Abstract
Description
一方、特許文献1や特許文献2に開示される有核型錠剤においては、新たな錠剤の技術として興味深いところであり、特に特許文献2においてはマイクロカプセル様顆粒を内核に適用した製造例が開示されており、口腔内崩壊錠等の更なる機能性製剤への応用が期待されていた。しかしながら、実際特許文献2で開示された製剤と同様の外層を有した有核型錠剤を作製したところ、口腔内での崩壊性が著しく悪く(本発明の比較例1-3参照)、また、有核型速崩壊錠とされている特許文献1に開示されている外層を用い、成形性のない粒子を含む有核錠を作製したところ、十分な硬度が得られないことがわかった(本発明の比較例1-4参照)。
このように、内核と外層の二重構造を有する有核型錠剤、特に内核に成形性のない粒子を用いる場合は、実質的にその外層のみで錠剤の硬度を維持する必要があり、通常の錠剤よりも強固な硬度への工夫が要求される一方、口腔内崩壊錠に適用させる場合には、満足な速崩壊性を得るためにその硬度の低下は避けられず、有核型錠剤として要求される強固な硬度を維持することは難しい状況にあった。
本発明の目的は、内核が成形性の低い粉粒体であることを特徴とする有核成型品を新たに開発することであり、錠剤全体として優れた崩壊性及び適切な硬度を有する有核型の口腔内崩壊錠を提供することにある。
[項2]内核が、成形性の低い粉粒体である項1に記載の有核型の口腔内崩壊錠。
[項3]外層部分100重量%における結晶セルロース(a)の配合割合が、5~80重量%である項1又は2に記載の有核型の口腔内崩壊錠。
[項4]外層部分100重量%における無機賦形剤(b)の配合割合が、10~80重量%である項1~3のいずれか一項に記載の有核型の口腔内崩壊錠。
[項5]外層部分100重量%における配合する特定成分(c)の合計の配合割合が、1~40重量%である項1~4のいずれか一項に記載の有核型の口腔内崩壊錠。
[項6]特定成分(c)が、クロスポビドン、デンプン類及び低置換度ヒドロキシプロピルセルロースからなる群から選択される1種又は2種以上である項1~5のいずれか一項に記載の有核型の口腔内崩壊錠。
[項7]デンプン類が、トウモロコシデンプンである項1~6のいずれか一項に記載の有核型の口腔内崩壊錠。

[項9]外層部分の空隙率が1~40%である項1~8のいずれか一項に記載の有核型の口腔内崩壊錠。
[項10]内核に活性成分が含まれる項1~9のいずれか一項に記載の有核型の口腔内崩壊錠。
[項11]外層部分100重量%における結晶セルロース(a)の配合割合が、10~70重量%である項1~10のいずれか一項に記載の有核型の口腔内崩壊錠。
[項12]内核が、マイクロカプセル様の機能性粒子以外の、成形性の低い粉末、造粒物、または粉粒体である項1~11のいずれか一項に記載の有核型の口腔内崩壊錠。
また本発明においては、内核成分として、マイクロカプセル様の機能性粒子以外の、成形性の低い粉末、造粒物、粉粒体等についても実施可能であり、十分な硬度と崩壊性を有する有核型の口腔内崩壊錠が提供される。
絶対硬度(N/mm2)=硬度(N)/断面積(mm2)
HDBI(N/mm2・秒)=絶対硬度(N/mm2)÷口腔内崩壊時間(秒)
成形性がない内核を有する有核型の口腔内崩壊錠においては、硬度及び崩壊性は外層処方にのみ依存し、単層の口腔内崩壊錠(普通錠の口腔内崩壊錠)及び成形性のある内核を有する有核型の口腔内崩壊錠に比べて、硬度と崩壊性のバランスを両立させることは困難である。たとえ、硬度と崩壊性のバランスを両立させたとしても、打錠圧の許容幅を広く確保することは極めて困難であった。

ρ:錠剤の真密度(mg/mm3)、V:錠剤の体積(mm3)、Wt:錠剤重量(mg)
本発明において、外層部分の空隙率は、以下の式により求められる。
外層部分の空隙率(%)=(1-Wt/(ρ×3.14×D2×T))×100
ρ:外層の真密度(mg/mm3)、D:外層(下)の半径(mm)、T:外層(下)の厚み(mm)、Wt:外層(下)の重量(mg)
内核の厚み(mm)=錠剤全体の厚み(mm)-上下の外層の厚みの合計(mm)
本発明において「内核の厚みの割合」とは、錠剤全体の厚みに対する内核が占める厚みの割合を意味する。つまり、錠剤の側面に対して平行な断面において、内核が占める厚みの割合を意味する。切断部位によって内核が占める厚みの割合が異なる場合は、全ての断面において最も割合が大きい値を「内核の厚みの割合」と定義する。
内核の厚みの割合(%)=内核の厚み(mm)÷錠剤全体の厚み(mm)×100

本発明の外層の必須成分である特定成分は、クロスポビドン、デンプン類、低置換度ヒドロキシプロピルセルロース及びカルメロースからなる群から選択される少なくとも1種であることを特徴とする。有核型の口腔内崩壊錠の場合、内核を含有しない通常の錠剤と比較して、外層部分の空隙率を小さくして硬度を高める必要があるため、後述の特定成分を含まない場合や特定成分以外の崩壊性を高める成分を含有する場合には、所望の効果が得られない。それに対して、これら特定成分を結晶セルロース及び無機賦形剤とともに含有する場合に、所望の効果が得られることを見出したものである。
本発明に用いることができるクロスポビドンは、特に限定されないが、通常、日本薬局方に適合しているものが用いられる。その平均粒子径としては特に限定されないが、用いるクロスポビドンの平均粒子径が大きいと口腔内で崩壊した後に、ザラツキを感じるため、服用感の観点において原料とするクロスポビドンの平均粒子径は好ましくは10~200μm、より好ましくは10~150μm、さらに好ましくは10~100μmである。所望の粒子径とするため、必要に応じて適宜粉砕してもよい。粉砕方法としては例えば気流粉砕機やハンマー式粉砕機による方法が挙げられる。クロスポビドンの外層中の配合量は、硬度、崩壊時間及び打錠圧の許容幅の観点から、外層部分100重量%あたり、通常1~40重量%、好ましくは1~30重量%であるが、より好ましくは1~20重量%、さらに好ましくは1~10重量%、最も好ましくは1~5重量%である。

本発明に用いることができるカルメロースは、特に限定されないが、日本薬局方に適合しているものが用いられる。その平均粒子径としては特に限定されないが、用いるカルメロースの平均粒子径が大きいと口腔内で崩壊した後に、ザラツキを感じるため、服用感の観点において原料とするカルメロースの平均粒子径は好ましくは10~200μm、より好ましくは10~150μm、さらに好ましくは10~100μmである。所望の粒子径とするため、必要に応じて適宜粉砕してもよい。粉砕方法としては例えば気流粉砕機やハンマー式粉砕機によるものが挙げられる。カルメロースの配合量は、硬度、崩壊時間及び打錠圧の許容幅の観点から、外層部分100重量%あたり1~40重量%、好ましくは1~30重量%、より好ましくは1~20重量%であるが、さらに好ましくは1~10重量%、最も好ましくは1~5重量%である。
本発明の口腔内崩壊錠の外層には、上記の成分以外にもその他の製剤化成分を加えて製剤化することができる。本発明で用いられる「その他の製剤化成分」としては、配合しても薬剤の硬度及び崩壊時間に影響が無いか極めて少なく、製剤化するのに支障の無い成分であればいずれでもよい。例えば、他の賦形剤、崩壊剤、結合剤、甘味剤、矯味剤・矯臭剤、安定化剤、界面活性剤、流動化剤、帯電防止剤、コーティング剤、滑沢剤、着色剤、香料等がその例として挙げられる。「その他の製剤化成分」の配合量は、外層部分100重量%あたり0.01~25重量%であり、錠剤中にこれら製剤化成分を含むときは配合量に応じて上記の成分の量が減じられる配合割合でもって構成される。
本発明において、上記のその他の製剤化成分の中でも外層に滑沢剤を添加することが好ましい。滑沢剤としては、例えば、ステアリン酸、ステアリン酸金属塩、フマル酸ステアリルナトリウム、ショ糖脂肪酸エステル、タルク、硬化油、マクロゴール等が挙げられる。ステアリン酸金属塩としては、ステアリン酸マグネシウム、ステアリン酸カルシウム、ステアリン酸アルミニウム等が挙げられるが、滑沢剤の中でステアリン酸又はステアリン酸金属塩、特に、ステアリン酸マグネシウムが好ましい。滑沢剤を製剤化する前の平均粒子径は、0.5~50μmであり、好ましくは1~30μmである。滑沢剤の配合割合は、外層部分100重量%あたり通常0.01~2.5重量%であり、好ましくは0.01~2重量%である。さらに好ましくは0.01~1重量%である。本発明において該滑沢剤は、外部滑沢法及び内部滑沢法のいずれの方法を用いて配合してもよい。
本発明において、内核は口腔内崩壊性又は分散性が良好であれば特に限定されない。本発明の外層成分は、内核の成形性が低い場合にも、錠剤全体として十分な硬度を付与できることから、内核が「成形性の低い粉粒体」の場合、本発明の特徴を発揮できる。「成形性の低い粉粒体」とは、成形性の低い粉末、造粒物等を含む粉粒体を意味し、圧縮成形した際に成形物が得られないか、若しくは成形物が得られたとしても硬度が極めて低いことを意図する。具体的には、直径6mm、重量50mgを4kNで打錠した場合に、全く成形物が得られないか、若しくは成形物が得られたとしても極めて脆弱であり、硬度が10N以下の場合をいう。本発明に用いられる「成形性の低い粉粒体」の大きさは特に限定されないが、平均粒子径は通常3mm以下、口腔内での服用性の観点から、好ましくは1mm以下、さらに好ましくは300μm以下、最も好ましくは150μm以下である。本発明において、内核に活性成分を含めることが好ましく、例えば活性成分を含む微小カプセル又は被覆顆粒の機能性粒子、活性成分粉末自身、或いは活性成分を含む微小カプセル、被覆顆粒の機能性粒子又は活性成分粉末に流動性・分散性・付着性を改善する添加剤を加えた混合末、造粒物が含まれる。
ここで造粒物は、流動層造粒法、押出し造粒法、乾式圧密造粒法、転動造粒法、転動流動層造粒法、高速攪拌造粒法、破砕造粒法などにより調製することができる。

<有核型の口腔内崩壊錠の製造>
表1-1に示す処方にて、外層に異なる各特定成分を含む4種類の製剤を製造した。まず、外層の各成分を混合した。これを40mgとり、直径6mmの臼に入れ軽く振動させて粉末の表面を平滑化した(外層(下))。その上に、内核成分として結晶セルロース粒(セルフィアCP-203)を50mg加えて、ハンドプレス機(理研製、油圧式プレス機)を用いて、3kNの低い圧力で仮圧縮した。この仮圧縮物を外層(下)が下方になるように直径8mm杵に同心円状に配置し、直径8mmの臼を被せて、仮圧縮物の上から上記外層成分の混合物140mg(外層(側面+上))を入れて最終成形し、有核型の口腔内崩壊錠を製造した。最終成型物は10kNで打錠した。なお、本製剤に使用した結晶セルロース粒(セルフィアCP-203)50mgを、別途直径6mmの杵臼に入れて、打錠圧4kNで圧縮して得られた圧縮成形物の硬度は10N未満であった。
表2-1に示す処方にて、外層に特定成分を含まない製剤(比較例1-1)と特定成分の代わりに、クロスカルメロースNaを用いた製剤(比較例1-2)を、実施例1-1と同様の方法で製造した。なお、クロスカルメロースNaは、Ac-Di-Sol(五協産業社製)を用いた。
表2-4に示す特許文献2の製造例と類似する処方にて、外層に本発明の特定成分等を含まない製剤を実施例1-1と同様の方法で製造した。ただし、杵臼は少量のステアリン酸マグネシウムを塗布したものを使用した。Cellactose 80はMEGGLE社製を使用した。
表2-7に示す処方にて、外層に特定成分を含まない製剤を実施例1-1と同様の方法で製造した。外層処方は、特許文献1の試験例6(エリスリトール60mg、結晶セルロース19.5mg、ステアリン酸マグネシウム0.5mg)と同一の配合割合とした。
つまり、特許文献1で開示される外層成分は、成形性のない粒子を内核とした有核錠を作製した場合に、錠剤全体として十分な硬度を付与することができないことがわかった。
表3-1に示す処方にて、外層の結晶セルロース量が異なる5種類の製剤を実施例1-1と同様の方法で製造した。最終成型物は、実施例2-2は8kN、実施例2-4は15kN、その他は10kNで打錠した。
実施例2-1~2-5のように、外層の結晶セルロース量が5~80%の場合、口腔内崩壊時間は30秒以内、絶対硬度が1.5N/mm2以上を満たしており、硬度と崩壊性のバランスの指標であるHDBIが大きかった。
表3-4に示す処方にて、外層の結晶セルロース量が59.2%、無機賦形剤が30%の製剤を実施例1-1と同様の方法で製造した。最終成型物は10kNで打錠した。
口腔内崩壊時間は30秒以内、絶対硬度が1.5N/mm2以上を満たしており、硬度と崩壊性のバランスの指標であるHDBIが大きかった。
比較例1-1で示したとおり、外層にコーンスターチを全く含まない場合、口腔内で30秒以内に崩壊しなかったのに対して、実施例4-1~4-4のように、外層のコーンスターチの量が1~40%の場合、口腔内崩壊時間は30秒以内、絶対硬度が1.5N/mm2以上を満たしており、硬度と崩壊性のバランスの指標であるHDBIが大きかった。以上の結果から、外層のコーンスターチ量は1~40%のとき、良好な有核型の口腔内崩壊錠が得られることがわかった。
比較例1-1で示したとおり、外層にクロスポビドンを全く含まない場合、口腔内で30秒以内に崩壊しなかったのに対して、実施例5-1~5-4のように、外層のクロスポビドンの量が1~30%の場合、口腔内崩壊時間は30秒以内、絶対硬度が1.5N/mm2以上を満たしており、硬度と崩壊性のバランスの指標であるHDBIが大きかった。特に、クロスポビドンの量が少ない程、HDBIは大きかった。
表7-1に示す処方にて、内核の厚みの割合が異なる製剤を製造した。まず、外層成分を混合した。表7-1の外層(上)重量に示す外層成分の混合末をとり、表7-1示す内核の直径の臼に入れ軽く振動させて粉末の表面を平滑化し、その上に、結晶セルロース粒(セルフィアCP-203)を所定量加えて、ハンドプレス機(理研製、油圧式プレス機)を用いて、3kNの低い圧力で仮圧縮した。この仮圧縮物を外層が下方になるように直径8mm杵に同心円状に配置し、直径8mmの臼を被せて、仮圧縮物の上に、表7-1の外層(側面+上)重量に示す外層成分を入れて最終成型し、有核型の口腔内崩壊錠を製造した。最終成型物は15kNで打錠した。
表7-4に示す処方にて、内核の厚みの割合が異なる製剤を製造した。まず、外層成分を混合した。表7-4の外層(上)重量に示す外層成分の混合末をとり、直径8mmの臼に入れ軽く振動させて粉末の表面を平滑化し、その上に、結晶セルロース粒(セルフィアCP-203)を所定量加えて、ハンドプレス機(理研製、油圧式プレス機)を用いて、低い圧力で仮圧縮した。この圧縮物を外層が下方になるように直径10mm杵に同心円状に配置し、直径10mmの臼を被せて、仮圧縮物の上に、表7-4の外層(側面+上)重量に示す外層成分を入れて最終成型し、有核型の口腔内崩壊錠を製造した。最終成型物は実施例6-4は8kN、実施例6-5は15kNで打錠した。
成形性がない粒子が錠剤中に均一に分布した普通錠を作製した。まず、表7-7に示す配合割合になるように原料を均一に混合した。この混合末を用いて、直径10mm、打錠圧8kNで打錠し、普通錠を得た。
尚、この普通錠は、実施例6-4で得た有核錠とは成形性のない粒子の分布が異なる以外は、1錠中の含有成分量、錠剤重量、錠剤径、打錠圧を同一条件にして作製した。
このように、成形性のない粒子を多く含む口腔内崩壊錠において、粒子が均一に分布した普通錠に比べて、粒子を内部に包含する有核錠の方が好ましい錠剤物性が得られることがわかった。
打錠圧が6kN~15kNの範囲において、適切な硬度と崩壊性を有しており、打錠圧の許容幅は広かった。
(8-1)アセトアミノフェン含有粒子を含む有核錠
1)アセトアミノフェン含有粒子の製造(旭化成ケミカルズ社製)

得られた錠剤について、口腔内崩壊時間、錠剤硬度及び厚みを測定し、絶対硬度、及びHDBIを算出したところ、表9-3の錠剤物性を有していた。口腔内崩壊時間は30秒以内、絶対硬度が1.5N/mm2以上を満たしており、硬度と崩壊性のバランスの指標であるHDBIが大きかった。このように活性成分を含む場合にも、良好な有核型の口腔内崩壊錠が得られることがわかった。

得られた錠剤について、口腔内崩壊時間、錠剤硬度及び厚みを測定し、絶対硬度、及びHDBIを算出したところ、表9-8の錠剤物性を有していた。口腔内崩壊時間は30秒以内、絶対硬度が1.5N/mm2以上を満たしており、硬度と崩壊性のバランスの指標であるHDBIが大きかった。モサプリド由来の味は抑制され、服用感は良好であった。
1)腸溶性粒子含有粒子

口腔内崩壊時間、錠剤硬度及び厚みを測定し、絶対硬度、及びHDBIを算出したところ、表9-14の錠剤物性を有していた。口腔内崩壊時間は30秒以内、絶対硬度が1.5N/mm2以上を満たしており、硬度と崩壊性のバランスの指標であるHDBIが大きかった。
