Description
(a)リン脂質(例えばレシチン又はその誘導体の1つ)、ステロール(好ましくは、植物誘導ステロール、最も好ましくは還元された植物誘導ステロール)、および選択された薬剤を非極性溶媒(好ましくは、酢酸エチル又はヘプタン)中にて沸点で混合する工程;
(b)溶媒を高温で除去させた後、固形残渣を収集し、全ての成分の溶解度を維持させる工程;
(c)固形残渣を小片に破砕させ、激しい攪拌下で水中に分散させ、これら成分のいずれか1つの分解温度あるいは水の沸点のいずれか低いほうの温度でミルク状溶液を形成させる工程;
(d)該ミルク状溶液を最大圧力で操作させたホモジナイザー(例えば、Gaulin Dairyホモジナイザー又はその他の適当な均等物)に通過させる工程;
(e)適当な乾燥助剤(例えば、Maltrin, Capsule M又は適当な均等物)を添加し、ついで該ミルク状溶液を噴霧乾燥又は凍結乾燥させて固体を形成させる工程であって、この固体は適当な賦形剤を添加することにより錠剤又はカプセルに組み込まれる。
シクロスポリンA(0.50gm)、ウルトラレック(Ultralec P, Archer Daniels Midland, Decatur, IL、米国)(1.00gm)および大豆スタノール(0.50gm)を、30mLのコレックス(Corex)ガラス管中にて混合した。酢酸エチル(5.0mL)をこのガラス管中に添加し、その混合物を60℃の水バスで加温し、全ての固体を溶解させた。この透明な溶液を渦攪拌機を用いて完全に混合させた後、時折60℃まで加温して酢酸エチル溶媒の除去を容易にしつつ、この溶媒を窒素気流中にて除去した。残留溶媒を真空下で固形物から除去した。このサンプルを完全に乾燥させた後、水(10mL)を添加し、その混合物を4分間超音波処理し、クリーム状溶液を生成させた。マルトリン(Maltrin)(500gm)を水3mLに溶解させ、これを攪拌下で上記クリーム状溶液に添加した。粒径分析のため少量を採取した後、残った溶液をドライアイスアセトンバス中にて凍結させ、凍結乾燥させた。この凍結乾燥物質の少量を水に再溶解させ、この再水和物質の流径分布を決定し、この再水和物質が得られた超音波処理混合物のものと比較した。以下の表に示すように、この再水和サンプルの流径分布は、乾燥および再水和が、出発物質のものと比較したとき、流径分布を有意に変化させるものでないことを示している。
水和調剤シクロスポリン 4.13 14.20 45.04
乾燥、再水和エマルジョン 4.05 9.90 26.58
*粒子の10%は粒径がこの値(μm)より小さい。他のパラメータは粒子の50%および90%についての粒径をそれぞれ指している。
(シクロスポリン)
調剤されたシクロスポリンA(125mg)、澱粉(75mg)、CaCO3(50mg)およびSiO2(3mg)を一緒に混合し、#1ゼラチンカプセル内に充填した。このゼラチンカプセルを攪拌下で37℃の水に添加したとき、カプセルが溶解した後、10分以内で粉体が分散した。
2匹のイヌに対し、25mgのネオラール(Neoral)カプセル(Sandimmune)を投与し、他の2匹のイヌに対し、25mgのカプセル化調剤シクロスポリンA(1.25mg/kg/日)を投与した。投与後0,1,2,4,8,12および24時間目で、血液をEDTAを収容した試験管に採取した。少なくとも72時間の洗浄期間の後、動物に対し代替の投与を与え、血液採取を同一の時間間隔で繰り返した。全てのサンプルを収集した後、これらをCyclo-Trac SP検査(Diasorin, Stillwater, MN)を用いてシクロスポリンについて検査した。シクロスポリンAをこのようにして調剤したとき、血液濃度-時間曲線の下の面積はネオラールの投与について見出されたものの約67%であった。血液濃度-時間曲線のピーク濃度は、ネオラールについて2時間で生じたのに対し、調剤したシクロスポリンでは4時間で生じ、固体のより長い溶解時間を反映するものであった。
