Description

本発明は、ロキソプロフェンナトリウムの非水系基剤中での薬物溶解性を改善し、さらに高い保存安定性と優れた粘着性を有することを目的としたロキソプロフェンナトリウム含有テープ剤に関する。さらに詳しくは、本発明は、特定のヒドロキシカルボン酸、特定の脂肪酸およびテルペン樹脂を使用することにより、有効成分であるロキソプロフェンナトリウムの溶解性を改善し、保存安定性が高く、かつ、粘着性に優れたロキソプロフェンナトリウム含有テープ剤に関するものである。   The present invention relates to a loxoprofen sodium-containing tape agent for the purpose of improving the drug solubility of loxoprofen sodium in a non-aqueous base and having higher storage stability and excellent adhesiveness. More specifically, the present invention improves the solubility of loxoprofen sodium, which is an active ingredient, by using a specific hydroxycarboxylic acid, a specific fatty acid and a terpene resin, has high storage stability, and is tacky. The present invention relates to an excellent loxoprofen sodium-containing tape.

非ステロイド性抗炎症薬(Non−Steroidal Anti−Inflammatory Drugs、NSAIDs)は、慢性関節リウマチ、変形性関節症、腰痛症、頸肩腕症候群、肩関節周囲炎、歯痛、急性上気道炎、手術後・外傷後・抜歯後などの消炎・鎮痛・解熱に有効なものとして幅広く使用されている。しかし、NSAIDsは経口投与すると、副作用としての胃粘膜刺激、小腸での潰瘍形成などの消化管障害が生じることがある。このため、副作用を軽減する手段として、皮膚を介した投与であるパップ剤やテープ剤などの外用貼付剤が開発されている。   Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) are rheumatoid arthritis, osteoarthritis, low back pain, cervical shoulder arm syndrome, periarthritis, tooth pain, acute upper respiratory tract inflammation, postoperative Widely used as an effective anti-inflammatory, analgesic and antipyretic after trauma and tooth extraction. However, when NSAIDs are administered orally, gastrointestinal disorders such as gastric mucosal irritation and ulceration in the small intestine may occur as side effects. For this reason, external patches such as cataplasms and tapes that are administered through the skin have been developed as means for reducing side effects.

ロキソプロフェンナトリウムは、優れた抗炎症作用を有する水溶性のNSAIDsである。
ロキソプロフェンナトリウムのような水溶性のNSAIDsは、テープ剤に代表されるような非水系基剤中で均一に溶解保持させることが極めて難しく、薬効を得ることが難しい。このため、非水系基剤に薬物を均一に溶解保持させる方法として、ロキソプロフェンナトリウムの遊離状態のものよりも強酸性の酸を配合する方法が提案されている。例えば、ロキソプロフェンナトリウムを含有する外用貼付剤として、アルカリ金属の塩形態を有する非ステロイド性抗炎症薬とその遊離状態のものよりも強酸性の無機酸を非水系基剤に配合する外用貼付剤が知られている(特許文献1)。しかし、無機酸単独では薬物溶解性が十分には改善されず、非水系基剤中での薬物均一性が十分ではないため、満足なものとは言えない。また、有機酸を配合したものは、ロキソプロフェンナトリウムとの反応性が高く、保存安定性の点で、無機酸を配合したものに劣る。このため、有機酸を配合した場合、ピロリドン化合物との併用(特許文献2)、溶解剤との併用(特許文献3)により、ロキソプロフェンナトリウムの溶解性を改善し、かつ、保存安定性を確保した外用貼付剤を調製する方法が公開されている。しかし、これらの方法では、テープ剤として必要な粘着力に課題があり、目的を達成した製剤の開発には至っていない。
そこで、薬物溶解性が高く、保存安定性が高く、かつ、粘着性に優れたロキソプロフェンナトリウム含有テープ剤の開発が望まれていた。
Loxoprofen sodium is a water-soluble NSAIDs with excellent anti-inflammatory effects.
Water-soluble NSAIDs such as loxoprofen sodium are extremely difficult to uniformly dissolve and hold in non-aqueous bases such as tapes, and it is difficult to obtain medicinal effects. For this reason, as a method for uniformly dissolving and maintaining the drug in the non-aqueous base, a method of blending a more acidic acid than that in the free state of loxoprofen sodium has been proposed. For example, as an external patch containing loxoprofen sodium, an external patch containing a non-steroidal anti-inflammatory drug having an alkali metal salt form and an inorganic acid that is more acidic than its free form in a non-aqueous base is available. Known (Patent Document 1). However, the inorganic acid alone is not satisfactory because the drug solubility is not sufficiently improved and the drug uniformity in the non-aqueous base is not sufficient. Moreover, what mix | blended the organic acid has high reactivity with loxoprofen sodium, and is inferior to what mix | blended the inorganic acid in the point of storage stability. Therefore, when an organic acid is blended, the solubility of loxoprofen sodium is improved and the storage stability is ensured by the combined use with the pyrrolidone compound (Patent Document 2) and the combined use with the solubilizer (Patent Document 3). A method for preparing an external patch is disclosed. However, in these methods, there is a problem in the adhesive force required as a tape agent, and the preparation that achieves the purpose has not been developed.
Therefore, it has been desired to develop a loxoprofen sodium-containing tape having high drug solubility, high storage stability, and excellent adhesiveness.

The loxoprofen sodium containing tape agent excellent in the usability can be provided.

以下、本発明のロキソプロフェンナトリウム含有テープ剤を詳細に説明する。なお、本明細書に記載の例示は、本発明を特に限定するものではない。   Hereinafter, the loxoprofen sodium containing tape agent of this invention is demonstrated in detail. Note that the examples described in the present specification do not particularly limit the present invention.

The present invention is an external patch containing loxoprofen sodium in a non-aqueous base such as a tape.
The “drug solubility” of the present invention means that the drug solubility is stable with respect to those in which crystals are not observed even after 30 days or more after production when the presence or absence of crystal precipitation of the drug or a salt thereof is observed in the test preparation. It was judged that a uniform preparation was obtained.

本発明の「保存安定性」とは、被験製剤を60℃で4週間保存し、保存開始時のロキソプロフェンナトリウム含有量を100%とした場合の4週間後の含有率%を意味する。また、60℃で4週間後に含有率が90%以上のものを保存安定性が高く維持されていると判断する。   The “storage stability” of the present invention means the content% after 4 weeks when the test preparation is stored at 60 ° C. for 4 weeks and the content of loxoprofen sodium at the start of storage is 100%. Moreover, it is judged that the storage stability is kept high when the content is 90% or more after 4 weeks at 60 ° C.

本発明の「粘着性」とは、被験製剤を縦12mm×横80mmに裁断した帯状の試験片を、鋼板の試験板に一端を合わせて速やかにはり付け、1分間300mmの速さで90度の角度で剥がす際の応力を意味する。このとき、応力が50g未満では皮膚への粘着性が十分ではなく、製剤が簡単に剥がれ落ちてしまい、また、100gより高い製剤では皮膚への粘着性が強過ぎて、かぶれや剥がす際の痛みなどの問題が発生するため、好ましくない。よって50〜100gの応力を示すものを粘着性が優れていると判断する。   The “adhesiveness” of the present invention means that a strip-shaped test piece obtained by cutting a test preparation into a length of 12 mm × width of 80 mm is fastened by attaching one end to a steel plate test plate at a speed of 300 mm for 1 minute.

Preferably, it is 2-7 mass%. When the content of loxoprofen sodium is less than 1% by mass in the adhesive base, the amount of permeation through the skin necessary for showing medicinal effects cannot be obtained, which is not preferable. On the other hand, when the content is more than 10% by mass in the adhesive base, the drug is not sufficiently dissolved in the tape base and a uniform preparation cannot be obtained, which is not preferable.

本発明に用いるヒドロキシカルボン酸は、ロキソプロフェンナトリウムを含有した非水系粘着剤に溶解若しくは溶融し、均一に混合されるものであれば特に限定されるものではない。好ましくは、融点が60℃以下のヒドロキシカルボン酸であり、最も好ましいヒドロキシカルボン酸は、乳酸である。また、これらのヒドロキシカルボン酸はD体、L体、DL体の光学異性体を含むものである。
本発明に用いられるヒドロキシカルボン酸の粘着基剤中での含量は、特に制限はないが、0.3〜3.0質量%が最も好ましい。ヒドロキシカルボン酸の含量が、0.3質量%より少ない場合、十分な薬物溶解性が発揮されないため、好ましくない。また、3.0質量%より多い場合、薬物溶解性は得られるが、保存安定性が低下し、好ましくない。
The hydroxycarboxylic acid used in the present invention is not particularly limited as long as it is dissolved or melted in a nonaqueous adhesive containing loxoprofen sodium and mixed uniformly. Preferably, it is a hydroxycarboxylic acid having a melting point of 60 ° C. or less, and the most preferred hydroxycarboxylic acid is lactic acid. These hydroxycarboxylic acids include optical isomers of D-form, L-form and DL-form.
Although there is no restriction | limiting in particular in the content in the adhesive base of the hydroxycarboxylic acid used for this invention, 0.3-3.0 mass% is the most preferable. When the content of hydroxycarboxylic acid is less than 0.3% by mass, sufficient drug solubility is not exhibited, which is not preferable. On the other hand, when it is more than 3.0% by mass, drug solubility can be obtained, but storage stability is lowered, which is not preferable.

本発明に用いうる脂肪酸としては、炭素数12〜18を有する脂肪酸であれば特に限定されるものではないが、イソステアリン酸、ステアリン酸、パルミチン酸、ラウリン酸、ミリスチン酸、オレイン酸およびリノール酸などが挙げられる。その中でも、イソステアリン酸、ステアリン酸、パルミチン酸が特に好ましい。
本発明に用いられる脂肪酸の粘着基剤中での含量は、特に制限はないが、1〜5質量%が好ましい。1質量%より少ないと、十分な薬物溶解性が得られず、好ましくない。また、5質量%より多いと、保存安定性が低下し、粘着性が低下するなど粘着剤の物性に影響を及ぼすため、好ましくない。
The fatty acid that can be used in the present invention is not particularly limited as long as it has 12 to 18 carbon atoms, but isostearic acid, stearic acid, palmitic acid, lauric acid, myristic acid, oleic acid, linoleic acid, etc. Is mentioned. Among these, isostearic acid, stearic acid, and palmitic acid are particularly preferable.
Although there is no restriction | limiting in particular in the content in the adhesive base of the fatty acid used for this invention, 1-5 mass% is preferable. When it is less than 1% by mass, sufficient drug solubility cannot be obtained, which is not preferable. On the other hand, when the content is more than 5% by mass, the storage stability is lowered and the physical properties of the pressure-sensitive adhesive are affected.

本発明のテープ剤の粘着基剤成分としては、テルペン樹脂が用いられることが好ましい。テルペン系樹脂としては、YSレジン、YSレジンPX、YSレジンPXN、YSポリスター、マイティエース、YSレジンTO、YSレジンTR、クリアロンP、クリアロンM、クリアロンK、ダイマロン、YSオイルDA(ヤスハラケミカル(株))、タマノル803L、タマノル901(荒川化学工業(株))などが例として挙げられる。
該テルペン樹脂は、一般に粘着付与剤として使用されるもので、ゴム系粘着基剤との相溶性があり、ロキソプロフェンナトリウムの溶解性を改善するという作用もある。一般的な粘着付与剤として、他にロジン系樹脂などがあるが、ロジン系樹脂を使用した場合、ロキソプロフェンナトリウムの含量が経時的に低下するため、好ましくない。
本発明に用いられるテルペン樹脂の粘着基剤中の含量は、特に制限はないが、テープ剤の組成物全体の10〜20質量%が最も好ましい。10質量%より少ないと、十分な粘着性が得られず、製剤の剥がれ落ちや剥がれ捲れなどの問題が発生するため、好ましくない。また、20質量%より多い場合、皮膚への粘着性が強過ぎて、かぶれや剥がす際の痛みなどの問題が発生するため、好ましくない。

The terpene resin is generally used as a tackifier, is compatible with a rubber-based adhesive base, and has an effect of improving the solubility of loxoprofen sodium. Other common tackifiers include rosin resins, but the use of rosin resins is not preferable because the content of sodium loxoprofen decreases with time.
The content of the terpene resin used in the present invention in the adhesive base is not particularly limited, but is most preferably 10 to 20% by mass of the entire composition of the tape. When the amount is less than 10% by mass, sufficient tackiness cannot be obtained, and problems such as peeling off of the preparation and peeling off of the preparation occur. On the other hand, when the content is more than 20% by mass, the adhesiveness to the skin is too strong, and problems such as rash and pain at the time of peeling off are not preferable.
