It is preferably sealed and packaged using various known sealing means. This ensures that edaravone is more stably stored over time. Specific examples include an alumina vapor-deposited film, an aluminum vapor-deposited film, a laminate film having an aluminum foil layer, and a silica vapor-deposited film. With such a configuration, it is possible to effectively prevent oxygen from entering from the outside. In addition, by giving gas permeability to a plastic container, it is stable even if the packaging bag is omitted by performing sufficient oxygen control when filling the container with an aqueous preparation containing edaravone and during sterilization. It can be stored reliably.
本発明は、エダラボンを含有する水性製剤を、容器の少なくとも一部が環状ポリオレフィン樹脂で構成されたプラスチック製容器に収納したエダラボン含有水性製剤であるので、既にガラスアンプルに充填されて製造されているエダラボン製剤と同じ濃度の水性製剤はもとより、エダラボン濃度の薄いプレミックスタイプの水性製剤においてもエダラボンの実質的な変質や含有量の低下のない安定性に優れたエダラボン水性製剤が提供できる。 Since the present invention is an edaravone-containing aqueous preparation in which an aqueous preparation containing edaravone is housed in a plastic container in which at least a part of the container is composed of a cyclic polyolefin resin, it is already manufactured by being filled in a glass ampule. In addition to aqueous preparations having the same concentration as that of edaravone preparations, edaravone aqueous preparations having excellent stability without substantial alteration or content reduction of edaravone can be provided even in a premix type aqueous preparation having a low edaravone concentration.

Outer layer: PP resin (20 μm) / Intermediate layer: ZEONEX (30 μm) / Inner layer: PP resin (200 μm)
Reference Example 1 20 mL of edaravone-containing aqueous preparation was filled in an injection container having the following sheet configuration prepared by vapor-depositing the above parylene C on the inner surface of a 20-mL capacity PP bag having a sheet thickness of 350 μm. Was subjected to high-pressure steam sterilization to produce a soft bag preparation.
PP resin / Parylene C, thickness 350 / 3-5 (μm)
(Reference Example 2) 20 mL of edaravone-containing aqueous preparation was filled in an injection container having the following sheet structure prepared by vapor-depositing the above parylene C on the inner surface of a 20 mL capacity PE bag having a sheet thickness of 260 μm. Was subjected to high-pressure steam sterilization to produce a soft bag preparation.
PE resin / Parylene C, thickness 260/3 to 5 (μm)
(Test Example 2) After sealing the bags obtained in Examples 9 and 10 and Reference Examples 1 and 2 with an oxygen scavenger (trade name Ageless, manufactured by Mitsubishi Gas Chemical Co., Ltd.) in a bag made of an aluminum vapor deposited film. When it was stored at 60 ° C. for 21 days and the residual ratio relative to the content of edaravone at the start of the test was determined, it was as shown in Table 3 below. Moreover, the results of pH were as shown in Table 4.
(実施例11) エダラボン・プレミックス製剤を50mL容量の以下の材質からなる注射剤容器に50mL充填し、常法により高圧蒸気滅菌をして、プレフィルドシリンジを製した。
ガスケット:スチレン−ブタジエンゴム(SBR、興国インテック(株))製ガスケット本体をポリテトラフルオロエチレン(PTFE)フィルムにて先端面から外側面にわたって被覆
外筒:シクロオレフィンポリマー(ゼオネックス)製
(実施例12) エダラボン・プレミックス製剤を50mL容量の以下のシート構成の注射剤容器に50mL充填し、常法により高圧蒸気滅菌をして、軟質バッグ製剤を製した。
外層:PP系樹脂(200μm)/中間層:ZEONEX(30μm)/内層:PP系樹脂(20μm)
(試験例3) 実施例11〜12で得られた注射剤容器をアルミ蒸着フィルムからなる袋に脱酸素剤(商品名エージレス、三菱ガス化学(株)製)をいれて密封後、60℃条件下で21日間保存し、試験開始時のエダラボンの含有量に対する残存率を求めたところ、下記の表5に示すとおりであった。また、pHの結果は、表6に示すとおりであった。(Example 11) An edaravone premix preparation was filled with 50 mL of a 50 mL capacity injection container made of the following materials, and sterilized by high-pressure steam by a conventional method to prepare a prefilled syringe.
Gasket: Styrene-butadiene rubber (SBR, Kogoku Intec Co., Ltd.) gasket main body coated with polytetrafluoroethylene (PTFE) film from the tip surface to the outer surface Outer cylinder: Cycloolefin polymer (Zeonex) (Example 12) ) 50 mL of the edaravone premix preparation was filled into a 50 mL capacity injection container of the following sheet constitution, and autoclaved by a conventional method to produce a soft bag preparation.
Outer layer: PP resin (200 μm) / Intermediate layer: ZEONEX (30 μm) / Inner layer: PP resin (20 μm)
(Test Example 3) The injection container obtained in Examples 11 to 12 was sealed with an oxygen scavenger (trade name Ageless, manufactured by Mitsubishi Gas Chemical Co., Ltd.) in a bag made of an aluminum vapor-deposited film, and then sealed at 60 ° C. The sample was stored for 21 days, and the residual ratio relative to the content of edaravone at the start of the test was determined. The result was as shown in Table 5 below. The results of pH were as shown in Table 6.
以上の各試験例の結果から、エダラボンを含有する水性製剤を収納する容器の少なくとも一部が、環状ポリオレフィン樹脂で構成されていれば、60℃条件下で21日間保存した時、製剤の残存率は、90%以上を保つことがわかった。
表1の結果から、ガスケットに、ポリテトラフルオロエチレンフィルムにて被覆したスチレン−ブタジエンゴム、もしくは、パリレンCにて被覆したスチレン系エラストマー、もしくは、パリレンCにて被覆したブチルゴムを用いた容器では、ガラスアンプルと同等の安定性を有することがわかった。
表3の結果から、ゼオネックス層が容器の接液部になくても、製剤の安定性が保てることがわかった。但し、接液部の層の厚みが薄いほど、安定性は増すことも明らかとなった。
表5の結果から、エダラボンの濃度が薄いプレミックスタイプの水性製剤においても、安定性が保てることが明らかとなった。
表2、4、6の結果からは、21日間保存後のpHの変化は、ほとんどなかったことが確認された。From the results of the above test examples, if at least a part of the container containing the aqueous preparation containing edaravone is composed of a cyclic polyolefin resin, the residual rate of the preparation when stored for 21 days at 60 ° C. Was found to remain above 90%.
From the results of Table 1, in a container using a gasket, a styrene-butadiene rubber coated with a polytetrafluoroethylene film, a styrene elastomer coated with Parylene C, or a butyl rubber coated with Parylene C, It was found to have the same stability as a glass ampoule.
From the results of Table 3, it was found that the stability of the preparation can be maintained even when the ZEONEX layer is not in the liquid contact part of the container. However, it has also been found that the stability increases as the thickness of the layer in contact with the liquid decreases.
From the results of Table 5, it was revealed that the stability can be maintained even in a premix type aqueous preparation having a low concentration of edaravone.
From the results of Tables 2, 4, and 6, it was confirmed that there was almost no change in pH after storage for 21 days.
