Description

技術分野
本発明は、口腔内崩壊型組成物及び口腔内崩壊型製剤に係り、更に詳細には、製剤の取扱い上必要な強度を有し、しかも口腔内において速やかに崩壊する口腔内崩壊組成物、及びこれを用いた口腔内崩壊型製剤に関する。
背景技術
高齢化社会の到来に当たり、老化に関する多方面からの研究開発が盛んに行われるようになり、その一分野として、高齢者に投与最適な新規製剤についての調査研究報告がなされている。この調査研究報告では、内服薬の自己服薬の可否、服用する際に摂取する飲食物、及び剤形の服用性について調査が行われており、また、現在使用されている剤形の中で最も服用しやすい剤形、将来希望する剤形及び内服薬の味の嗜好についても患者の希望が調査された。
かかる調査研究報告によって、高齢者が医薬品の服用において剤形の面から多くの問題点を抱えていることが指摘され、この結果、現在用いられている剤形の多くは一般成人向けのものであることから、介添えを必要とする身体不自由な高齢者でも容易に服用でき、更に服用しにくさから服用拒否を示す高齢者のためにも服用しやすい剤形の開発が望まれるようになった。また、高齢者でも容易に服用できる剤形は、小児や一般成人にとっても好ましいものである。
更に、この調査研究報告によれば、高齢者にとって好ましい新規製剤として、口腔内崩壊型製剤、ペースト状製剤及びゼリー状製剤が提案されているが、特に口腔内崩壊型製剤はその流通過程での安定性等を考慮すると最も現実的な製剤であると考えられており、この観点から、このタイプの製剤がさかんに検討・開発されている。
上述のような背景において、特公昭62−50445号公報には、ゼラチン、デキストリン、加水分解デキストリン又はアルギネート、又は上記物質1種以上とポリビニルアルコール、ポリビニルピロリジン又はアラビアガムとの混合物、又はポリビニルアルコールとポリビニルピロリジンとの混合物又はアラビアガムとポリビニルピロリジンとの混合物から選んだ医薬的に許容可能な水溶性又は水分散性重合体単体物質のネットワークを含み、そして10〜200mg/mlの密度を有する、経口投与用の固形医薬剤形が記載されている。
しかしながら、かかる製剤は、凍結乾燥により調製されるため、凍結乾燥のための製造設備が必要であり、コスト高となる。また、凍結乾燥で得られた製剤は強度が小さいため、一般に取扱が不便であるという課題がある。
また、国際公開WO93/12769号には、活性成分と乳糖及び/又はマンニトールからなる糖類と、固形成分に対し、0.12〜1.2w/w%の寒天からなる密度が400mg/ml乃至1000mg/mlである製剤取扱い上十分な強度を有する口腔内崩壊性の固形製剤が記載されている。
しかしながら、この固形製剤の製造方法は、懸濁液を鋳型に流し込み、この懸濁液を乾燥するというものであり、一般の錠剤の製造方法と異なり煩雑であるという課題がある。
国際公開WO95/20380号には、成形性の低い糖及び成形性の高い糖類を含有してなる、口腔内において速やかな崩壊性、溶解性を有する口腔内溶解型圧縮成型物が記載されている。
しかしながら、この圧縮成型物を製造するに当たっては、成形性の高い糖類が造粒物の表面にあるため、打錠時にスティッキング等の打錠障害が発生するという課題が残されている。
特開平9−48726号公報には、薬物及び加湿により成形可能に湿潤し且つ成形後の乾燥により該形状を維持する物質からなり、これら成分が低密度で加湿、成形されることにより崩壊容易に構成されてなる口腔内速崩壊性製剤が記載されている。また、特開平8−291051号公報には、薬剤、水溶性結合剤及び水溶性賦形剤を含む乾燥状態の錠剤材料を錠剤の形態として次段の製造工程へ移行させる際にその形態を維持可能な硬度をとるために、最低必要な低圧力で加圧成形する打錠工程と、上記打錠工程で成形された錠剤に吸湿させるための加湿工程と、上記加湿工程で加湿された錠剤を乾燥させる乾燥工程とを備えることを特徴とする速溶解性錠剤の製造方法が記載されている。
しかしながら、何れの製剤又は製造方法においても、成形された成型物を加湿する工程が必要であり、この加湿工程で錠剤がふやけて錠剤の外観が損なわれ、商品価値が低下するという課題がある。
特開平5−271054号公報には、薬効成分と糖類と上記糖類の粒子表面が湿る程度の水分を含む混合物を打錠する口腔内溶解型錠剤の製造方法が記載されているが、この製造方法は、打錠用の混合物に強制的に水分を添加し、湿った状態で打錠を行う湿式打錠法を用いたものであり、打錠障害により生産性が十分でないという課題を残している。これと同様に湿式打錠法に分類されるものとして、欧州特許出願公開EP0590963A1号記載の製造方法があるが、この製造方法では、湿式打錠時の打錠障害を解消するために、非常に特殊な製造機器を用いており、製造コスト及び生産性の問題を含んでいる。
また、国際公開WO95/34290号及び国際公開WO93/15724号公報記載の製造方法はともに湿式打錠法に分類されるが、特殊な賦形剤を使用しているか又は生産性が低いといった課題がある。
特公昭58−24410号公報には錠剤内容物を錠剤内容物に対して不活性な−30℃乃至+25℃で凍結する溶剤と混合し、この際、溶剤を全混合物の5乃至80重量%とし、混合物を不活性冷却媒体中に入れることにより固化させ、溶剤の凍結点より低い温度で圧縮して錠剤とし、さらに凍結乾燥又は自然乾燥により溶剤を揮発させて崩壊性の良好な多孔性錠剤を製造する方法が記載されている。また、特開平3−86837号公報には、水溶性、水和性のゲルあるいは泡沫物質からなる組成物から実質的に全ての水分が除去されるまで、約0℃又はそれ以下の温度で無水エタノールのような無水液体乾燥剤に接触させることによって得られる、十分な強度を備えた容易に溶解しうる担体物質が記載されている。
しかしながら、何れの製造方法も製造工程が複雑で、且つ凍結乾燥機等の製造設備が必要となりコストが高くなるという課題があった。
国際公開WO93/01805号と米国特許第5178578号明細書には、放出制御粒子を含む口腔内崩壊型製剤についての記載があるが、これは単なる混合物又は配合物を打錠するだけのことであるため、口腔内崩壊型製剤の特性である口腔内における速やかな崩壊性について検討の余地が残る。
また、特開平8−301751号公報には、未硬化剪断型マトリックスと放出制御型システムを混合し、成形・硬化する急速溶解性食用単位が記載されているが、未硬化剪断型マトリックスとして、具体的には非晶質化した糖類を使用しなければならず、かかる非晶質化処理が煩雑である。
特開平2−32014号公報には、経口投与に適した湿製錠剤の形態の固形製剤が記載されているが、スプレードライ工程、続いてエタノール/水又は水単独で湿潤塊を調製し、鋳型に入れ乾燥させて錠剤を得る方法であるため、製造工程が煩雑であり生産性が低いことが予想される。
また、特開昭61−15830号公報には、制酸剤と製菓用甘味料及び可塑剤を含む製菓用基材を含み、多孔性極微細結晶構造を有する制酸剤組成物が記載されているが、製造方法が煩雑であり生産性に課題がある。
発明の開示
本発明は、上述したような従来技術の有する課題に鑑みてなされたものであり、その目的とするところは、製剤の取扱いにおいて必要とされる適切な強度を有し、しかも口腔内において速やかに崩壊する口腔内崩壊型組成物及び口腔内崩壊型製剤を提供することにある。
また、本発明の他の目的は、上記のような優れた特性を持った口腔内崩壊型組成物及び口腔内崩壊型製剤を、複雑な工程及び特殊設備を要することなく、実質的に乾燥状態で打錠工程を行い、製造可能とすることにある。
本発明者らは、上記目的を達成すべく鋭意検討を重ねた結果、特定の賦形剤と崩壊剤を用い、これらの混合物又は造粒物に特定の滑沢剤を添加し、打錠することによって、予想外にも製造工程や保存及び流通過程で壊れない程度の適当な強度を有し、且つ口腔内での速やかな崩壊性を有する組成物が得られることを見出し、本発明を完成するに至った。
即ち、口腔内崩壊型組成物は、口腔内で速やかに崩壊する成型組成物であって、糖アルコールから成る賦形剤と、崩壊剤と、滑沢剤を含有して成り、この滑沢剤に対するエタノールの浸透速度が3.0×10−3/sec以上であることを特徴とする。
この場合、上記滑沢剤に対するエタノールの浸透速度が5.0×10−3/sec以上であることが望ましい。
また、本発明の口腔内崩壊型組成物の好適形態は、上記滑沢剤が、ロイシン及び/又はフマル酸ステアリルナトリウム、あるいはステアリン酸及び/又はタルクであることを特徴とする。
更に、本発明の口腔内崩壊型組成物の他の好適形態は、上記糖アルコールがマンニトール及び/又はエリスリトールであることを特徴とする。
更にまた、本発明の口腔内崩壊型組成物の更に他の好適形態は、上記崩壊剤が、低置換度ヒドロキシプロピルセルロース、結晶セルロース、ヒドロキシプロピルスターチ、カルボキシメチルスターチナトリウム、コムギデンプン、コメデンプン、トウモロコシデンプン及びバレイショデンプンから成る群より選ばれた少なくとも1種の難水溶性の結合性崩壊剤であるか、あるいはクロスカルメロースナトリウム、カルメロースカルシウム、クロスポビドン、水酸化アルミナマグネシウム、炭酸マグネシウム及びリン酸二水素カルシウムから成る群より選ばれた少なくとも1種のものであることを特徴とする。
また、本発明の口腔内崩壊型組成物の他の好適形態は、上記賦形剤を32〜99.2%、上記崩壊剤を0.5〜60%、上記滑沢剤を0.3〜8.0%の割合で配合して成ることを特徴とする。
更に、本発明の口腔内崩壊型組成物の更に他の好適形態は、錠剤強度が20N以上であることを特徴とし、また、健常成人での口腔内崩壊時間が90秒以内であることをが好ましい。
一方、本発明の口腔内崩壊型製剤は、上述の如き口腔内崩壊型組成物に、薬効成分を添加して成ることを特徴とし、この場合、上記薬効成分としては、中枢神経系用薬、末梢神経系用薬、感覚器官用薬、アレルギー用薬、循環器官用薬、呼吸器官用薬、消化器官用薬、ホルモン剤、泌尿生殖器官及び肛門用薬、ビタミン剤、滋養強壮変質剤、血液及び体液用薬、代謝性医薬品、細胞賦活用薬、腫瘍用薬、診断用薬、物理的障害用薬、抗生物質、化学療法剤、生物学的薬剤、生理活性ペプチド類又は寄生動物に対する薬、並びにこれらの任意の混合薬を用いることができる。
以下、本発明の口腔内崩壊型組成物及び口腔内崩壊型製剤について詳細に説明する。なお、本明細書において、「%」は特記しない限り質量百分率を表す。
上述の如く、本発明の口腔内崩壊型組成物は、代表的には、非多孔質の圧縮成型組成物であり、糖アルコールから成る賦形剤と、崩壊剤と、所定の滑沢剤を含有する。
ここで、賦形剤としては、水溶性で適度な甘味と冷涼感があるものが好ましく、各種糖アルコールを用いることができるが、特にマンニトール又はエリスリトール及びこれらの混合物を好適に使用することができ、特にマンニトールが望ましい。
また、崩壊剤としては、結合剤的性能をも併せ持つ難水溶性の結合性崩壊剤、例えばヒドロキシプロピルスターチ、低置換度ヒドロキシプロピルセルロース、結晶セルロース、カルボキシメチルスターチナトリウム、コムギデンプン、コメデンプン、トウモロコシデンプン又はバレイショデンプン及びこれらの任意の混合物を使用することができる。
かかる結合性崩壊剤によれば、結合剤又は崩壊剤を添加した錠剤よりも速崩性に優れ、しかも成型性が良好な錠剤が得られやすいという利点がある。但し、本発明においては、結合剤は必須成分ではない。
一方、本発明においては、結合剤的性能を有さない通常の崩壊剤、例えばクロスカルメロースナトリウム、カルメロースカルシウム、クロスポビドン、水酸化アルミナマグネシウム、炭酸マグネシウム又はリン酸二水素カルシウム及びこれらの任意の混合物も使用することができる。
更に、本発明で用いる所定の滑沢剤は、この崩壊型組成物が口腔内で崩壊する際、組成物内部への水の浸入を容易にする機能を有し、当該滑沢剤に対するエタノールの浸透速度が3.0×10−3/秒以上であるものが該当する。
具体的には、ロイシン、フマル酸ステアリルナトリウム、タルク及びステアリン酸等を挙げることができ、ロイシン及びフマル酸ステアリルナトリウムを好適に用いることができ、これらは単独で又は2種以上を混合して使用することが可能である。
なお、本発明においては、従来から頻用されているステアリン酸マグネシウムのような滑沢剤であってもエタノールの浸透速度が3.0×10−3/秒未満のもの自体の使用は望ましくなく、このような滑沢剤の使用は組成物や製剤の崩壊時間の延長を招く。
但し、本発明では、上述したエタノールの浸透速度を逸脱しない限りにおいて、他の滑沢剤、例えば、ステアリン酸マグネシウム、ステアリン酸カルシウム、ステアリルアルコール、水添植物油、マクロゴール、ショ糖脂肪酸エステル、軽質無水ケイ酸、ラウリル硫酸ナトリウム、安息香酸ナトリウム、含水二酸化ケイ素及びグリセリルベヘネートなどをロイシン等と併用することが可能であり、特にステアリン酸マグネシウム、ステアリン酸カルシウム、水添植物油、ショ糖脂肪酸エステル及び軽質無水ケイ酸を好ましく併用することができる。
更に、本発明においては、上記エタノールの浸透速度を満足するのであれば、一般に「滑沢剤」と称されているもののみならず、滑沢機能、即ち、
▲1▼「摩擦減少能」:粉体間又は粉体と打錠機の臼杵との摩擦を減少させ、錠剤の圧縮及び臼杵からの放出を容易にする機能、
▲2▼「流動性改善能」:粉体の流動性を改善する機能、及び
▲3▼「付着防止能」:粉体成形時に粉体が機器との接触面に付着するのを防止する機能、のいずれか又は組合せ、特に摩擦減少能を有する材料を滑沢剤と同様に用いることができる。
本発明の口腔内崩壊型組成物における上記各成分の配合比は、特に限定されるものではないが、後述する錠剤強度と口腔内崩壊時間を実現できるように処方することが好ましく、代表的には、上記賦形剤を32〜99.2%、上記崩壊剤を0.5〜60%、上記滑沢剤を0.3〜8.0%の割合で配合することが望ましい。
なお、上記結合性崩壊剤として、低置換度ヒドロキシプロピルセルロースを用いる場合、その配合量は10〜40%が適量であり、結晶セルロース又はヒドロキシプロピルスターチを用いる場合、その配合量は10〜60%が適量である。また、上記崩壊剤として、クロスカルメロースナトリウムを用いる場合、その配合量は0.5〜5%とすることが好ましい。クロスポビドンを用いる場合は、その配合量は2〜20%が適量である。
本発明の口腔内崩壊型組成物の必須成分は、上述した糖アルコールから成る賦形剤、結合性崩壊剤又は通常の崩壊剤、及び所定の滑沢剤であるが、後述する崩壊性その他の特性に悪影響を与えない限り、錠剤製造に一般に用いられる各種の添加剤を含有させることも可能である。
かかる添加剤としては、例えば、結合剤、甘味料、香料及び着色剤などが挙げられる。
結合剤としては、アラビアゴム、アルギン酸ナトリウム、ビニルピロリドン及びプルランなどが挙げられる。甘味料としては、アスパルテームやアセスルファムK等が挙げられ、香料としては、レモンライム、オレンジ及びメントール等が挙げられる。また、着色料としては、食用黄色5号、食用赤色5号、食用レーキ色素及び黄色三二酸化鉄等が挙げられる。
上述の添加剤は、単独で又は2種以上を組み合わせて使用することができ、更に、これらの添加剤は、後述する本組成物の製造工程の何れの段階においても添加することができる。
上述した本発明の口腔内崩壊型組成物は、優れた特性を有し、代表的には、錠剤強度が20N以上であり、健常成人での口腔内崩壊時間が通常90秒以内、好ましくは40秒以内、より好ましくは30秒以内であることが望ましい。
かかる特性の兼備により、本発明の組成物や製剤は、製剤の取扱い上必要な強度を有し、しかも口腔内において速やかに崩壊するという優れた性能を発揮する。
次に、本発明の口腔内崩壊型組成物の製造方法について説明する。
本発明の口腔内崩壊型組成物は、上述した賦形剤、結合性崩壊剤(又は通常の崩壊剤)及び所定の滑沢剤を混合した後に打錠する方法、混合してから乾式造粒した後に打錠する方法、又は賦形剤と結合性崩壊剤(又は通常の崩壊剤)を湿式造粒後に乾燥し、乾燥状態の造粒物と所定の滑沢剤を混合後に打錠する方法、の3種類の一般的な製造方法によって製造され、特別な製造装置を必要としない。
また、上記製造方法において、混合、造粒、乾燥及び打錠方法は、特に限定されるものではないが、打錠するための混合物又は造粒物を実質的に乾燥状態にすることを要する。
混合物又は造粒物が乾燥状態でない場合は、打錠時にスティッキングを起こし易くなる他、原料粉体を打錠する際に連続的且つ定量的に供給できないことがあり、好ましくない。
次に、本発明の口腔内崩壊型製剤について説明する。
本発明の口腔内崩壊型製剤は、上述した口腔内崩壊型組成物に薬効成分を加えたものであり、原則として、本発明の組成物と同等の特性を有する。
ここで、薬効成分としては、中枢神経系用薬、末梢神経系用薬、感覚器官用薬、アレルギー用薬、循環器官用薬、呼吸器官用薬、消化器官用薬、ホルモン剤、泌尿生殖器官及び肛門用薬、ビタミン剤、滋養強壮変質剤、血液及び体液用薬、代謝性医薬品、細胞賦活用薬、腫瘍用薬、診断用薬、物理的障害用薬、抗生物質、化学療法剤、生物学的薬剤、生理活性ペプチド類、寄生動物に対する薬などを挙げることができ、所要に応じて、これらの薬効成分の一種又は複数の成分を混合して用いることができる。
上記薬効成分の配合量は、その性質にもよるが、固形成分、即ち本発明の口腔内崩壊型組成物全体の80%以下、好ましくは0.03〜50%、更に好ましくは0.03〜20%とすることが望ましい。
薬効成分の配合量が80%を超えると、最終製品の口腔内崩壊性と錠剤強度との良好なバランスが得られず、好ましくない。
なお、本発明の製剤は、固形製剤、代表的には錠剤形態を採るが、従来公知の手法により、苦味マスキング等のマスキングを施すことができる。
かかるマスキングは、薬効成分の原末や顆粒に施し、これを打錠することによって行える。
本発明の製剤は、上述した本発明の組成物の製造方法と同様にして製造できるが、この際、薬効成分の添加は上記打錠前までに行えばよい。
発明を実施するための最良の形態
以下、本発明を実施例及び比較例により更に詳細に説明するが、本発明はこれら実施例に限定されるものではない。なお、各例で得られた組成物や製剤につき、下記の性能評価を行った。
また、実施例において、ヒドロキシプロピルスターチにはHPS−101(フロイント産業(株)製商品名)を、結晶セルロースにはアビセルPH−102(旭化成工業(株)製商品名)を、低置換度ヒドロキシプロピルセルロースにはL−HPC(LH−21)(信越化学工業(株)製商品名)を使用した。
[錠剤強度]
錠剤硬度計(Schleuniger社製,型式:6D)を用いて測定した。測定は5回行い、その平均値を示した。
[口腔内崩壊時間]
健康な成人男子の口腔内で唾液により、錠剤が完全に崩壊するまでの時間を測定した。測定は実施例1〜3については5人、実施例4〜18については3人、実施例19〜26及び比較例1〜6については4人を被験者として行い、その平均値を示した。
[エタノールの浸透速度]
計測には自動表面張力計(KRUSS GmbH社製、type;K121)を用いた。対象とする滑沢剤サンプルを内径1.2cmのサンプルホルダーに測定に必要な十分量を充填する。その後、ホルダー内のサンプルをシリンダーにより荷重200gで10秒間圧縮して測定に供する。
浸透溶媒にはエタノールを用いた。測定は3回行い、その平均曲線について浸透速度を算出した。
液体の粉体に対する浸透速度は、Washburnの式(Washburn,E.W.:Phys.Rev.,27273(1921))において、L/t(Lは粉体層への液面の浸透距離、tは時間を示す)と表されるが、ここでは、液体の浸透距離Lの代わりに浸透した液体の重量増加Wに置き換えたW/t[g/sec]を浸透速度とした。
[各種滑沢剤に対するエタノールの浸透速度]

表20より、本発明の範囲に属する実施例4〜18によれば、製造時及び流通時の衝撃に十分耐え、且つ速やかに口腔内にて崩壊する錠剤が得られることが分かる。なお、現時点では、低い成型圧力で高い硬度が得られ、口腔内崩壊時間が短いという観点から、実施例7及び10が最も良好であるといい得る。
(実施例19〜24、比較例1〜3)
目開き840μm(20メッシュ)の篩を通過させた60gのマンニトール粉末と、40gのヒドロキシプロピルスターチ粉末を乳鉢で約5分間混合した。得られた混合物100gに対して15mlの精製水を添加し、約5分間混合して造粒した後、目開き1700μm(10メッシュ)の篩を通し、60℃で3時間乾燥した。この乾燥混合物を600μm目開きの篩を介して整粒し、顆粒を得た。 得られた顆粒に対し、フマル酸ステアリルナトリウム(SSF)又はステアリン酸マグネシウム(Mg−St)を表21に示す割合で添加し、即ち実施例19、21及び23、比較例1〜3では、上記顆粒29.7gに対してSSF又はMg−Stを300mg添加し、実施例20、22及び24では上記顆粒29.4gに対してSSFを600mg添加した。

表21及び図4より、SSFを使用した実施例19〜24では、Mg−Stを使用した比較例1〜3よりも、錠剤の口腔内崩壊時間が約10秒短縮されていることが分かる。なお、各例の錠剤硬度を揃えたことから、かかる差異はSSFの添加に起因するものと考えられる。
また、滑沢化における回転数が増大するほど、即ち滑沢剤が顆粒に十分に混合されるにつれて、Mg−Stでは高い打錠圧を必要とし、口腔内崩壊時間も長くなる傾向にあるが、SSFはこのような傾向を示さず、安定した効果を発現することも分かる。

Patient preferences were also investigated for easy-to-use dosage forms, future desired dosage forms, and taste preferences for internal medicines.
This research report pointed out that the elderly have many problems in terms of dosage form when taking medicines. As a result, many of the currently used dosage forms are for general adults. As a result, it has become desirable to develop a dosage form that can be easily taken even by the physically handicapped elderly who need assistance, and that is easy to take even for elderly people who refuse to take because of difficulty. It was. In addition, a dosage form that can be easily taken even by elderly people is preferable for children and general adults.
Furthermore, according to this research report, orally disintegrating preparations, paste-like preparations and jelly-like preparations have been proposed as new preparations preferable for elderly people. Considering stability and the like, it is considered to be the most realistic preparation, and from this viewpoint, this type of preparation is being studied and developed.

However, since such a preparation is prepared by lyophilization, a production facility for lyophilization is required, resulting in high costs. Moreover, since the preparation obtained by freeze-drying has low strength, there is a problem that it is generally inconvenient to handle.
In addition, International Publication No. WO 93/12769 discloses a density of 400 mg / ml to 1000 mg of an active ingredient and a sugar comprising lactose and / or mannitol and a solid component containing 0.12 to 1.2 w / w% agar. Orally disintegrating solid preparations having sufficient strength for handling the preparations are described.

In order to obtain a possible hardness, a tableting step for press molding at the minimum necessary low pressure, a humidification step for absorbing moisture in the tablet formed in the tableting step, and a tablet humidified in the humidification step A method for producing a fast-dissolving tablet comprising a drying step for drying is described.
However, in any preparation or manufacturing method, a step of humidifying the molded product is necessary, and there is a problem that the tablet is swollen in this humidification step, the appearance of the tablet is impaired, and the commercial value is lowered.
Japanese Patent Application Laid-Open No. 5-270544 describes a method for producing an orally-dissolving tablet for tableting a mixture containing a medicinal ingredient, a saccharide, and water containing such a degree that the particle surface of the saccharide is moistened. The method uses a wet tableting method in which moisture is forcibly added to a tableting mixture and tableting is performed in a wet state, leaving the problem that productivity is not sufficient due to tableting failure. Yes. Similarly to this, there is a manufacturing method described in European Patent Application Publication No. EP 0590963A1 as classified as a wet tableting method. However, in this manufacturing method, in order to eliminate the tableting trouble at the time of wet tableting, Special manufacturing equipment is used, which includes manufacturing cost and productivity problems.

The mixture is solidified by placing it in an inert cooling medium, compressed into a tablet at a temperature lower than the freezing point of the solvent, and then the solvent is volatilized by freeze-drying or natural drying to form a porous tablet with good disintegration. A method of manufacturing is described. JP-A-3-86837 discloses an anhydrous solution at a temperature of about 0 ° C. or lower until substantially all moisture is removed from a composition comprising a water-soluble, hydratable gel or foam substance. An easily soluble carrier material with sufficient strength obtained by contact with an anhydrous liquid desiccant such as ethanol is described.
However, any of the manufacturing methods has a problem that the manufacturing process is complicated, and manufacturing equipment such as a freeze dryer is required, resulting in an increase in cost.
International Publication No. WO 93/01805 and US Pat. No. 5,178,578 describe an orally disintegrating formulation containing controlled release particles, which simply compresses the mixture or formulation. Therefore, there remains room for studying the rapid disintegration property in the oral cavity, which is a characteristic of the orally disintegrating preparation.

On the other hand, in the present invention, conventional disintegrants that do not have binder-like performance, such as croscarmellose sodium, carmellose calcium, crospovidone, magnesium alumina hydroxide, magnesium carbonate or calcium dihydrogen phosphate, and any of these A mixture of these can also be used.
Furthermore, the predetermined lubricant used in the present invention has a function of facilitating the entry of water into the composition when the disintegrating composition disintegrates in the oral cavity. The permeation rate is 3.0 × 10 −3 g 2 / sec or more.
Specific examples include leucine, sodium stearyl fumarate, talc and stearic acid, and leucine and sodium stearyl fumarate can be suitably used. These can be used alone or in admixture of two or more. Is possible.
In the present invention, it is desirable to use a lubricant having a penetration rate of ethanol of less than 3.0 × 10 −3 g 2 / sec, even if it is a lubricant such as magnesium stearate that has been frequently used in the past. In addition, the use of such a lubricant leads to an extended disintegration time of the composition or formulation.
However, in the present invention, other lubricants, for example, magnesium stearate, calcium stearate, stearyl alcohol, hydrogenated vegetable oil, macrogol, sucrose fatty acid ester, light anhydrous, as long as they do not deviate from the above-mentioned ethanol penetration rate. Silicic acid, sodium lauryl sulfate, sodium benzoate, hydrous silicon dioxide and glyceryl behenate can be used in combination with leucine, etc., especially magnesium stearate, calcium stearate, hydrogenated vegetable oil, sucrose fatty acid ester and light Silicic anhydride can be preferably used in combination.
Furthermore, in the present invention, as long as the ethanol penetration rate is satisfied, not only what is generally called a “lubricant”, but also a lubricating function,
(1) “Friction reducing ability”: a function that reduces the friction between powders or between the powder and the mortar of the tableting machine, and facilitates the compression and release of the tablet from the mortar,
(2) “Fluidity improving ability”: function to improve the fluidity of the powder, and (3) “Adhesion prevention ability”: function to prevent the powder from adhering to the contact surface with the equipment during powder molding. , Or a combination thereof, in particular, a material having a friction reducing ability can be used in the same manner as the lubricant.
The blending ratio of each of the above components in the orally disintegrating composition of the present invention is not particularly limited, but it is preferably formulated so that the tablet strength and the orally disintegrating time described below can be realized. It is desirable to blend 32 to 99.2% of the excipient, 0.5 to 60% of the disintegrant, and 0.3 to 8.0% of the lubricant.
In addition, when low substituted hydroxypropyl cellulose is used as the binding disintegrant, the blending amount is 10 to 40%, and when crystalline cellulose or hydroxypropyl starch is used, the blending amount is 10 to 60%. Is the right amount. Moreover, when using croscarmellose sodium as said disintegrating agent, it is preferable that the compounding quantity shall be 0.5 to 5%. When crospovidone is used, the blending amount is 2 to 20%.
The essential components of the orally disintegrating composition of the present invention are the above-mentioned excipients composed of sugar alcohols, binding disintegrants or ordinary disintegrants, and predetermined lubricants. Various additives generally used in tablet production can be included as long as the properties are not adversely affected.
Examples of such additives include binders, sweeteners, fragrances, and coloring agents.
Examples of the binder include gum arabic, sodium alginate, vinyl pyrrolidone and pullulan. Examples of the sweetener include aspartame and acesulfame K, and examples of the flavor include lemon lime, orange and menthol. Examples of the colorant include edible yellow No. 5, edible red No. 5, edible lake pigment, and yellow iron sesquioxide.
The above-mentioned additives can be used alone or in combination of two or more, and these additives can be added at any stage of the production process of the composition described later.
The above-mentioned orally disintegrating composition of the present invention has excellent characteristics, typically has a tablet strength of 20 N or more, and the disintegration time in the normal adult is usually within 90 seconds, preferably 40. It is desirable to be within seconds, more preferably within 30 seconds.
Due to the combination of such properties, the composition or preparation of the present invention has the strength required for handling the preparation and exhibits excellent performance of rapidly disintegrating in the oral cavity.
Next, the manufacturing method of the orally disintegrating composition of this invention is demonstrated.
The orally disintegrating composition of the present invention is a method of tableting after mixing the above-described excipient, binding disintegrant (or ordinary disintegrant) and a predetermined lubricant, and dry granulation after mixing. Or tableting after mixing the excipient and the binding disintegrant (or ordinary disintegrant) after wet granulation, and mixing the granulated product in a dry state with a predetermined lubricant. These are manufactured by three general manufacturing methods, and no special manufacturing equipment is required.
Moreover, in the said manufacturing method, although mixing, granulation, drying, and a tableting method are not specifically limited, It is required to make the mixture or granulated material for tableting into a substantially dry state.
If the mixture or granulated product is not in a dry state, sticking tends to occur during tableting, and it may not be possible to continuously and quantitatively supply the raw material powder when tableting.
Next, the orally disintegrating preparation of the present invention will be described.
The orally disintegrating preparation of the present invention is obtained by adding a medicinal component to the orally disintegrating composition described above, and in principle has the same characteristics as the composition of the present invention.
Here, the medicinal ingredients include central nervous system drugs, peripheral nervous system drugs, sensory organ drugs, allergy drugs, cardiovascular drugs, respiratory organ drugs, digestive organ drugs, hormone drugs, urogenital organs And anal drugs, vitamins, nourishing tonics, blood and body fluids, metabolic drugs, cell stimulants, tumor drugs, diagnostic drugs, physical disorder drugs, antibiotics, chemotherapeutic drugs, biological Examples include pharmacological drugs, physiologically active peptides, drugs for parasitic animals, and the like, and one or more of these medicinal ingredients can be mixed and used as necessary.
The compounding amount of the above-mentioned medicinal component depends on its properties, but it is 80% or less, preferably 0.03 to 50%, more preferably 0.03 to the solid component, that is, the whole orally disintegrating composition of the invention. 20% is desirable.
When the compounding amount of the medicinal component exceeds 80%, a good balance between the oral disintegration property of the final product and the tablet strength cannot be obtained, which is not preferable.
In addition, although the formulation of this invention takes a solid formulation, typically a tablet form, masking, such as bitterness masking, can be performed by a conventionally well-known method.
Such masking can be performed by applying the active ingredient to the powder or granule and compressing it.
The preparation of the present invention can be produced in the same manner as the above-described method for producing the composition of the present invention. At this time, the medicinal component may be added before the tableting.
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples, but the present invention is not limited to these Examples. In addition, the following performance evaluation was performed about the composition and formulation obtained in each case.
In Examples, HPS-101 (trade name, manufactured by Freund Sangyo Co., Ltd.) is used for hydroxypropyl starch, and Avicel PH-102 (trade name, manufactured by Asahi Kasei Kogyo Co., Ltd.) is used for crystalline cellulose. L-HPC (LH-21) (trade name, manufactured by Shin-Etsu Chemical Co., Ltd.) was used for propylcellulose.
[Tablet strength]
It was measured using a tablet hardness meter (manufactured by Schleuniger, model: 6D). The measurement was performed 5 times and the average value was shown.
[Oral disintegration time]
The time until the tablet completely disintegrated with saliva in the mouth of a healthy adult male was measured. The measurement was carried out using 5 persons for Examples 1 to 3, 3 persons for Examples 4 to 18, and 4 persons for Examples 19 to 26 and Comparative Examples 1 to 6, and the average values were shown.
[Penetration rate of ethanol]
An automatic surface tension meter (manufactured by KRUSS GmbH, type; K121) was used for the measurement. A sufficient amount of the lubricant sample to be measured is filled in a sample holder having an inner diameter of 1.2 cm. Thereafter, the sample in the holder is compressed by a cylinder with a load of 200 g for 10 seconds and used for measurement.
Ethanol was used as the osmotic solvent. The measurement was performed three times, and the permeation rate was calculated for the average curve.
The permeation rate of the liquid into the powder is L 2 / t (L is the permeation distance of the liquid surface into the powder layer) in the equation of Washburn (Washburn, EW: Phys. Rev., 27 273 (1921)). , T indicates time), but here, W 2 / t [g 2 / sec] replaced with the weight increase W of the permeated liquid instead of the permeation distance L of the liquid was defined as the permeation rate.
[Penetration rate of ethanol into various lubricants]
About seven types of lubricants, the penetration rate of ethanol was measured by the above-mentioned method. The obtained results are shown in Table 1. Since sucrose fatty acid ester and stearic acid were dissolved in ethanol, ethanol previously saturated with sucrose fatty acid ester and stearic acid was used as the permeation solution.

Next, this granule was filled into a container with a lid, and this container was subjected to 50 rotations with a turbuler shaker (Willy A. Bachofen AG Machinenfabrik type: T2C), and lubrication was performed by applying the lubricant to the granule. .
Thereafter, as shown in Table 2, the lubricated granules were compressed using a hydraulic press at a pressure such that the tablet hardness was about 20-30 N, and formed into tablets. The tablet shape is a corner flat tablet having a diameter of 7.94 mm and a weight of 200 mg. The obtained tablets were subjected to the performance evaluation described above, and the results are shown in Table 2. In addition, the thing using stearic acid Mg, stearic acid Ca, or sucrose fatty acid ester as a lubricant corresponds to the formulation outside the scope of the present invention.

The dried mixture was sized through a sieve having an opening of 600 μm (28 mesh) to obtain granules.
Thereafter, tablets were prepared and evaluated for performance in the same manner as in Example 1. However, compression molding was performed so that the tablet hardness was about 30 to 40N. The results are shown in Table 4. In addition, the thing using stearic acid Mg, stearic acid Ca, or sucrose fatty acid ester as a lubricant corresponds to the formulation outside the scope of the present invention.

Figure 0004802436
From Table 20, it can be seen that according to Examples 4 to 18 belonging to the scope of the present invention, tablets that can sufficiently withstand impact during production and distribution and rapidly disintegrate in the oral cavity can be obtained. In addition, at present, it can be said that Examples 7 and 10 are the best from the viewpoint that a high hardness is obtained with a low molding pressure and the disintegration time in the oral cavity is short.
(Examples 19 to 24, Comparative Examples 1 to 3)
60 g of mannitol powder passed through a sieve having an opening of 840 μm (20 mesh) and 40 g of hydroxypropyl starch powder were mixed in a mortar for about 5 minutes. 15 ml of purified water was added to 100 g of the obtained mixture, mixed for about 5 minutes and granulated, passed through a sieve having an opening of 1700 μm (10 mesh), and dried at 60 ° C. for 3 hours. The dried mixture was sized through a sieve having an opening of 600 μm to obtain granules. To the obtained granules, sodium stearyl fumarate (SSF) or magnesium stearate (Mg-St) was added in the ratio shown in Table 21, that is, in Examples 19, 21 and 23, and Comparative Examples 1 to 3, 300 mg of SSF or Mg-St was added to 29.7 g of granules, and in Examples 20, 22 and 24, 600 mg of SSF was added to 29.4 g of the granules.
Next, the granules are filled into a container with a lid, and the container is turned upside down (1) 10 times (rotation method in which the lid and the bottom are reversed), (2) 10 times upside down with inclination, and (3) 10 times. Then, it was subjected to a rotation process in which the inverted rotation was set as one set, and SSF or Mg-St, which is a lubricant, was blended into the granules to be lubricated. In this case, the total number of revolutions is 30 × N (the number of sets). Table 21 shows the number of rotations in each example.
Thereafter, as shown in Table 21, the lubricated granules were compressed at a pressure such that the tablet hardness was about 40 N and molded into tablets. The tablet shape is the same as in Example 4.
The above-mentioned performance evaluation was performed on the obtained tablets, and the results obtained are shown in Table 21 and shown in FIG.
Figure 0004802436
From Table 21 and FIG. 4, in Examples 19-24 using SSF, it turns out that the oral disintegration time of a tablet is shortened by about 10 second compared with Comparative Examples 1-3 using Mg-St. In addition, since the tablet hardness of each example was prepared, it is thought that this difference originates in addition of SSF.
In addition, as the number of rotations in lubrication increases, that is, as the lubricant is sufficiently mixed with the granules, Mg-St requires a higher tableting pressure, and the oral disintegration time tends to be longer. It can also be seen that SSF does not show such a tendency and exhibits a stable effect.
(Comparative Example 4)
49.0 g of erythritol is sieved with a sieve having an opening of 840 μm (# 20), and 0.5 g of a water-soluble binder, polyvinylpyrrolidone K25, dissolved in 2.5 ml of purified water is added thereto. Done the grain.
Next, the granulated product is sieved with a sieve having an opening of 1700 μm (# 10), dried at 60 ° C. for 3 hours, and then sieved with a sieve having an opening of 600 μm (# 28) to adjust the size of the granules Got.
SSF was added to this granule at a ratio of 1%, and as described above, using a container with a lid, (1) 40 inverted rotations, (2) 40 inverted rotations with inclination, (3) 40 The tablet shape is the same as in Example 4, after subjecting it to rotation processing with one set of inverted rotations, blending the SSF into the granules, smoothing, and then press molding with the tableting pressure shown in Table 22. A tablet of this example having
The obtained tablets were subjected to the same performance evaluation as described above, and the results obtained are also shown in Table 22.
(Comparative Example 5)
The same operation as in Comparative Example 4 was performed to obtain a smoothed granule. The granules were then tableted at 79 MPa (400 kgf) pressure, then humidified for about 5 minutes under the conditions of 40 ° C. and relative humidity 75% RH, and further dried for 5 minutes. A tablet of this example having
The obtained tablets were subjected to the same performance evaluation as described above, and the results obtained are also shown in Table 22.
(Comparative Example 6)
Except for using 1.0 g of polyvinylpyrrolidone K25, the same operation as in Comparative Example 4 was repeated to obtain a tablet of this example. The obtained tablets were subjected to the same performance evaluation as described above, and the results obtained are also shown in Table 22.
Figure 0004802436
From Table 22, in Comparative Examples 4 and 6, tablet hardness was extremely small, and only tablets that could not withstand normal use were obtained (usually a tablet hardness of about 20 N is required).
In addition, according to Comparative Example 5, although an orally disintegrating tablet having good characteristics was obtained, it was necessary to apply a special manufacturing method requiring low-pressure tableting and humidification / drying of the tablet. Remained. Moreover, since the compounding prescription of the comparative example 4 and the comparative example 5 is the same, if a normal manufacturing method is applied, depending on the prescription of the comparative example 5, the orally disintegrating tablet which has a favorable characteristic will be obtained. It is clear that this is not possible.
(Example 25)
The same operation as in Example 4 was repeated. However, L-leucine and magnesium stearate were used as lubricants instead of sodium stearyl fumarate. The blending ratio was in accordance with Table 23, and tablets were molded at a pressure of 178 MPa.
