Description
閾値レベルモデリング
ランソプラゾールのヒトにおける以下の単回用量静脈内投与から得られた血漿中濃度データについて、PPIが有効である上記閾値濃度を確定するために、モデリングした。まず初めに、投与後(絶食状態下で)5時間にわたって測定した胃のpHを、血漿中濃度の関数としてプロットした。しかし、胃のpHと薬物の血漿中濃度との直接的な関連性は立証することができなかった。実際に、これらのパラメータを用いてデータをプロットすることにより、反時計回りのループが得られた。次いで、薬物濃度と薬効との有用な関連性を図で表すために、薬効コンパートメントモデルを使用した。それゆえに、PKコンパートメントが、個々の薬効コンパートメントに関連づけられているようなモデルが提案された。このモデルによって、PKコンパートメントに関連づけられている小型薬効コンパートメントを使用して、胃内pHと濃度との間の傾向を図で表すことに成功したことが証明された。同一の静脈内のデータを用いて、薬理効果をシグモイドEmaxモデルを使用してモデリングし、PKは2種類のコンパートメントモデルを使用してモデリングした。このモデリングにより、ランソプラゾールの薬物動態特性を最初に立証し、次いで、薬物血漿中濃度と胃内pHとの関連性を立証し、薬力学的パラメータの推定値を得た。このモデリングにより、図1に示すグラフが提供された。このグラフにおいて、薬効コンパートメント濃度(この濃度は、定常状態での血漿中濃度と同一であると仮定されている。)はx軸上に、および胃のpHはy軸上にある。モデリングの図解によって示されているように、薬効(基準線よりも高くなっている)は、およそ100ng/mlを超える濃度で始まり、およそ450ng/mlを超える濃度で横ばい状態になる。したがって、基準線から所望の薬理効果の最小推移を得る目的のためには、およそ100ng/mlの閾値濃度を得る必要があると判断された。
吸収部位の検討
これは、健常成人男性8例における、第1相、非盲検、非無作為化、4期間、単回投与の、クロスオーバー試験であった。ランソプラゾール遅延放出カプセル剤(30mg)由来のランソプラゾール顆粒を粉砕して、重炭酸ナトリウム、デンプンおよび放射性標識と混合したものを含む、即席で準備された製剤を、遠隔制御カプセルによって被験者に投与した。この遠隔制御カプセルは、粉末薬、放出機序、および外部信号を受信する磁気レシーバーを保有することができる、消化されない殻からなる。1期、2期および3期の間に遠隔信号を受けて、カプセルは、この内容物を胃腸管内の事前に指定された部位に放出した(下記表1を参照のこと)。デンプンおよび放射性標識を有する、ランソプラゾール遅延放出30mgカプセル剤を、4期中に経口投与し、および生物学的利用能の参照として使用した。
Claims (5)
