Description
本発明は、経口投与用の医薬製剤に関し、本医薬製剤は有効量の水溶性又は非水溶性有効成分の粒子を薬学的に許容可能な水性ビヒクル中に含む。
初期スクリーニングを行って、グリセリンと水の溶液中での親水コロイド重合体の物理的特性を調べた。1.5%のアルギン酸ナトリウム(Nelanders International社、ミシサーガ、オンタリオ州)と、2.0%の2.0%アルギン酸プロピレングリコール(Colloid602(Nelanders International社、ミシサーガ、オンタリオ州)と、2.0%のKappa Gelcarin GP911、2.0%のKappa(Gelcarin GP812)、1.0%のキサンタンゴム(Tixacan200)(FMC Corporation社、フィラデルフィア、ペンシルバニア州)を50:50でブレンドされたグリセリン/水に分散させた。試験の結果、どの親水コロイド重合体も耐流出特性を有していなかった。結果を表1に示す。
アルギン酸ナトリウム、カラギーナン、イナゴマメゴム、グアーガム、ヒドロキシプロピルメチルセルロース及びカルボキシメチルセルロースナトリウムの溶液にキサンタンゴムを添加する実験を行った。これらの溶液は、上の実施例1で説明したものと同じやり方で調製された。結果は、キサンタンゴムとイナゴマメゴムが、試験したゲル化剤の全てではないが一部との相乗効果を有していることを実証した(表IIを参照のこと)。プラスに働く相乗作用により、より少ないゲル化剤で、望ましい粘度が得られた。但し、キサンタンゴム及びイナゴマメゴムは、望ましくない繊維性の弾性テクスチャにも関係しているようであった。
水/グリセリン混合物に単独で添加されたカラギーナンは、堅い、非流動性の組成物となった(表1)。しかしながら、1.5%のアルギン酸プロピレングリコールと0.5%のカラギーナンの組み合わせは、所望の耐流出特性に近いレオロジーをもたらした。カラギーナンをイナゴマメゴム及びキサンタンと一緒に用いることで、イナゴマメゴムとキサンタンゴムだけの場合よりも繊維性の低いゲルが得られた。また、カラギーナン/イナゴマメゴム/キサンタンゴム混合物は、スプーンに分注した際、滑らかに広がる。カラギーナン/イナゴマメゴム/キサンタンゴム混合物にグアーガムを添加しても、製剤にこれ以上の耐流出特性が付与されたようには見えなかった。
プソイドエフェドリン0.27%/親水コロイド重合体混合物(0.375%カラギーナン/0.625%キサンタンゴム/0.125%イナゴマメゴム)組成物を以下のやり方で調製した。カラギーナン(1.875グラム)、イナゴマメゴム(0.625グラム)及びキサンタンゴム(3.125グラム)を500グラムのグリセリン水溶液に添加し、約60℃〜70℃まで1時間に亘って混ぜながら加熱した。混合物を約40℃〜50℃まで冷却した。ブチルパラベン(0.25グラム)をプロピレングリコールに溶解させ、この冷却した混合物に添加した。
様々な量のイナゴマメゴムと混合したトラガカントを耐流出特性について試験した。グリセリンは共溶媒として評価された。
8グラムのイナゴマメゴム(AEP Colloids社)及び32グラムのトラガカントゴムUSP(Red Carnationブランド、LV Lomas社)を1000mLのグリセリン中に、約500rpmでプロペラ式混合装置を用いて分散させた。740グラムの水をこの混合物に添加して、次に、緩やかにかき混ぜながら混合物を65℃まで10分間に亘って加熱した。緩やかに攪拌したままで、この混合物を室温まで冷却した。6.0gのブチルパラベン(NIPA Laboratories社)を200gのプロピレングリコール中に溶解し、次に、1.94グラムの酢酸プレドニゾロン(Grand Pacific社)を添加し、約300rpmでプロペラ式攪拌装置を用いて分散させた。次に、約300rpmで混ぜながらバッチに添加した。4.0gのスクラロース(McNeil Specialty Products社)とチェリー風味の着香料を最終混合段階で添加した。
