Abstract
Description
錠剤を嚥下しやすいものとするために、錠剤の滑りやすさ、のどへの引っ掛かりにくさ等を改良することが求められる。この点を考慮して錠剤等の固形製剤のコーティングを工夫した技術がこれまでに複数報告されている(特許文献1~3)。しかしながら、コーティングによって錠剤表面が滑りやすくなり、ある程度は服用性が向上しても、複雑な形状をした咽頭部を通過する際の抵抗は依然大きく、嚥下改善効果は十分ではない。
水性液と接触することで表面の潤滑性が増すようになされている、固形製剤を提供するものである。
本実施形態の固形製剤は、経口摂取する固形製剤であって、水性液と接触することで表面の潤滑性が増すようになされている。ここでいう水性液とは、水、茶、清涼飲料、牛乳等の通常飲用に用いる液体、唾液、又はこれらの混合物を指す。本発明の固形製剤は、ゲル化剤を含有しているため、水性液と接触することで表面の潤滑性が増大する。固形製剤はその表面部にゲル化剤を含有していることが好ましい。本実施形態の固形製剤は、服用前の状態ではゲル化剤がゲル化しておらず、服用に際して水性液に触れることでゲル化剤がゲル化するようになされている。ゲル化剤としては、粉状(粒子状)であって、水性液を含んだときにぬめり性を発揮する物質を用いる。本明細書においてゲル化とは、ゲルの存在が確認できることを必須とするものではなく、ゲル化剤が水性液と接触することにより、ぬめり性を発揮していればよい。しかしながら、水性液との接触により実際にゲルの存在が確認できることが好ましい。具体的には、プラスチック製の基板上に固形製剤を静置し、固形製剤の表面積1mm2あたり、25℃の水0.2μLをスポイトで滴下し、その状態で10~20秒間保持した後に、ゲルの存在を確認できることが好ましい。
上下方向に沿って配置され且つ上下方向に移動可能に固定されたシリコンチューブと、該シリコンチューブを左右方向に挟んだ状態で固定された一対のスリットとを用い、該シリコンチューブにおける該スリットの下側に、固形製剤を1錠充填し、該シリコンチューブを該スリットに沿って上方に移動させることで該シリコンチューブを該固形製剤に対して上方に速度0.5mm/秒で20mm移動させた時の最大応力を測定する。なお、前記測定に用いるシリコンチューブとしては、シリコンチューブの断面積が固形製剤の断面積よりも小さく、かつ、固形製剤の断面積の40%よりも大きいものを使用する。固形製剤の断面積のシリコンチューブの断面積に対する割合は40%以上60%以下であることが好ましく、45%以上55%以下であることがより好ましい。
上記のシリコンチューブの断面積とは、固形製剤を充填していない状態におけるシリコンチューブをその長手方向と直交する方向で切断した断面におけるシリコンチューブ内面に囲まれた部分の面積を指す。
また、固形製剤の断面積とは、シリコンチューブに充填された状態における固形製剤の、シリコンチューブの長手方向と直交する面で切断した断面のうち、最大面積を有する断面の面積を指す。
6本のガラス管を有する崩壊試験器の該ガラス管それぞれに、固形製剤を1粒ずつ入れる。各ガラス管は、上下面が開口しており、ガラス管の下面には網目の開き1.8mm~2.2mmのステンレス網が取り付けられている。固形製剤を入れたガラス管を37±2℃の水中に入れ、崩壊試験器を作動させる。崩壊試験器中のガラス管を観察し、固形製剤が崩壊しかかっている様子が確認されたらガラス管を引き上げ、固形製剤の崩壊の様子を観察する。この作業を繰り返し、固形製剤が完全に崩壊するまで観察する。崩壊試験器を作動させたときから、6個の固形製剤全てが崩壊したときまでの時間を測定し、該測定された時間を崩壊時間とする。尚、固形製剤の残留物をガラス管内に全く認めないか、又は認めても明らかに原形をとどめない軟質の物質であるとき固形製剤は崩壊したものとする。
錠剤はゲル化剤を有する裸錠を有する錠剤であることが好ましい。一般に、裸錠(素錠ともいう)とは、その表面にコーティング層が形成されていない錠剤を指す。本明細書において「裸錠を有する錠剤」とは、錠剤の表面においてコーティング層の形成されていない部分があり、当該部分が裸錠の状態である錠剤のことを意味する(以下、錠剤表面のコーティング層が形成されていない部分を裸錠部分という)。また、本明細書において「裸錠」とは、表面にコーティング層が実質的に形成されていない錠剤(錠剤の表面積に占めるコーティング層によって被覆される面積の割合が5%未満の錠剤)を意味する。本明細書において「裸錠」は、「裸錠を有する錠剤」に包含される概念である。
以下の固形製剤の成分及び組成は、固形製剤が錠剤である場合は錠剤中に含まれる成分及び組成であり、固形製剤がカプセル剤の場合はカプセル中に含まれる成分及び組成である。特に固形製剤が裸錠を有する錠剤であり、以下の固形製剤の成分及び組成が錠剤を構成する裸錠中に含まれる成分及び組成に該当することが好ましい。
前記の誘導体としては、ヒアルロン酸誘導体、アルギン酸誘導体及びポリグルタミン酸誘導体等が挙げられる。また、前記の塩としては、アルギン酸塩、ヒアルロン酸塩、ポリグルタミン酸塩等が挙げられる。ヒアルロン酸誘導体としてはヒアルロン酸エステル、アセチル化ヒアルロン酸等が挙げられる。アルギン酸誘導体としてはアルギン酸エステル等が挙げられる。ポリグルタミン酸誘導体としては、ポリグルタミン酸エステル等が挙げられる。アルギン酸塩としてはアルギン酸ナトリウム、アルギン酸カリウム、アルギン酸アンモニウム及びアルギン酸カルシウム等が挙げられる。ヒアルロン酸塩としてはヒアルロン酸ナトリウム及びヒアルロン酸カリウム等が挙げられる。ポリグルタミン酸塩としては、ポリグルタミン酸ナトリウム及びポリグルタミン酸カリウム等が挙げられる。ゲル化剤は1種のみを単独で用いてもよく、2種以上を組み合わせて用いてもよい。
また、ゲル化剤を2種以上組み合わせることも崩壊性とぬめり性との両立を図る点や、製造性の観点で好ましく、特定のゲル化剤と特定のゲル化剤以外のゲル化剤を組み合わせることがさらに好ましい。具体的には、特定のゲル化剤であるローカストビーンガムと、特定のゲル化剤以外のゲル化剤であるキサンタンガム、グァーガム、アルギン酸、カラギーナン等を組み合わせることが好ましい。例えば、キサンタンガム又はグァーガムに、ローカストビーンガムを組み合わせることでぬめり感による嚥下しやすさを効果的に高めることができる。またグァーガムに、ローカストビーンガムを組み合わせることで、摂取後における体内での崩壊性に優れた固形製剤を得ることができる。
また、糖アルコール、二糖類を含有することは、固形製剤の原料粉末の結着性を高め、固形製剤が錠剤である場合、打錠した錠剤の硬度が得られるなどの製剤のしやすさや、有効成分の不快味のマスキング効果が得られる点でも好ましい。
また後述するように表面がゲル化剤によって被覆された糖アルコール及びゲル化剤を含む粒子を非含有である条件の下、糖アルコールを、キサンタンガム、ローカストビーンガム及びグァーガム並びにこれらの塩及び誘導体から選ばれる少なくとも1種と組み合わせることも、硬度や飲みやすさと滑りやすさに優れ、嚥下が容易な固形製剤をより一層得やすい点で好ましい。また後述するようにゲル化剤の被覆層を非含有である条件の下、デンプンとキサンタンガム、ローカストビーンガム又はグァーガム並びにこれらの塩及び誘導体から選ばれる少なくとも1種以上から構成されるゲル化剤と還元麦芽糖を含む固形製剤であることも好ましい。

〔実施例1〕
原料粉末として、表1の配合比に従い、400粒分の各種原料(ステアリン酸カルシウムを除く)をビニール袋内で混合した後、篩を通し、さらにステアリン酸カルシウムを添加、混合した。この混合粉末をロータリー打錠機(菊水製作所)で直接打錠して、円盤型の裸錠を得た。得られた裸錠の硬度をシュロイニゲル錠剤硬度計で測定した。また、得られた裸錠の錠径(直径)、錠厚をデジタルノギス(デジマチックキャリパCD-15AX;ミツトヨ)で測定したところ、硬度7.4kgf、錠径10mm、錠厚3.52mmであった。また、得られた裸錠1粒の重量を測定したところ、270mgであった。なお、硬度、錠径、錠厚及び重量は、3粒それぞれの測定値の平均値である。
表1の配合比に従い、原料粉末の配合比率を変更した以外は、実施例1と同様にして裸錠を得た。得られた裸錠について実施例1と同様の測定を行ったところ、硬度7.7kgf、錠径10mm、錠厚3.50mm、重量270mgであった。
実施例1及び2で得られた裸錠について、服用時の喉の筋電位測定と服用感アンケートとを単盲検クロスオーバーにて実施した。
また、錠剤の滑りやすさを評価するため斜面滑落時間を測定した。
被験者は錠剤を飲むのが苦手との自覚がある健常な成人6名を選出した(男女比は2:4)。服用方法は、まず対象となる裸錠4粒を口に含んだ後に22℃の水20mLを口に含み、裸錠を水と一緒に服用することとした。
筋電位測定は、筋電計(AM科学株式会社製ワイヤレス筋電計測・分析システム「Lateo」)を用いた。測定方法は筋電計に付属のマニュアルに従ったが、具体的には、以下の通りに行った。筋電計の電極を喉に装着し、喉を馴化させるため、裸錠を服用する際と同量の水20mLを被験者に服用させた。次に、水20mLを服用した際の喉の筋電位を測定した。その後、裸錠4粒を口に含んだ後に、水20mLで服用した際の喉の筋電位を各試験区についてそれぞれ測定した。筋肉活動量は得られた筋電位(単位ボルト(V))に基づいて算出された積分値から、水のみを服用したときの筋肉活動量を100(%)とした時の相対値を求めた。一人当たり1回の相対値を合算し、人数で割った値を、筋肉活動量(%)とした。なお、図1~図3において1Countは1/200秒である。
なお、各試験区の測定は、約5分の休息時間を空けて行い、裸錠を服用する順番は被験者ごとに変更した。
滑りやすさは、錠剤を服用した際に引っかかり、喉を進んでいかない程度に滑りが無く飲みにくい場合を最低評価(-3点)とし、喉への摩擦が感じられず、喉に引っかかることが無い程度に滑りやすく飲みやすい場合を最高評価(3点)とする7段階で評価させた。
べたつきは、舌や咽頭部で付着を感じる程度にべたついて飲みにくい場合を最低評価(-3点)とし、舌や咽頭部で付着せず、ぬめりだけを感じる程度にべたつきが無く飲みやすい場合を最高評価(3点)とする7段階で評価させた。
30°に傾斜させて固定した断面U字状のアルミチャンネル(側面視で直線状、チャンネル長さ90cm、幅1.2cm)に、チャンネル上部から毎分150mlの水を供給した。この状態で、チャンネルの上端部より10cm下の位置から裸錠1粒を滑らせて流し、下端部までの80cmを滑走するのに要した時間(秒)を測定した。試験は5回行い、5回の平均値を算出し、斜面滑落時間(秒)とした。
アンケートにより得られた評価点について6人の平均値及び斜面滑落時間(秒)の測定結果を表1に示す。なお、表1において、裸錠の組成の単位は質量部である。
なお、クロスポビドン、カルボキシメチルスターチナトリウム、クロスカルメロースナトリウム又は低置換度ヒドロキシプロピルセルロースを配合した裸錠では、実施例1又は2に比べると滑りやすさ及びべたつきにくさが低下する。
なお、クロスポビドン、カルボキシメチルスターチナトリウム、クロスカルメロースナトリウム又は低置換度ヒドロキシプロピルセルロースを配合した裸錠は、実施例1又は2に比べると斜面滑落性が低下する。
〔実施例3~6〕
下記表1の配合比に従い、硬度を9kgfに、錠径9mm、錠厚4.81~5.08mm(実施例3は4.81mm、実施例4及び6は4.89mm、実施例5は5.08mm)に、重量を300mgに変更した以外は、実施例1と同様にして裸錠を得た。
下記の方法により、得られた裸錠について崩壊時間の測定を行った。結果を表2に示す。
第十五改正日本薬局方における項目「6.09」の「崩壊試験法」に記載の方法で、崩壊試験器 (富山産業株式会社、型番:NT-40H)を用いて、n=6で崩壊時間を測定した。なお、溶液は水を用いた。
〔実施例7~14、16~21、比較例1〕
下記表3の配合比に従い、実施例1と同様にして、裸錠を得た。得られた実施例7~14、16~21、比較例1の裸錠は、硬度、錠径、錠厚ともに実施例3~5と同程度であり、重量300mgであった。
ソルビトール57.1質量部、マルトース30.0質量部を流動層造粒機(流動層造粒乾燥・コーティング機 型式:FD-LAB-1型、パウレック社)に投入し、結晶セルロースの懸濁液を噴霧後、さらに、キサンタンガムを熱水で希釈し0.1%(w/v)にした懸濁液を噴霧することによって造粒し、ソルビトール及びマルトースの混合粉末からなる粒子表面にキサンタンガムの被覆層が形成された粒子組成物(表面がゲル化剤によって被覆された糖アルコール及びゲル化剤を含む粒子)を得た。
得られた粒子組成物に、ステアリン酸カルシウム0.5質量部を混合後、ロータリー打錠機(菊水製作所)を用いて打錠し、硬度、錠径、錠厚ともに実施例3~5と同程度であり、重量300mgの裸錠を得た。裸錠中の結晶セルロース及びキサンタンガムの量は、表1に示す量であった。
裸錠をプラスチック製の基板上に静置し、裸錠の表面積1mm2あたり、25℃の水0.2μLをスポイトで滴下し、その状態で15秒間保持した。
長手方向が上下方向と一致するように上下方向に沿って配置され且つ上下方向に移動可能に固定された内径9mm、外径11mmのシリコンチューブと、該シリコンチューブを左右方向に挟んだ状態で固定された一対のスリットとを用い、該シリコンチューブにおける該スリットの下側に、前記裸錠(錠径9mm)を1粒充填した。該シリコンチューブを該スリットに沿って、該裸錠に対して上方に速度0.5mm/秒で20mm移動させた時の最大応力を株式会社 山電製クリープメータ(RE2-33005C)を用いて測定した。測定に用いたシリコンチューブの断面積は、裸錠の断面積の50%であった。応力が20を超えた場合にはその時点で測定を終えた。シリコンチューブとしては、扶桑ゴム産業社製クリアシリコーン角チューブを用いた。スリットとしては、株式会社 山電製の特殊円柱押出治具(AT-43446)を用い、これを互いの最小間隔が2mmとなる位置に固定させた。
最大応力は3連の平均値として求めた。
また、実施例7~14の結果から、特定の賦形剤の中でも、単糖類、二糖類、オリゴ糖又はデンプン分解物を含む裸錠の場合、最大応力が特に低いことが判る。
内容液(サフラワー油95質量%、ミツロウ5質量%)を調製し、グリセリン16.4質量%、精製水36.8質量%、ゼラチン43.3質量%及びカラメル色素3.5質量%の割合で含むカプセル皮膜(乾燥前の重量)に充填することでソフトカプセルとした。カプセル化は、カプセル皮膜液を流延しフィルム化すると共に、内部に内容液を充填しヒートシールし、成形されたソフトカプセルを乾燥させることによって行った(1粒あたり300mg)。ソフトカプセル1粒に対して、ローカストビーンガム(粉末)の重量が5mgとなるように、ソフトカプセルとローカストビーンガムを混合し、ローカストビーンガムを付着させた。この工程により、表面の一部にゲル化剤が付着したソフトカプセルを得た。
