Description
。肥満に於けるそれと同様な挙動が新生児(neonate)で観察され、そこでは周辺コンパートメントの容積が成人に於けるより比較的大きく、それは新生児に於ける身体脂肪の比較的高い比率により説明される。新生児は又プロポフォール注入の終了後一般的麻酔からもっと速く目覚めるが、後遺症からは比較的ゆっくりにしか回復せず、それは低下したシステム的クリアランスに帰せられる(非特許文献7)。
function)として使われる。生理学的パラメーターの実時間測定と組み合わせて、生理学的知識を使わない従来技術で引用されるブラックボックス(black−box)デバイスより実質的に良い閉じた制御サイクルが創られる。
)用のタンパク質の表現と機能を特徴付けるバラメーター、を含む。これらのパラメーターは直接測定されるか、又はそれらは、或る母集団について、年齢、性別、体重及びやせたボデイマス(body mass)の様な容易に測定される患者パラメーターと相関付けられる(非特許文献9)。これらのパラメーターの或るもの又は幾つかは本発明の手順で使われる。又血流レートの様にこれらのパラメーターの或るもの又は幾つかは時間が経って変化するので、シミュレーション時のこれらの変化を考慮することが賢明である。
ー(transporter)に関する表現データ(expression data)が、患者に個別に誂えられた用量を決定するよう使われ得るかを説明している。
応用例は、バイエルテクノロジーサービスゲーエムベーハー(Bayer Technology Service GmbH)により開発された、商業的に入手可能な生理学ベースの薬物動態学的モデルピーケー−シムアールと、インターネット上で刊行され、入手可能なチバ−トレイナーディプリフューザーテーエム(TIVA−Trainer DiprifusorTM)ソフトウエアと、を用いたシミュレーションに基づく。ピーケ
ー−シムアール用の物質依存の入力パラメーターとしてプロポフォールの下記値が使われた(表1)。
BMI)又は身長(H)から選択された2つのパラメーター(これらのパラメーターは式BMI=BW/H2により関係付けられる)と、を引用することにより特徴付けられる、仮想的個人(virtual individual)のシミュレーションを可能にする。もう1つの重要な入力パラメーターはクリアランスであり、それは物質の除去レート(rate of elimination)である。プロポフォールは肝臓で代謝される。代謝酵素の活動は年齢に依存(age−dependent)することが知られている。図2は年齢の関数としてのプロポフォールクリアランスを説明する実験データ(シンボル)を通るあてはめ(fit)(線)を示す。該“個別創生”機能は表2で引用された研究をシミュレートするため使われる。これらの場合は又チバ−トレイナーディプリフューザーテーエムソフトウエアを、そして小児科の研究の場合はパエドフューザーモデル(Paedfusor model)を、使ってシミュレートされた。
。この場合、ピーケー−シムアールで計算された脳内の活性成分濃度の相対標準偏差は18%であり、チバ−トレイナーでの効果コンパートメント濃度のそれは21%であった。
