Abstract
【解決手段】 本発明に従って、複数の不規則な形状のコア及びその中に活性薬剤を含有する、胃腸管における活性薬剤の改変された放出のための、薬学的処方物が提供される。
Description
本発明は、経口投与後に限定された若しくは部位特異的な吸収及び/又はpH依存的吸収を伴う薬学的活性薬剤の改良された吸収及びバイオアベイラビリティーを示す徐放性薬学的処方物に関する。
経口投与後の薬理学的に活性な化合物の吸収プロセスは、多くの場合、有効成分の物理化学的性質に依存する。この依存性は、腸管の特定の部位を所定薬物の吸収に対してより反応しやすくする。吸収の特定の部位において薬物の持続時間が長くなるとき、最適な吸収が達成される。吸収部位を通る薬物の通過(transit)が短い場合、最適状態に及ばない血漿レベルが達成され、その結果、短い作用持続時間がもたらされる。さらに、それが、経口投与のための徐放性処方物の製造を困難にしている。
本発明に従って、複数の不規則な形状のコアを含有し、有効成分が吸収限定部位を有する薬剤(例えば、摂取後6時間よりも短い吸収ウィンドウ(windows)を有する薬剤)から選択される、胃腸管における有効成分の徐放のための薬学的処方物が提供される。それらの例としては、心臓血管薬の部類における特定の薬剤、ACE阻害剤、抗菌剤、プロトンポンプ阻害剤、抗ウイルス剤、癌化学療法薬、ビタミンB6誘導体、ベンゾジアゼピン、鎮痛薬、抗コリン作動薬、抗−ADHD剤、抗癲癇剤及びホスホジエステラーゼIII阻害剤であるが、本発明はこれらの列挙に限定されない。

組成を第3表に示す。薬物及び賦形剤を、18−メッシュシーブを通して篩過し、V−ブレンダー中で5分間混合した。次いで、混合物をローラー圧縮した。ローラー圧縮機の加工パラメーター:ローラー速度=8rpm、供給スクリュー速度=25rpm;グラニュレーター速度=80rpm;ローラー圧=100bar;及びトップ/ボトムスクリーンは1.25mm/0.63mmである。得られた顆粒を篩過し、20〜50メッシュシーブの間に保持されたものを回収した。顆粒をサイズ0白色不透明coni−snapカプセル中にカプセル化し、溶解について分析した。図4は、PD0150−182Eに関する平均溶解プロフィールを示す。
