Outline of Final Research Achievements |
The aim of this study was to determine whether P-glycoprotein (P-gp)-mediated drug-endogenous substrates interactions (DEIs) with androgens can occur in vivo. Cell-based studies have identified several drugs, including centrally acting drugs, that can interact with androgens. Moreover, animal studies with these drugs revealed that the brain permeation of androgens is affected by DEI. This study indicates that P-gp-mediated DEI can occur at blood-brain barrier in vivo.

Academic Significance and Societal Importance of the Research Achievements |
相互作用は医薬品どうしによるものが一般的に知られており、その飲み合わせの注意喚起が行われている。本研究の成果から、医薬品どうしの相互作用だけではなく、生体内基質と医薬品のP-gpを介した相互作用は生体内基質の体内動態に影響を及ぼす可能性が示唆された。そのため、生体内基質との相互作用を考慮した医薬品の新しい注意喚起 (添付文書への記載の追加や修正など) が行われると期待される。
