Description
HME製剤開発では、ポリマーの選択は、HMEの製剤開発時に所望の薬物(薬剤)放出特性(プロフィール)を得る上で、決定的なファクター(要素)となっている。ポリマーの選択が良好になされることで、押出機(押出装置)での処理が容易化される。多くの市販(商用)製剤等級のポリマーは、HME製剤に用いることができ、これは、誘導セルロース、ポリ(メタクリレート)誘導体、ポリ(エチレン−コ−ビニルアセテート)、ポリ(エチレン)、ポリ(ビニルアセテート−コ−メタクリル酸)、エポキシ樹脂及びカプロラクトン、ポリ(エチレンオキシド)、ポリ(エチレングリコール)、及び、種々のワックス、脂肪や、脂質ベースの賦形剤(ゲルシア(Gelucire)[登録商標]、ウィテップゾール(Witepsol)[登録商標]、ラブラフィル(Labrafil)[登録商標]や、他のもの)を含む他のものを含む。
本発明の改良(修正、変更)された放出製剤は、膜制御製剤としても提供されることができる。本開示の膜制御製剤は、迅速放出芯部を調製することによって作ることができる。この芯部は、ゼラチン殻部によって封入された液体、半固体又は固体であることができ、該殻部を機能被膜によって被覆する。膜制御被膜の存在下又は非存在下で、芯部自体がミニカプセルからの医薬用化合物の放出速度を制御するように、芯部は、液体、半固体、又は固体であろうとも、製剤化(調剤化、formulated)されることができる。膜制御投薬形態の詳細を以下に示す。本発明の或る実施形態では、医薬用化合物は、複数のミニカプセル膜制御製剤に与えられる。活性医薬成分は、液体、半固体、又は固体の物質として製剤化することができ、これにより、溶解性、浸透性、又は溶解速度が高められ、又、この活性医薬成分は、2層又は3層のミニカプセルの芯部として利用される。このミニカプセルは、混和性の芯部の成分と殻部の成分とを分離するために、付加的な緩衝層の有無にかかわらず、付加的に殻部を備える。このミニカプセルの直径は、0.5mmから約5.0mmまでの範囲であってよい。同一の活性(成分)又は1以上の他の活性成分の付加的な医薬用化合物は、流動床コーター又はパン・コーティング・システムを用いて、溶液又は懸濁液から噴霧することができる。
結腸への薬剤の経口送達は、結腸疾患(潰瘍性大腸炎、クローン病、癌、及び感染)の治療において価値がある。これによって、高い局所濃度(濃縮)が達成できる一方で、上部GITでの薬物の放出のために、或いは不要な組織吸収のために、生ずる副作用を最小限にすることができる。結腸はリンパ系組織に富んでおり、結腸粘膜のマスト細胞に抗原が取り込まれることで、抗体の迅速な局所産出(local production)が生じ、これは、効率的なワクチン送達を援助する(サラシジャ、エス・アンド・ホタ・エー、コロン・スペシフィック・ドラッグ・ディリバリ・システムズ、アイエヌディ・ジェイ・ファーム・エスシーアイ、62: 1-8, 2000(Sarasija, S. and Hota, A.. Colon-specific drug delivery systems. Ind J Pharm Sci, 62: 1-8, 2000))。結腸は、吸収されにくい薬物分子が、改善された生物学的利用能を持つと考えられる部位として、注目されている。結腸のこの部位は、胃及び小腸と比べて、多様性及び活動の強度が小さく、やや厳しくない環境を有するものとして認識されている。更に、結腸は、より長い保持時間(retention time)を持っており、吸収されにくい薬物の吸収を増強する薬剤に対して、高い反応性を示す。投薬形態を遅延又は標的化することとは別に、信頼できる結腸薬物送達は、又、経口的に投与され、消化されず、変化せず、そして十分に活性のあるペプチド薬物の結腸での吸収にとって、重要なスターティング・ポジションであり得る。大腸は、相対的に、ペプチダーゼがないことから、そのような特別の送達系(送達システム)は、経口投与後に十分に吸収された薬物を得るためのまずまずの機会(fair chance)を得る。結腸に対する薬剤の標的化のための最も単純な方法は、層が厚い従来の腸溶性被膜(enteric coatings)を適用することで、或いは非常にゆっくりと放出するマトリックスを適用することで、より穏やかな放出速度、或いはより長時間にわたる放出を得ることである。
