Research Abstract

経口投与後の薬物に対する初回通過効果におけるP-gp 及びCYP3Aの寄与について、quinidineをモデル薬物として検討した結果、P-gp、CYP3A活性の強さに関わらず、quinidineの小腸からの吸収クリアランスはほぼ一定であること、一方で、肝抽出率、小腸抽出率は、testosteroneの肝、小腸代謝固有クリアランスとそれぞれ良好に相関することが明らかとなった。難溶解性薬物griseofulvinの経口吸収挙動の大きな個体差は、小腸内移行速度の個体差に依存したin vivo溶解挙動の個体差によるものと考えられた。更に、輸送担体を介して吸収される薬物の吸収挙動の予測を目的とし、オリゴペプチドの輸送系であるPEPT1を対象とし、その代表的な基質であるcephalexinの吸収について検討し、cephalexinの吸収挙動を良好に描写することに成功したほか、cephalexinの吸収に対するPEPT1、受動拡散の寄与を定量的に評価することに成功した。
