Description
ングするための耐酸性バンディング溶液(banding solutions)、ならびに、例えばヒト
または動物に少なくとも1つの医薬、獣医製品、食品および栄養補助食品を経口投与するためのこのようなカプセルの使用に関する。
で利用されており、薬剤、ビタミン剤のような薬学的活性物質ならびに固形および液体の両方の他の食物を保持し、かつ胃の中の酸性条件からそれらを保護している。
PMC方式で作られる。その結果、カプセルシェル自体が耐酸性であり、耐酸性を達成するための充填後処理を必要としない。
要がある。
内容物の漏出を防止するために一般に用いられる。
のキャップと本体とを互いに直接密封することである。例えば、特許文献3;特許文献4;特許文献5、特許文献6;特許文献7;特許文献8;特許文献9;および特許文献10を参照のこと。ツーピースハードカプセルをバンディングする方法、およびバンディング用の装置は、例えば、特許文献11;特許文献12;特許文献13;特許文献14;特許文献15;特許文献16;特許文献17および特許文献18に開示されており、これらは、すべて参照により本明細書に組み込まれている。
プセルの開発には、バンディングされたカプセルの耐酸性を保証するためにバンディング溶液の組成物をポリマーの性質に適合させる必要性が生じる。例えば、特許文献19;特許文献20を参照のこと。
の安全かつ有効な方法を開発する必要がある。
本明細書に用いるように、以下の用語、成句および記号は、それらを用いる文脈が、特に明記する場合を除き、一般に、以下に記載する意味を有するものとする。
酸セルロース(cellulose acetyl phthalate);ならびに非商標名、例えば:セラセフェート(cellacephate)(イギリス薬局方)、酢酸フタル酸セルロース(cellulose acetate phthalate)(日本薬局方)、酢酸フタル酸セルロース(cellulosi acetas phthalas)(欧州薬局方)、およびセラセフェート(cellacefate)(米国薬局方)。
れるわけではない。
カプセル製造後の適当な処理によって得られたツーピースハードカプセルのことであり、WO2011/030952、EP22236851および/またはU.S.2010/113620A1に記述されたカプセルを含むが、これらに限定されるわけではない。
したがって、本開示の一態様は、耐酸性ツーピースハードカプセルをバンディングするための耐酸性バンディング溶液であって、上記カプセルが、伸縮自在に係合したカプセル部分を含み、かつ密閉されているがバンディングされてないこのようなカプセルと比較して改善された耐酸性の性質が与えられている耐酸性バンディング溶液を提供する。
合物である。
と。
酸性フシン(Acid Fushine));アルラレッドE129、FD&Cレッド40;インジゴカルミンE132、FD&Cブルー2;ブリリアントブルーFCF E133、FD&C
ブルー1;カラメル、USP E150c;FD&Cグリーン3;FD&Cレッド3/エ
リトロシン;アゾルビン;ブリリアントブラック;銅クロロフィリン錯体または銅クロロフィリンナトリウム;ポンソー4R;パテントブルーV;キノロンイエロー;クルクミン、赤キャベツ;およびそれらの混合物を含む可溶性の染料が挙げられるが、それらに限定されるわけではない。薬学的に許容されるまたは食品に許容される着色剤の他の例としては、二酸化チタン、黄色酸化鉄、赤色酸化鉄、黒色酸化鉄、カンドリン銀微粉(Candurin
silver fine)、およびそれらの混合物を含む顔料が挙げられるが、それらに限定されるわけではない。
Mカプセル(HPMC)である。本開示によるバンディング溶液および方法は、あらゆるサイズのDRcapsTMカプセルに適用することができる。
バンディング溶液の3つの試料を、耐酸性ポリマーとして、それぞれHPMCP(HP−55)、CAPまたはHPMCASを用いて調製した。使用したアルカリ化合物は、NH3濃度35%のアンモニア水溶液(Fisher Scientificからのアンモニア溶液0.88S.G.(35%NH3))であった。最初に、ポリマー粉末の質量による適当な量を、室
温、撹拌下で水中に分散させて所望の質量比を得た(表1を参照のこと)。次いで、ポリマー粒子がすべて溶解するまで指示量のアンモニア溶液を穏やかな撹拌下で徐々に分散液に加えた。パテントブルーV−C.I.フードブルー5E131の0.1%溶液(ポリマー質量に基づく)を加えてバンディングの目視を補助した。表1は、得られたバンディング溶液の組成物および特徴を示す。
ミノフェノール(APAP)の混合物をカプセルに充填した。
てのこれらの結果からより小さなカプセルを推定してもよい。
