side surface perpendicular to the upper surface 21 or the lower surface of the water-insoluble support 20, the end portion 33 of the water-soluble film 30 and The end 23 of the water-insoluble support 20 may be located on one perpendicular to the upper surface 21. In this specification, “substantially match” may include “match” or may be “substantially match”. Thereby, the whole surface of the water-soluble film 30 is covered with the water-insoluble support 20, and it becomes possible to achieve stabilization against moisture absorption, and an ophthalmic film for administering a pigment, a test agent or a local anesthetic. Since the end of the preparation 10 may be brought into contact with the ocular surface, the operation is simple. In addition, the position where the edge part of the water-soluble film 30 does not correspond with the edge part of the water-insoluble support body 20 may be sufficient.

本実施形態の眼科用フィルム製剤10の形態は、図1及び図2に示すものに限定されない。例えば、図1及び図2に示す眼科用フィルム製剤10は、非水溶性支持体20の端部23と水溶性フィルム30の端部33との形状が、非水溶性支持体20の上面21若しくは下面と垂直な長手方向の断面又は側面において、直線状に形成されていたが、これに限定されない。   The form of the ophthalmic film preparation 10 of this embodiment is not limited to what is shown in FIG.1 and FIG.2. For example, in the ophthalmic film preparation 10 shown in FIGS. 1 and 2, the shape of the end portion 23 of the water-insoluble support 20 and the end portion 33 of the water-soluble film 30 is the upper surface 21 of the water-insoluble support 20 or In the longitudinal cross section or side surface perpendicular to the lower surface, it is formed in a straight line, but is not limited thereto.

図3に示す眼科用フィルム製剤10Aは、非水溶性支持体20Aと、非水溶性支持体20Aの表面の一部と接する水溶性フィルム30とから構成され、非水溶性支持体20Aの端部23Aと水溶性フィルムの端部33Aとが円弧状に形成されており、具体的には、非水溶性支持体20Aの端部23Aに接している水溶性フィルム30の非水溶性支持体20Aと反対側の端部33Aが、非水溶性支持体20の上面21若しくは下面と垂直な長手方向の断面又は側面において、円弧状に形成されていてもよい。このように構成される眼科用フィルム製剤10Aは、眼表面と接触する端部23A、33Aの形状が円弧状であるため、患者の恐怖感を低減するのに効果的であり、それにより、二層構造体である本実施形態の10Aでも、円滑にかつ短時間で色素、検査薬または局所麻酔薬の眼表面への投与が可能となる。   An ophthalmic film preparation 10A shown in FIG. 3 is composed of a water-insoluble support 20A and a water-soluble film 30 in contact with a part of the surface of the water-insoluble support 20A, and an end of the water-insoluble support 20A. 23A and the end 33A of the water-soluble film are formed in an arc shape. Specifically, the water-insoluble support 20A of the water-soluble film 30 in contact with the end 23A of the water-insoluble support 20A The opposite end 33 </ b> A may be formed in an arc shape in a longitudinal section or a side surface perpendicular to the upper surface 21 or the lower surface of the water-insoluble support 20. The ophthalmic film preparation 10A configured as described above is effective in reducing the fear of the patient because the end portions 23A and 33A in contact with the ocular surface have an arc shape. Even 10A of the present embodiment, which is a layered structure, can smoothly and quickly administer a dye, a test agent or a local anesthetic to the ocular surface.

[非水溶性支持体]
上記非水溶性支持体20は、水溶性フィルム30よりも長い寸法を有する形態であることが好ましく、水溶性フィルム30が形成されていない非水溶性支持体20の部分が、水溶性フィルム30の滅菌状態を維持しつつ眼科用フィルム製剤10を把持するための持ち手となる。他方、非水溶性支持体20の端部23は、眼表面への接触部位となる可能性もある。したがって、非水溶性支持体20のサイズは特に制限されないが、幅1〜6mm程度、長さ10〜60mm程度であることが好ましい。非水溶性支持体20は、持ち手としての操作性の観点から、幅1mm以上、長さ10mm以上あることが好ましい。また、非水溶性支持体20は、眼表面への接触部位となる可能性があるため、患者への恐怖感を与えない幅6mm以下が好ましく、使用者が眼表面の適正な位置に水溶性フィルム30を投与できるように長さ100mm以下にすることが好ましい。なお、非水溶性支持体20の幅は、長手方向に亘って同一でなくてもよく、端部23の幅と、端部23とは長手方向反対側の端部の幅が異なっていてもよい。
[Water-insoluble support]
The water-insoluble support 20 is preferably in a form having a dimension longer than that of the water-soluble film 30, and the portion of the water-insoluble support 20 where the water-soluble film 30 is not formed is the water-soluble film 30. It becomes a handle for holding the ophthalmic film preparation 10 while maintaining the sterilized state. On the other hand, the end part 23 of the water-insoluble support 20 may be a contact site to the eye surface. Therefore, the size of the water-insoluble support 20 is not particularly limited, but is preferably about 1 to 6 mm in width and about 10 to 60 mm in length. The water-insoluble support 20 is preferably 1 mm or more in width and 10 mm or more in length from the viewpoint of operability as a handle. Further, since the water-insoluble support 20 may be a contact site on the ocular surface, the width is preferably 6 mm or less so as not to give fear to the patient, and the user can make the water-soluble in an appropriate position on the ocular surface. The length is preferably 100 mm or less so that the film 30 can be administered. Note that the width of the water-insoluble support 20 may not be the same in the longitudinal direction, and the width of the end 23 may be different from the width of the end opposite to the end 23 in the longitudinal direction. Good.

非水溶性支持体20は、眼科用フィルムを眼表面に接触させた時に与える異物感を和らげるために適度な弾力性を持つことが好ましく、そのような厚みを有することが好ましい。したがって、非水溶性支持体20の平均厚みが10μm以上であることが好ましく、より好ましくは20μm以上である。他方、非水溶性支持体20の厚みが大きすぎると、非水溶性支持体20が眼表面に接触した際に、非水溶性支持体20の剛性で患者に不快感を与え得るし、非水溶性支持体20の作成コストの懸念もある。このため、非水溶性支持体20の平均厚みは、500μm以下であることが好ましく、より好ましくは300μm以下であり、さらにより好ましくは100μm以下である。   The water-insoluble support 20 preferably has an appropriate elasticity in order to relieve the feeling of foreign matter given when the ophthalmic film is brought into contact with the ocular surface, and preferably has such a thickness. Therefore, the average thickness of the water-insoluble support 20 is preferably 10 μm or more, and more preferably 20 μm or more. On the other hand, if the thickness of the water-insoluble support 20 is too large, when the water-insoluble support 20 comes into contact with the ocular surface, the rigidity of the water-insoluble support 20 can cause discomfort to the patient. There is also a concern about the production cost of the conductive support 20. For this reason, the average thickness of the water-insoluble support 20 is preferably 500 μm or less, more preferably 300 μm or less, and even more preferably 100 μm or less.

非水溶性支持体20の材質は特に限定されないが、非水溶性フィルム、非水溶性フィルムと紙製シートとの積層体などが好ましく用いられる。眼科用フィルム製剤10と眼表面との接触が極めて短時間であることから、非水溶性支持体20は通常は非水溶性フィルムのみから構成されることが好ましいが、非水溶性フィルムと紙製シートとの積層体としてもよい。非水溶性フィルムと紙製シートとを接着する手段は、特に制限されないが、例えば両面テープ、液状接着剤等の接着剤を用いて非水溶性フィルムと紙製シートとを貼り合わせてもよい。非水溶性フィルムと紙製シートとの積層体としては、具体的には、非水溶性フィルムと接着剤層と紙製シートとの積層体であってよく、非水溶性フィルムと接着剤層と紙製シートとがこの順に積層した積層体が好ましく、その場合、水溶性フィルム30は非水溶性フィルム上に積層されることが好ましい。   Although the material of the water-insoluble support 20 is not particularly limited, a water-insoluble film, a laminate of a water-insoluble film and a paper sheet, or the like is preferably used. Since the contact between the ophthalmic film preparation 10 and the ocular surface is extremely short, the water-insoluble support 20 is usually preferably composed only of a water-insoluble film. It is good also as a laminated body with a sheet | seat. The means for adhering the water-insoluble film and the paper sheet is not particularly limited. For example, the water-insoluble film and the paper sheet may be bonded using an adhesive such as a double-sided tape or a liquid adhesive. As a laminate of a water-insoluble film and a paper sheet, specifically, a laminate of a water-insoluble film, an adhesive layer and a paper sheet may be used. A laminate in which paper sheets are laminated in this order is preferable. In that case, the water-soluble film 30 is preferably laminated on a water-insoluble film.

非水溶性フィルムとしては、水に不溶性(少なくとも水溶性フィルム30よりも水不溶性であることは必須)のフィルムであれば制限されないが、例えばポリエチレンテレフタラート(PET)、ポリプロピレン(PP)、ポリエチレンナフタレート(PEN)、ポリエステル、ポリカーボネート、及びこれらの組み合わせからなる高分子フィルムが挙げられる。非水溶性フィルムの色は特に制限されないが、水溶性フィルム30の色と異なることが好ましい。例えば、検査薬としてフルオレセインのナトリウム塩を用いる場合には、非水溶性フィルムの色はフルオレセインのナトリウム塩の黄色〜橙色と区別できることが好ましく、例えば白色、透明などが挙げられる。   The water-insoluble film is not limited as long as it is insoluble in water (at least it is essential to be water-insoluble than the water-soluble film 30). For example, polyethylene terephthalate (PET), polypropylene (PP), polyethylene Examples thereof include polymer films made of phthalate (PEN), polyester, polycarbonate, and combinations thereof. The color of the water-insoluble film is not particularly limited, but is preferably different from the color of the water-soluble film 30. For example, when the sodium salt of fluorescein is used as a test agent, the color of the water-insoluble film is preferably distinguishable from the yellow to orange color of the sodium salt of fluorescein, and examples thereof include white and transparent.

[水溶性フィルム]
上記水溶性フィルム30は、眼表面の涙液に接触して速やかに溶解し(少なくとも前述の非水溶性フィルムよりも速やかに溶解することは必須)、色素、検査薬または局所麻酔薬を速やかに眼表面に移行させる役割を有する。水溶性フィルムの材質は、ポリビニルピロリドン(以下、PVPと表記することがある)であれば特に制限されないが、K値の異なるポリビニルピロリドンを組み合わせて用いることがより好ましい。
[Water-soluble film]
The water-soluble film 30 comes into contact with the tears on the surface of the eye and dissolves quickly (at least it is necessary to dissolve faster than the above-mentioned water-insoluble film), and the pigment, the test agent or the local anesthetic is promptly dissolved. It has a role to transfer to the ocular surface. The material of the water-soluble film is not particularly limited as long as it is polyvinyl pyrrolidone (hereinafter sometimes referred to as PVP), but it is more preferable to use a combination of polyvinyl pyrrolidones having different K values.

上記水溶性フィルム30の面積は、特に限定されないが、3〜100mmが好ましく、より好ましくは10〜30mmである。ここで、水溶性フィルム30の面積は、非水溶性支持体20との接触面またはその反対面の面積である。上記水溶性フィルム30の面積が3mm以上であれば、必要な量の色素、検査薬、局所麻酔薬を存置させることが可能であり、100mm以下であれば、眼表面に接触させる箇所の面積も大きくなく、患者の恐怖感も低減される。 Although the area of the said water-soluble film 30 is not specifically limited, 3-100 mm < 2 > is preferable, More preferably, it is 10-30 mm < 2 >. Here, the area of the water-soluble film 30 is the area of the contact surface with the water-insoluble support 20 or the opposite surface. If the area of the water-soluble film 30 is 3 mm 2 or more, it is possible to leave a necessary amount of a dye, a test agent, or a local anesthetic, and if the area is 100 mm 2 or less, The area is not large, and the fear of the patient is reduced.

水溶性フィルム30の乾燥後の平均厚みは、特に限定されないが1〜30μmが好ましく、より好ましくは5〜15μmである。上記水溶性フィルム30の厚みを小さくすれば、必要な量の色素、検査薬、局所麻酔薬を存置するために水溶性フィルム30の面積が大きくなるが、水溶性フィルム30の乾燥後の平均厚みを1μm以上とすることにより、必要な量の色素、検査薬、局所麻酔薬を存置しつつ、面積を過大にせずに速溶効果を発揮できる。また、水溶性フィルム30の平均厚みを30μm以下とすることにより、涙液接触開始から溶解終了までの時間を短縮して、患者への負担を減らすことができる。   Although the average thickness after drying of the water-soluble film 30 is not specifically limited, 1-30 micrometers is preferable, More preferably, it is 5-15 micrometers. If the thickness of the water-soluble film 30 is reduced, the area of the water-soluble film 30 is increased in order to retain a necessary amount of pigment, test agent, and local anesthetic, but the average thickness after drying of the water-soluble film 30 is increased. By setting the thickness to 1 μm or more, it is possible to exhibit a fast-dissolving effect without increasing the area while keeping a necessary amount of a dye, a test agent, and a local anesthetic. Moreover, by setting the average thickness of the water-soluble film 30 to 30 μm or less, the time from the start of tear contact to the end of dissolution can be shortened, and the burden on the patient can be reduced.

また、水溶性フィルム30は、非水溶性支持体20から平面方向に1mmを超えて突出させないことが好ましい。突出部分は、その両面が雰囲気に曝され吸湿安定性の点で懸念されるが、非水溶性用支持体によって片面が被覆されることで、吸湿に対する安定化を図ることが可能である。   The water-soluble film 30 is preferably not protruded from the water-insoluble support 20 by exceeding 1 mm in the plane direction. Although both sides of the protruding portion are exposed to the atmosphere and there is a concern in terms of moisture absorption stability, it is possible to stabilize moisture absorption by covering one surface with a water-insoluble support.

上述した特性を満たす上記水溶性フィルム30は、ポリビニルピロリドンと、色素、検査薬または局所麻酔薬とを含有する。水溶性フィルム30には、水溶性を高めるためにマンニトールなどの糖アルコールやオリゴマー、テロマーなどの分子量が大きくない水溶性高分子を添加したり、気泡を導入したりすることもできる。必要に応じて2種以上の水溶性ポリマーを配合することもできる。   The water-soluble film 30 that satisfies the above-described characteristics contains polyvinylpyrrolidone and a dye, a test agent, or a local anesthetic. In order to enhance water solubility, the water-soluble film 30 can be added with a water-soluble polymer having a low molecular weight such as sugar alcohol such as mannitol, oligomers, and telomers, or air bubbles can be introduced. If necessary, two or more water-soluble polymers can be blended.

また、水溶性フィルム30には、必要に応じて可塑剤や乳化剤を配合することができる。可塑剤としては、濃グリセリン、マクロゴール、乳化剤としては、ポリソルベート80などが好適に用いられる。水溶性フィルム30に可塑剤を含有させることによって、水溶性フィルム30の柔軟性が増し、ひび割れや非水溶性支持体からの剥離を確実に防止することができる。   Moreover, a plasticizer and an emulsifier can be mix | blended with the water-soluble film 30 as needed. As the plasticizer, concentrated glycerin, macrogol, and as the emulsifier, polysorbate 80 or the like is preferably used. By including a plasticizer in the water-soluble film 30, the flexibility of the water-soluble film 30 is increased, and cracks and peeling from the water-insoluble support can be reliably prevented.

[ポリビニルピロリドン]
ポリビニルピロリドンは、水溶性ポリマーの中でも水への溶解性に優れる。このため、涙液に接触して速やかに溶解する必要がある水溶性フィルム30に好適に用いられる。
[Polyvinylpyrrolidone]
Polyvinyl pyrrolidone is excellent in solubility in water among water-soluble polymers. For this reason, it uses suitably for the water-soluble film 30 which needs to contact | disconnect tear fluid and to melt | dissolve rapidly.

本実施形態で使用されるポリビニルピロリドンのK値は25〜90のものが好ましく、例えばポリビニルピロリドンK−30、ポリビニルピロリドンK−85、ポリビニルピロリドンK−90などが挙げられる。なお、ポリビニルピロリドンのK値は、分子量と相関する粘性特性値で、毛細管粘度計により測定される相対粘度値(25℃)を下記のFikentscherの式(1)に適用して計算される数値である。

Figure 2017043607
式(1)中、ηrelは、ポリビニルピロリドン水溶液の水に対する相対粘度、cは、ポリビニルピロリドン水溶液中のポリビニルピロリドン濃度(%)である。 The K value of polyvinylpyrrolidone used in the present embodiment is preferably 25 to 90, and examples thereof include polyvinylpyrrolidone K-30, polyvinylpyrrolidone K-85, and polyvinylpyrrolidone K-90. The K value of polyvinylpyrrolidone is a viscosity characteristic value that correlates with the molecular weight, and is a numerical value calculated by applying a relative viscosity value (25 ° C.) measured by a capillary viscometer to the following Fikenscher equation (1). is there.
Figure 2017043607
In formula (1), ηrel is the relative viscosity of the aqueous polyvinylpyrrolidone solution to water, and c is the polyvinylpyrrolidone concentration (%) in the aqueous polyvinylpyrrolidone solution.

ポリビニルピロリドンK−30は、水への溶解性は良好だが、吸湿性が高く物理的にやや不安定であるため保存安定性にやや劣るのに対し、ポリビニルピロリドンK−90は、水への溶解性はやや劣るが、吸湿性が低く物理的に安定であるため保存安定性に優れている。したがって、例えばポリビニルピロリドンK−30とポリビニルピロリドンK−90を混合すれば、眼表面への染色性及び保存安定性の良好な眼科用フィルム製剤10の水溶性フィルム30が得られる。   Polyvinylpyrrolidone K-30 has good solubility in water but is slightly inferior in storage stability because it is highly hygroscopic and slightly unstable, whereas polyvinylpyrrolidone K-90 is soluble in water. Although the property is slightly inferior, it is excellent in storage stability because it has low hygroscopicity and is physically stable. Therefore, for example, when polyvinyl pyrrolidone K-30 and polyvinyl pyrrolidone K-90 are mixed, the water-soluble film 30 of the ophthalmic film preparation 10 having good dyeability and storage stability on the ocular surface can be obtained.

K値の異なるポリビニルピロリドンの混合割合を変化させることにより、水への溶解性にも、保存安定性にも優れた水溶性フィルム30を得ることが可能となる。例えば、ポリビニルピロリドンK−30とポリビニルピロリドンK−90とを混合する場合には、PVP K30に対して、PVP K90を10質量%〜50%質量%混合させるのが好ましく、より好ましくは15質量%〜45質量%である。   By changing the mixing ratio of polyvinyl pyrrolidone having different K values, it is possible to obtain a water-soluble film 30 having excellent solubility in water and storage stability. For example, when mixing polyvinyl pyrrolidone K-30 and polyvinyl pyrrolidone K-90, it is preferable to mix 10 mass%-50 mass% of PVP K90 with respect to PVP K30, More preferably, it is 15 mass%. It is -45 mass%.

[色素]
色素としては、例えばローズベンガル、リサミングリーン、インドシアニングリーンなどの眼用色素が挙げられる。色素は眼表面を染色できる濃度であれば問題ないので、水溶性フィルム30中の色素の含有量は、特に制限されないが、好ましくは1〜60質量%である。
[Dye]
Examples of the dye include ophthalmic dyes such as rose bengal, lissamine green, and indocyanine green. Since there is no problem as long as the dye has a concentration capable of staining the ocular surface, the content of the dye in the water-soluble film 30 is not particularly limited, but is preferably 1 to 60% by mass.

[検査薬]
検査薬としては、例えばフルオレセインまたはその塩、トロピカミド、フェニレフリンなどの眼溶検査薬が挙げられる。フルオレセイン二ナトリウム塩(以下、フルオレセインナトリウムと表記する)は、眼科における検査用試薬として広く用いられ、角結膜障害の診断、例えばドライアイ、角結膜の擦過傷、潰瘍、角膜ヘルペスなどの診断に有効である。水溶性フィルム30中の検査薬の含有量は、特に制限されないが、例えばフルオレセインナトリウムの場合には、医療現場での迅速な染色を前提にすると5〜70質量%が好ましく、より好ましくは40〜60質量%である。
[Testing agent]
Examples of the test drug include ophthalmic test drugs such as fluorescein or a salt thereof, tropicamide, phenylephrine and the like. Fluorescein disodium salt (hereinafter referred to as fluorescein sodium) is widely used as a diagnostic reagent in ophthalmology, and is effective in diagnosing keratoconjunctival disorders, such as dry eye, keratoconjunctival scratches, ulcers, and corneal herpes. is there. The content of the test agent in the water-soluble film 30 is not particularly limited. However, for example, in the case of sodium fluorescein, it is preferably 5 to 70% by mass, more preferably 40 to 40% on the premise of quick dyeing at a medical site. 60% by mass.

[局所麻酔薬]
局所麻酔薬としては、例えば、オキシブプロカインまたはその塩が挙げられる。オキシブプロカインの塩としては、塩酸オキシブプロカイン(ベノキシール)などが挙げられる。他に、塩酸ジブカイン、塩酸プロカイン、塩酸リドカインなどが挙げられる。これら局所麻酔薬の含有量は、特に制限されないが、薬効を得るうえで、1〜50質量%が好ましく、より好ましくは2〜20質量%である。
[Local anesthetic]
Examples of the local anesthetic include oxybuprocaine or a salt thereof. Examples of the salt of oxybuprocaine include oxybuprocaine hydrochloride (Benoxyal). In addition, dibucaine hydrochloride, procaine hydrochloride, lidocaine hydrochloride and the like can be mentioned. Although content in particular of these local anesthetics is not restrict | limited, In order to obtain a medicinal effect, 1-50 mass% is preferable, More preferably, it is 2-20 mass%.

水溶性フィルム30は、色素、検査薬、局所麻酔薬から選ばれる少なくとも1種を含有し、色素、検査薬、局所麻酔薬のすべてを含有することもできる。色素、検査薬及び局所麻酔薬の合計含有量は、水溶性フィルム30中、1〜70質量%であることが好ましい。色素、検査薬及び局所麻酔薬の合計含有量を1質量%以上とすることにより、色素、検査薬局所麻酔薬の薬効等を期待することができる。色素、検査薬及び局所麻酔薬の含有量が多すぎると水溶性フィルムを構成する水溶性ポリマーの量が足りず、涙液に対する速溶性が足りなくなりやすい。よって、色素、検査薬及び局所麻酔薬の含有量を70質量%以下とすることにより、十分な速溶性を確保することができる。   The water-soluble film 30 contains at least one selected from a dye, a test agent, and a local anesthetic, and can also contain all of a dye, a test agent, and a local anesthetic. The total content of the dye, the test agent and the local anesthetic is preferably 1 to 70% by mass in the water-soluble film 30. By setting the total content of the pigment, the test agent and the local anesthetic to 1% by mass or more, the efficacy of the pigment, the test agent and the local anesthetic can be expected. If the content of the dye, the test agent and the local anesthetic is too large, the amount of the water-soluble polymer constituting the water-soluble film is insufficient, and the rapid solubility in tear fluid tends to be insufficient. Therefore, sufficient fast solubility can be ensured by making content of a pigment | dye, a test | inspection agent, and a local anesthetic into 70 mass% or less.

<眼科用フィルム製剤の製造方法>
本実施形態の眼科用フィルム製剤は、例えば、色素、検査薬または局所麻酔薬と、ポリビニルピロリドンとを含有する水溶性フィルム塗工液を非水溶性支持体上に塗布する工程を含む方法により、製造することができる。
水溶性フィルム塗工液は、その固形分が例えば1〜60質量%、好ましくは5〜50質量%、より好ましくは10〜40質量%である液体であってよい。水溶性フィルム塗工液は、例えば、少なくともポリビニルピロリドンを溶解し得る溶剤に溶解することにより、調製することができる。該溶剤としては特に限定されず、例えば、水、エタノール等のアルコールまたは水とアルコールの混合溶剤が挙げられ、特に水とエタノールの混合溶剤が好ましい。
<Method for producing ophthalmic film preparation>
The ophthalmic film preparation of the present embodiment includes, for example, a method including a step of applying a water-soluble film coating solution containing a pigment, a test agent or a local anesthetic and polyvinylpyrrolidone on a water-insoluble support. Can be manufactured.
The water-soluble film coating liquid may be a liquid having a solid content of, for example, 1 to 60% by mass, preferably 5 to 50% by mass, and more preferably 10 to 40% by mass. The water-soluble film coating solution can be prepared, for example, by dissolving in at least a solvent capable of dissolving polyvinylpyrrolidone. The solvent is not particularly limited, and examples thereof include water, alcohol such as ethanol, or a mixed solvent of water and alcohol, and a mixed solvent of water and ethanol is particularly preferable.

水溶性フィルム塗工液を非水溶性支持体上に塗布する方法としては、特に限定されず、例えば、ディップコーター、ロールコーター、カーテンコーター、スプレーコーター等を用いて塗布する方法等が挙げられる。水溶性フィルム塗工液を非水溶性支持体上に塗布して得られる塗布膜の膜厚は、乾燥後の水溶性フィルムが所望の平均厚みとなるように適宜調整すればよく、例えば、該乾燥後の平均厚みを1μmとする場合、1〜200μmとすることができ、乾燥後の平均厚みを5μmとする場合、5〜200μmとすることができ、乾燥後の平均厚みを15μmとする場合、15〜450μmとすることができ、乾燥後の平均厚みを30μmとする場合、30〜600μmとすることができる。   The method for applying the water-soluble film coating solution on the water-insoluble support is not particularly limited, and examples thereof include a method using a dip coater, a roll coater, a curtain coater, a spray coater and the like. The film thickness of the coating film obtained by applying the water-soluble film coating solution on the water-insoluble support may be appropriately adjusted so that the water-soluble film after drying has a desired average thickness. When the average thickness after drying is 1 μm, it can be 1 to 200 μm, when the average thickness after drying is 5 μm, it can be 5 to 200 μm, and the average thickness after drying is 15 μm When the average thickness after drying is 30 μm, the thickness can be 30 to 600 μm.

水溶性フィルム塗工液を非水溶性支持体上に塗布した後、温風、オーブン、ホットプレート等の加熱装置上に載置することによる加熱、放置等の方法により乾燥して、不要な溶剤を除去することが好ましい。その後、特に水溶性フィルムが眼科用フィルム製剤1つ当りの望ましい面積となるように適切な大きさに切断すること等により、眼科用フィルム製剤を調製することができる。非水溶性支持体が非水溶性フィルムと紙製シートとの積層体である場合、上記非水溶性支持体として該積層体を用いてもよいし、上記水溶性フィルム塗工液の塗布を非水溶性フィルム上に行い、上記切断後に両面テープ等の接着剤を用いて非水溶性フィルムと紙製シートとを貼り合わせて作製してもよい。   After applying the water-soluble film coating solution on the water-insoluble support, it is dried by a method such as heating, leaving it on a heating device such as hot air, oven, hot plate, etc. Is preferably removed. Thereafter, the ophthalmic film preparation can be prepared by cutting into an appropriate size so that the water-soluble film has a desired area per ophthalmic film preparation. When the water-insoluble support is a laminate of a water-insoluble film and a paper sheet, the laminate may be used as the water-insoluble support, or the water-soluble film coating solution is not applied. It may be produced on a water-soluble film, and after the cutting, a water-insoluble film and a paper sheet may be bonded together using an adhesive such as a double-sided tape.

<眼科用フィルム製剤の使用方法>
次に、この眼科用フィルム製剤10の使用方法について説明する。例えば、角膜、眼瞼結膜または結膜襄などの前眼部に投与されるが、水溶性フィルム30を眼表面に投与する場合を例に挙げて説明する。使用者は、眼科用フィルム製剤10の非水溶性支持体20の端部23とは反対側の端部近傍を指で摘み、水溶性フィルム30を投与部位に近づける。本実施形態では、一方の手の指で下眼瞼を引き下げて結膜を露出させるとともに、他方の手の指で非水溶性支持体20の端部23とは反対側の端部近傍部位を摘んで、非水溶性支持体20の端部23及び水溶性フィルム30の端部33を眼表面に近づけて露出した結膜に接触させる。この際、結膜に接触した水溶性フィルム30は、涙液で速やかに溶解し、色素、検査薬または局所麻酔薬を眼表面に確実に移行させることができる。
<Usage method of ophthalmic film preparation>
Next, the usage method of this ophthalmic film formulation 10 is demonstrated. For example, although it administers to an anterior eye part, such as a cornea, a lid conjunctiva, or a conjunctival fistula, the case where the water-soluble film 30 is administered to an ocular surface is mentioned as an example, and is demonstrated. The user picks the vicinity of the end opposite to the end 23 of the water-insoluble support 20 of the ophthalmic film preparation 10 with a finger, and brings the water-soluble film 30 close to the administration site. In the present embodiment, the lower eyelid is pulled down with the finger of one hand to expose the conjunctiva, and the region near the end opposite to the end 23 of the water-insoluble support 20 is grasped with the finger of the other hand. The end 23 of the water-insoluble support 20 and the end 33 of the water-soluble film 30 are brought into contact with the exposed conjunctiva close to the eye surface. At this time, the water-soluble film 30 in contact with the conjunctiva can be quickly dissolved with tears, and the dye, the test agent or the local anesthetic can be reliably transferred to the ocular surface.

上述した眼科用フィルム製剤10、10Aは、外眼部、前眼部及び涙器の疾患の治療前の検査、及び/または治療後に治療効果を確認するための検査に用いる検査薬として好適に用いることができる。例えば、涙液層破壊時間検査、眼圧測定、ハードコンタクトレンズ装着検査などが挙げられる。従来、点眼投与が一般的であった手法に対して、より簡便に色素、検査薬または局所麻酔薬を眼表面に投与することができる。特に上を向いたままの姿勢で点眼をすることができない患者に有用であり、また、重力による点眼が不可能となる宇宙空間などの無重力空間でも色素、検査薬または局所麻酔薬の眼への適正投与が可能となる。   The above-described ophthalmic film preparations 10 and 10A are preferably used as a test agent used for an examination before treatment of diseases of the external eye part, anterior eye part and lacrimal organs and / or examination for confirming the therapeutic effect after treatment. be able to. For example, tear film destruction time test, intraocular pressure measurement, hard contact lens wearing test, and the like can be mentioned. Conventionally, a dye, a test agent, or a local anesthetic can be more easily administered to the ocular surface than a method in which ophthalmic administration has been common. It is especially useful for patients who cannot be instilled with their postures facing upwards. Also, pigments, test agents, or local anesthetics are applied to the eyes even in a non-gravity space such as outer space where instillation by gravity is impossible. Proper administration is possible.

涙液層破壊時間検査は、目の表面を覆っている涙液層が破壊し始める時間を調べる検査である。フルオレセイン等の検査薬が投与され、細隙灯顕微鏡で青色光を用いて目の表面を観察すると、涙に混ざって緑色に見える。まばたきを止めて、真っすぐ正面を見ていると、しだいに涙液層が破壊して色調に変化が生じる。この時間をBUT(Tear Break Up Time)と呼び、一般的には、10秒以上ならば正常、5秒以下ならばドライアイと診断される。   The tear film breakage time test is a test for examining the time when the tear film covering the surface of the eye starts to break. When a test drug such as fluorescein is administered and the surface of the eye is observed with blue light with a slit lamp microscope, it appears green when mixed with tears. When you stop blinking and look straight ahead, the tear film gradually breaks and changes in color. This time is called BUT (Tear Break Up Time). Generally, if it is 10 seconds or more, it is normal, and if it is less than 2 seconds, it is diagnosed as dry eye.

また、上述した眼科用フィルム製剤10、10Aは、外眼部、前眼部及び涙器の疾患の治療剤または眼圧関連疾患治療剤と組み合わせて使用することができる。例えば、外眼部、前眼部及び涙器の疾患治療剤として用いられる人工涙液、ジクアホソル点眼液、ヒアルロン酸ナトリウム点眼液、レバミピド点眼液などの点眼液と組み合わせて使用することができる。眼圧関連疾患治療剤として用いられるラタノプロスト点眼液、タフルプロスト点眼液、チモロール点眼液などの点眼液と組み合わせて使用することもできる。眼圧関連疾患治療剤は、例えば、緑内障治療剤、高眼圧症治療剤等の眼圧の異常を来す場合がある疾患の治療剤である。   Moreover, the above-described ophthalmic film preparations 10, 10A can be used in combination with a therapeutic agent for diseases of the external eye part, anterior eye part and lacrimal organs or a therapeutic agent for intraocular pressure-related diseases. For example, it can be used in combination with ophthalmic solutions such as artificial tears, diquafosol ophthalmic solution, sodium hyaluronate ophthalmic solution, rebamipide ophthalmic solution used as a therapeutic agent for diseases of the external eye part, anterior eye part and lacrimal organs. It can also be used in combination with ophthalmic solutions such as latanoprost ophthalmic solution, tafluprost ophthalmic solution, timolol ophthalmic solution used as a therapeutic agent for intraocular pressure-related diseases. The therapeutic agent for intraocular pressure-related diseases is a therapeutic agent for diseases that may cause abnormal intraocular pressure, such as a therapeutic agent for glaucoma and a therapeutic agent for ocular hypertension.

本発明は、上述した眼科用フィルム製剤を用いた外眼部、前眼部もしくは涙器の疾患の検査、眼圧測定、ハードコンタクトレンズ装着検査または涙液層破壊時間検査と組み合わせて使用される外眼部、前眼部もしくは涙器の疾患治療剤または眼圧関連疾患治療剤も包含する。外眼部、前眼部もしくは涙器の疾患治療剤または眼圧関連疾患治療剤の具体例は、前述の通りである。   The present invention is used in combination with the above-described ophthalmic film preparation for examination of diseases of the external eye part, anterior eye part or lacrimal organ, intraocular pressure measurement, hard contact lens wearing examination or tear film destruction time examination. It also includes a therapeutic agent for diseases of the external eye, anterior segment or lacrimal organs or a therapeutic agent for intraocular pressure-related diseases. Specific examples of the external eye part, anterior eye part or lacrimal organ disease therapeutic agent or intraocular pressure-related disease therapeutic agent are as described above.
