Definitions
- the present invention relates to a percutaneously absorbable external anti-inflammatory analgesic preparation, and more particularly to a felbinac-containing anti-inflammatory analgesic external patch having good drug release, low skin irritation and high drug stability.
- Felbinac (Felbinac: 4-biphenylacetic acid) is an active metabolite of the non-steroidal anti-inflammatory analgesic agent fenbufen, and is a drug exhibiting a strong anti-inflammatory analgesic action. Since felbinac has the problem of causing side effects in the digestive system and causing gastrointestinal disorders when administered orally, it has been studied as a percutaneous absorption preparation. To date, gels, liquids, etc. External preparations are commercially available.
- aqueous patches (patches) and oil-based patches (plasters) containing various anti-inflammatory analgesics such as felbinac have been developed.
- oil-based patches (plasters) have become mainstream as non-steroidal anti-inflammatory analgesic patches for reasons such as no cooling sensation when applied, and combined a rubber base and a tackifying resin. Prescriptions are widely used.
- L-menthol is useful as a solubilizing agent for felbinac and is an additive blended in many commercially available felbinac-containing patches.
- fervinac reacts with L-menthol to produce an L-menthol ester which is a decomposition product, and the formulation of L-menthol stabilizes ferbinac in the patch. It is one of the causes of sexual deterioration.
- many people feel uncomfortable with the irritating odor associated with sublimation of L-menthol and it is also true that there is a high demand for patch preparations that do not contain L-menthol or suppress L-menthol odor in the market. .
- Patent Document 1 proposes a felbinac-containing patch having a pressure-sensitive adhesive layer containing crotamiton, which is excellent in dissolving ability for felbinac, as an essential component.
- crotamiton has a problem that it tends to bleed out on the surface of the pressure-sensitive adhesive layer, and the adhesive force decreases with time.
- Patent Document 2 discloses an anti-inflammatory analgesic tape agent containing felbinac, in which styrene-isoprene-styrene block copolymer is used as an adhesive and L-menthol and various absorption accelerators are combined.
- L-menthol blended with this tape may react with ferbinac to produce a decomposition product, and in addition, by combining L-menthol and an absorption accelerator.

- a patch containing various percutaneous absorption accelerators such as felbinac patch containing a combination of N-methyl-2-pyrrolidone and polyethylene glycol (Patent Document 4) and one containing hardened oil (Patent Document 5). Although agents have been studied, no percutaneously absorbable preparations having both high percutaneous absorption and safety of drugs and excellent drug stability have been found.
- Patent Document 6 discloses a water-containing plaster agent in which lanolin is blended in an adhesive base based on a styrene-isoprene-styrene block copolymer so that the lanolin retains moisture. This is an attempt to increase the solubility of felbinac by the moisture contained in the preparation and, as a result, improve the transdermal absorbability.
- the inclusion of moisture in the oily patch makes the manufacturing process complicated.
- the possibility of deterioration of physical properties of the preparation during storage cannot be denied.
- percutaneous absorption there is a problem that it is slightly inferior to a plaster using a transdermal absorption enhancer.
- Patent Document 7 proposes a patch in which felbinac is uniformly dispersed in an adhesive base containing rosin-based resin and the like based on styrene-isoprene-styrene block copolymer without using crotamiton.
- the rosin resin blended in the patch acts as a skin sensation preparation, and the blending is undesirable.
- Skin sensitization is a type of delayed hypersensitivity reaction, which is a phenomenon in which an excessive immune reaction is caused by a chemical substance, causing skin irritation and the like.
- the present invention solves the above-mentioned problems, and exhibits high drug release without blending L-menthol, which is an excellent solubilizing agent for felbinac, and has low skin irritation and high drug stability.

Abstract
Description
このようなゲル剤、液剤の問題点を改善するために、フェルビナクを初め、様々な消炎鎮痛薬を含有する水性貼付剤(パップ剤)や油性貼付剤(プラスター剤)が開発されている。とりわけ、油性貼付剤(プラスター剤)は、貼付時の冷感がない等の理由から、非ステロイド系消炎鎮痛貼付剤として主流となってきており、ゴム系基剤と粘着付与樹脂とを組み合わせた処方のものが汎用されている。
また、L-メントールの昇華に伴う刺激臭を不快と感じる人も多く、市場においてもL-メントールを配合しない、或いはL-メントール臭を抑えた貼付製剤の需要が高いことも、また事実である。
例えば特許文献1には、フェルビナクに対する溶解能力に優れているクロタミトンを必須成分として含有させた粘着剤層を有するフェルビナク含有貼付剤が提案されている。しかしながら、クロタミトンは、粘着剤層の表面にブリードアウトしやすく、経時的に粘着力が低下する、という問題を有している。
その他、N-メチル-2-ピロリドンとポリエチレングリコールを組み合わせて配合したフェルビナク貼付剤(特許文献4)、硬化油を配合するもの(特許文献5)等、様々な経皮吸収促進剤を配合した貼付剤が検討されてきているが、高い薬物の経皮吸収性と安全性、および優れた薬物の安定性を兼ね備えた経皮吸収製剤は見当たらない。
例えば、特許文献6は、スチレン-イソプレン-スチレンブロック共重合体をベースとした粘着剤基剤中にラノリンを配合し、ラノリンに水分を保持させる含水型のプラスター剤が開示されている。
これは製剤中に含有される水分によってフェルビナクの溶解性を高め、その結果、経皮吸収性を向上させようという試みであるが、油性貼付剤中に水分を含有させることは製造工程を複雑なものとし、また保存中の製剤の物性低下の可能性を否定しきれないものである。
加えて経皮吸収性の面では、経皮吸収促進剤を使用したプラスター剤と比較するとやや劣るという問題がある。
しかしながら、本貼付剤に配合されるロジン系樹脂は、皮膚感作成分として作用し、その配合は望ましくないことが知られている。皮膚感作とは、遅延性過敏反応の一種で、化学物質により過剰な免疫反応が起こり、皮膚にかぶれ等が起こる現象のことである。
本発明が提供するフェルビナク含有外用貼付剤は、フェルビナクの優れた消炎鎮痛効果により、例えば、変形性関節症、慢性関節リウマチ、腰痛症、肩関節周囲炎、腱鞘炎、腱周囲炎、上腕骨上顆炎(テニス肘等)、筋肉痛、外傷後の腫脹・疼痛などの予防、治療に有用である。
すなわち、本発明にあっては、有効成分としてのフェルビナクについて、特に、平均粒子径が5μm以上であり、かつ100μm未満のフェルビナクを用い、粘着基剤層に分散させることを特徴とする。
粘着剤中のフェルビナク配合量が0.1重量%未満であると、経皮吸収性が不十分であり、効果が認められず、また、10重量%を超えて配合しても、それ以上の効果が認められず、経済的に不利であり好ましくない。
その平均粒子径が5μm未満であると製造工程においてフェルビナク原薬が二次凝集を起こし、均一に分散しない虞があり、薬物の経皮吸収性の低下を招く。反対に平均粒子径が100μm以上であると、粘着剤中で薬物が均一に分散しない可能性がある。特に粒子径が大きい場合は、薬物の経皮吸収性の低下はもとより、製造工程、特に粘着剤の剥離フィルムへの塗工工程において好ましくない影響がみられる。すなわちフェルビナク原薬が製造中に凝集し、それが原因による、粘着剤表面の凹凸が見られる場合がある。
その配合量は、製剤化が可能である限り特に限定はないが、好ましくは粘着剤重量に対して、10~50重量%の範囲内で配合するのがよい。
粘着剤中の脂環族飽和炭化水素樹脂の含量が10重量%未満であると粘着力が弱く、50重量%を超えて配合すると、製剤の粘着力が強くなり、剥離時に痛みを伴うといった問題がある。
粘着剤中のセバシン酸ジエチルの配合量が0.1重量%未満であるとフェルビナクの皮膚透過性が不十分であり、10重量%を超えて配合すると、皮膚刺激等の問題が生じ、好ましいものではない。
配合比率が1:0.1未満であるとセバシン酸ジエチルによる吸収促進効果が得られず、十分な薬物吸収性が得られない。また、配合比率が1:15を超える場合には、フェルビナクが過剰なセバシン酸ジエチルに溶解し、薬物安定性が低い製剤となる。
軟化剤の配合量は、粘着剤重量に対して10~75重量%、好ましくは15~60重量%、より好ましくは20~50重量%の範囲内で配合するのがよい。
すなわち、粘着剤層を構成するSIS、軟化剤、および脂環族飽和炭化水素樹脂、酸化防止剤を加熱溶解する。次いで、有効成分であるフェルビナクとセバシン酸ジエチルを前記粘着基剤に加え、撹拌・混合し、貼付剤における粘着剤を調製する。
次いで、調製された粘着剤(膏体)を、シリコーン処理されたポリエチレンテレフタレートフィルム上に塗工し、厚み50~300μmの粘着剤層を形成する。得られた粘着剤層に支持体のポリエステル製織布または不織布をラミネートした後、適当な大きさと形状に切断して、本発明の外用貼付剤を得ることができる。
なお、実施例及び比較例における各表中の配合成分の配合量は、特に断らない限り重量%で表示している。
SIS、ポリブテン、流動パラフィン、ジブチルヒドロキシトルエンを170℃加温条件下にて練合、溶融させた後、さらに脂環族飽和炭化水素樹脂を添加し、130℃加温条件下にて練合、混和し粘着基剤を作製した。
別にセバシン酸ジエチルと適量の流動パラフィンを混和した液中に平均粒子径が5μm以上であり、かつ100μm未満のフェルビナクを攪拌しながら均一に分散し、フェルビナク分散液を調製した。このフェルビナク分散液を上述の粘着基剤に添加し、均一に分散するまで練合し、粘着剤を調製した。粘着剤をシリコーン処理されたポリエチレンテレフタレートフィルム上に100μm厚で塗工後、ポリエステル織布とラミネートし、試験製剤を得た。
実施例1と同様の手順で、表1~表3に示す成分組成により、目的とする本発明の貼付剤を作製した。
下記表4に示す成分組成に変更する他は、実施例1と同様の手順で各比較例の外用貼付剤を作製した。
なお比較例7の製剤は、製造時(粘着剤調製時)にフェルビナク原薬が凝集し、それが原因で製剤表面の凹凸が見られ、以下の製剤評価試験を行うことができなかった。
実施例1~2と比較例1~2の製剤を、各々φ25mmに打ち抜き、健常男子15名の上腕内側に24時間貼付し、剥離後1時間、及び24時間目の皮膚刺激性を判定した。
その結果を、下記表5に示した。
実施例1と比較例3~4の製剤を各々5cm×7cmに打ち抜き、健常男子6名の背部に12時間貼付し、回収した製剤中に残存する薬物を抽出し、薬物量をHPLCで測定した。
0時間貼付の薬物量から残存薬物量を差し引いて、薬物消失量を計算した。その結果を下記表6に示した。
実施例1、比較例2及び比較例5のサンプル(7cm×10cm)を40℃で3ヶ月間保存した後、試験製剤中の薬物を抽出しフェルビナク含量を測定した。
試験前の各サンプルのフェルビナク含量(初期値)と比較し、対初期値(%)として算出した。その結果を表7に示した。
実施例1、実施例16及び比較例6の各製剤を、各々φ20mmに打ち抜き、100mL容ビーカーの内側側面に、両面テープを使用して粘着剤面がビーカーの内側に面するように貼付した。
製剤の貼付位置は製剤の最も下端の部分がビーカーの底から約30mmの位置となるように調整した。その後、ビーカーの内側に100mLの放出溶液(PBS緩衝溶液)を注ぎ入れ、マグネチックスターラーで放出溶液を攪拌した。そして試験開始90分後の放出溶液中のフェルビナク含量を高速液体クロマトグラフ法により測定し、主薬の放出率を算出した。その結果を表8に示した。
本発明の外用貼付剤は例えば、変形性関節症、慢性関節リウマチ、腰痛症、肩関節周囲炎、腱鞘炎、腱周囲炎、上腕骨上顆炎(テニス肘等)、筋肉痛、外傷後の腫脹・疼痛などの予防、治療に有用であり、その利用性は多大なものである。
