Description
本発明における活性成分は、治療効果を有し、そして前記ヒトまたは他の哺乳動物の胃に送達する必要のある成分であれば何れでも良い。活性成分が胃に送達される前に放出されると、胸やけ、食道やけ、飲み込み時の痛み及び/または困難さ、及び/または胸骨の後ろ及び/または中央の痛み等の愁訴を患者が起こす時、本発明の有効性が特に実感される。このような活性成分は、溶解時のpHが2〜3未満である薬剤、細胞毒活性を有する薬剤(腐食剤)、及び/または粘膜乾燥を引き起こす高浸透圧性溶液を局所的に発生させる薬剤である。好ましい活性剤は臭化エンペロニウム、ドキシサイタリン、及びその他のテトラサイクリン/抗生物質、鉄剤、塩化カリウム、キニジン、非ステロイド性抗炎症薬、アルプレノロール、アスコルビン酸、カプトプリル、テオフィリン、ジドブジン(AZT)、及びビスホスホネートから成る群より選ばれる。より好ましい活性剤はリゼドロネート、アレンドロネート及びパミドロネートであり、最も好ましくはリゼドロネートである。
種々の疾患または傷害に罹患したヒトまたは他の哺乳動物は、活性成分を含有する新規な剤形をそのヒトまたは他の哺乳動物の胃に送達することによりうまく治療することができる。本明細書に記載する新規な経口用のほぼ楕円形のフィルムコーティング剤形は、食道を素早く通過し、それゆえ剤形を胃に効率的に送達し、口、咽頭及び/または食道中へのリゼドロネートの所望しない放出を回避しまたは最小化して、これによりこれらの組織の上皮または粘膜層のびらん、潰瘍形成または他の同様の炎症を防御する。本明細書において用いられる用語「胃腸管」は消化管、即ち口から肛門まで続く長さが約30フィート(約9m)の筋結織膜管に関する。本明細書において用いられる用語「上部胃腸管」は口腔前庭、咽頭、食道及び胃を意味する。本明細書において用いられる用語「下部胃腸管」は小腸及び大腸を意味する。
これは長さが約4インチ(約10cm)の粘膜管であり、後ろに食道へと続き、粘膜層、繊維層及び筋層から構成されている。
本明細書において用いられる用語「フィルムコーティング」とは、活性成分に施される、活性成分と組み合わされる、活性成分と混合される、または活性成分に添加される薬学的に許容しうる賦形剤の混合物に関する。圧縮錠剤、ビーズ剤、粒剤または圧縮して錠剤化される活性成分の粒子に前記コーティングを施すことができる。選択されるコーティングは、選択された特定の活性成分に適合するものでなければならない。
上述のように、本発明はヒトまたは他の哺乳動物の胃に活性成分を送達するのに効果がある新規なほぼ楕円形のフィルムコーティング経口用剤形に関する。新規なほぼ楕円形のフィルムコーティング剤形は、上部胃腸管を素早く通過し、個体の胃に到達するまで活性成分の送達を回避する。胃に到達すると、剤形は溶解し、小腸及び/または大腸を通して活性成分を吸収することができるようになる。それゆえ、上部胃腸管の組織、特に口腔前庭、咽頭及び食道の上皮及び粘膜層が活性成分と直接接触しないことになり、活性成分は適切な部位で吸収される。
(a)適切な活性成分(b)コーティングのタイプとそれに付随する前記コーティングの所望する厚さ及び透過性(膨潤性)
(c)コーティング自体及び/またはコーティングされた錠剤、粒予、ビーズまたは顆粒内の時間依存性条件、及び(d)顆粒化された活性成分の粒子径 上述のように、薬学的に許容しうる賦形剤は、ポリマー、樹脂、可塑剤、充填剤、潤滑剤、結合剤、崩壊剤、溶剤、共溶剤、界面活性剤、保存剤、甘味剤、香味剤、緩衝系、医薬グレード色素及び顔料を含むが、これらに限定されるものではない。好ましい溶剤は水である。
