Abstract
Description
本発明は、特定の薬物のいずれにも限定されるものではなく、FDDFに製剤化された場合のある薬物の問題を解決するものである。以下の実施例は、本発明の実践を好ましい実施形態の一部によって例示するものである。特許請求の範囲内の他の実施形態は、当業者には明らかであろう。
2つの製剤がマトリックス形成剤を含有することを除いて、Seagar, H.、「Drug-Delivery Products and Zydis Fast Dissolving Dosage Form」、J. Pharm. Pharmaco、第50巻、375〜382頁(1998)に記載されている当技術分野で公知の種類の凍結乾燥FDDFを調製した。以下のTable 1 (表1)に示す組成を有する、製剤1a(非ゲル化)及び製剤1b(ゲル化)を調製した。まず、製剤1aは、化工デンプン、マンニトール及び水を組み合わせ、混合物を15分間75℃まで加熱することによって調製した。続いて、溶液を冷却水浴槽中で5℃まで冷却し、5℃で保持したまま、投入1回当たり150mgで分配する半自動Hamilton投入ポンプを使用して、製剤1aを400個のブリスターポケットに投入した。製剤1bは、ゼラチン、マンニトール及び水を組み合わせ、混合物を60℃で15分間加熱することによって調製した。続いて溶液を、例えば20℃〜25℃の周囲温度まで冷却水浴槽中で冷却し、周囲温度で保持したまま、それを400個のブリスターポケット内の製剤1aを覆う層を成すように投入し、このようにして、2層を形成した。投入した製剤は、次に、前もって-80℃に設定した、液体窒素凍結トンネルを3.25分間通過させることによって、直ちに凍結させた。凍結させた単体は、棚温度0℃、チャンバー圧0.5mbarのUsiforid SMH90フリーズドライヤー内で6時間フリーズドライさせた。フリーズドライさせた錠剤を目視で検査したが、目立った欠陥は認められなかった。錠剤は、37℃の精製水中に置くと、修正USP崩壊法(modified USP disintegration method)で測定して、2秒以内で即座に崩壊した。
温度を5℃に設定して、製剤1aをブリスターポケットに300mg投入し、実施例1と同一条件下で加工する、すなわち凍結し、フリーズドライした。フリーズドライさせた錠剤は、実施例1と同じ方法で検査した。75%の錠剤で著しい表面凝塊物(>2mm)が認められた。
多相凍結乾燥FDDFは、以下のTable 1 (表1)で示す組成を有する、製剤2a(非ゲル化)及び製剤2b(ゲル化)を使用して調製した。総量150mgの製剤2aを、化工デンプン、マンニトール及び水を組み合わせ、混合物を15分間60℃まで加熱することによって調製した。続いて溶液を冷却水浴槽中で5℃まで冷却し、5℃で保持したまま、投入1回当たり150mgで分配する半自動Hamilton投入ポンプを使用して、製剤2aを400個のブリスターポケットに投入した。製剤2bは、ゼラチン、マンニトール及び水を組み合わせ、混合物を15分間60℃まで加熱することによって調製した。続いて溶液を、例えば20℃〜30℃の周囲温度まで冷却水浴槽中で冷却し、周囲温度で保持したまま、それを400個のブリスターポケット内の製剤2aを覆う層を成すように投入し、このようにして、2層を形成した。ブリスターポケットは、続いて実施例1と同じ方法で処理した。
多相凍結乾燥FDDFは、総量150mgの製剤2a(非ゲル化)で調製した。製剤2aは、380個のブリスターポケットに5℃で投入した。続いて、製剤2cと同じ方法で調製した総量150mgの製剤2d(非ゲル化)を、周囲温度で、製剤2aを覆う層を成すように投入した。製剤2a及び2dの組成は、以下のTable 1 (表1)で示される。凍結乾燥させた錠剤を検査したが、5%の錠剤で表面凝塊物が認められた。フリーズドライさせた錠剤の崩壊時間は、修正USP崩壊法で測定して、1秒未満であった。
本発明の多相凍結乾燥FDDFの産業上の利用可能性について試験した。製剤3a及び3bの組成は、以下のTable 1 (表1)で示される。錠剤は総量50kgの製剤3aを使用して調製した。製剤3aは、ゼラチン、マンニトール及び水を組み合わせ、60リットルBecomix(商標)ミキサーを使用して、混合物を60℃まで60分間加熱した。続いて、溶液は、10℃まで冷却水浴槽中で冷却し、10℃で保持したまま、製剤3aを33,600個のブリスターポケットに投入した。この直後に、総量50kgの製剤3bを、周囲温度で、製剤3aを覆うように投入した。製剤3bは、23℃の周囲温度まで冷却する以外は、製剤3aと同じ方法で調製した。続いて、ブリスターポケットを、実施例1と同様の方法で処理した。フリーズドライさせた錠剤の表面欠陥を検査した。単体の上面のひび割れ、凝塊物、及び突き出た凍上などのいかなる欠陥も、99.98%の錠剤で認められなかった。
