実施例1
組成物の選択によるデポー中の各種液晶相の利用可能性
ホスファチジルコリン(「PC」、エピクロン200)とジオレイン酸グリセロール(GDO)とを異なる割合で含み、EtOHを溶媒として含む注射製剤を調製し、デポー前駆体製剤を過剰量の水で平衡化した後、各種液晶相が得られることを例証した。
溶媒(EtOH、PG、及びNMP)の添加によるPC/GDO(5:5)又はPC/GDO(4:6)の粘度
約25%EtOHを有するPC/GDO/EtOHの混合物を、実施例1の方法に従って製造した。回転蒸発器(真空、40℃で1時間、続いて50℃で2時間)を用いて混合物からEtOHを完全又はほぼ完全に除去し、得られた混合物をガラスバイアルで計量した後、1、3、5、10、又は20%の溶媒(EtOH、プロピレングリコール(PG)、又はn−メチルピロリドン(NMP))を加えた。試料を数日間平衡化させた後、自動間隔設定(automatic gap setting)を備えるキャリメド(CarriMed)CSL100レオメータを用いて粘度を測定した。
ペプチドであるオクトレオチドを含むデポー組成物の調製
酢酸オクトレオチド(24mg、60mg)を、0.1gのEtOHに溶解した。次に、0.36gのPC及び0.54gのGDOをこの溶液に溶解し、デポー製剤前駆体を得た。過剰量の水相に製剤前駆体を注入(注射器23G、0.6mm×30mm)したところ、モノリシック液晶相(I2構造)が得られた。すなわち、水性環境に曝露された後もオクトレオチド(2.4%又は6.0%)のモノリス形成及び相挙動に変化はなかった。
塩化オクトレオチドの調製
イオン交換カラムに酢酸オクトレオチド(OCT(Ac))の水溶液を流して、OCT(Ac)から塩化オクトレオチド(OCT(Cl))を調製し、陰イオン交換樹脂ダウエックス1×2(フルカ)でプレパックし、注射用水(WFI)で前平衡させた。採取した画分の導電率を測定して、WFI中の適正なOCT(Cl)の画分を確認した。当該画分を貯留し、試料を一晩フリーズドライして凍結乾燥させて、OCT(Cl)を白色の粉末として得た。
酢酸オクトレオチド及び塩化オクトレオチド組成物
OCT(Ac)及びOCT(Cl)の液晶製剤を次の方法で調製した。大豆ホスファチジルコリン(SPC:リポイドS100、ドイツのリポイド社より)、ジオレイン酸グリセロール(GDO:デンマークのダニスコ社より)、エタノール(EtOH、99.5%)、及びOCT(Ac)(米国カリフォルニア州のポリペプチドラブス社)若しくはOCT(Cl)(実施例4と同様に調製)を、均一な液体混合物が得られるまで、過剰量のEtOH中で混合した。その後、過剰の溶媒を回転蒸発器で蒸発させてEtOH含有量を5重量%まで調整した。試料の組成を下記表に示す。
製剤組成(重量%)
LCデポー製剤中のオクトレオチドの安定性:酢酸オクトレオチド(OCT(Ac))と塩化オクトレオチド(OCT(Cl))の比較
実験の詳細
OCT(Ac)及びOCT(Cl)のLC製剤を、実施例5で上に記載のように調製した(OCT(Cl)は、イオン交換カラムクロマトグラフィーによりOCT(Ac)から調製された。実施例4を参照のこと)。製剤の組成を下記表に示す。製剤を、40℃/75%相対湿度の人工気候室(ターマック)で、テフロン(登録商標)コーティングされたゴム栓を備えたガラスバイアル中で保存した。オクトレオチド含有量(名目上の含有量の%として表す)、ID、及び関連物質を、215nmでUV検出するHPLCにより測定した。
保存期間及び条件の関数としてのオクトレオチド含有量(名目上の濃度の%として示す)を図3に示す(表2を参照のこと)。対イオンを酢酸塩から塩化物塩に変更する効果は予想外に高い。40℃にて4週間後のOCT(Cl)製剤(#192)にはほとんど変化が起こっていないが、OCT(Ac)製剤(#174)中のオクトレオチドには著しい分解が起きる。これは、分解産物の量(215nmのUV検出でのピーク面積全体の%として表す)が保存期間及び条件の関数として示されている図4でさらにはっきりと分かる。結論として、塩化物塩である対イオンの安定性増強効果は驚くほどに高く、これはオクトレオチドのデポー製剤製品の貯蔵安定性の観点から非常に有益である。
共溶媒添加によるPC/GDO混合物の粘度の別の例
PC/GDO及び共溶媒の混合物を、下記表に示す割合で、実施例1及び2に記載の方法に従って調製した。試料を数日間平衡化させた後、フィジカUDS200レオメータを使用して25℃で粘度測定を行った。
