Outline of Final Research Achievements |
This study demonstrated that the preparations of magnesium and aluminum inhibited the transport of rosuvastatin in the direction of absorption in Caco-2 cells by suppressing the function of organic anion transporting polypeptide (OATP). In addition, ferric citrate accelerated the transport of rosuvastatin in the direction of absorption in Caco-2 cells by enhancing the function of OATP. These results are the first report in that OATP is involved in the interaction between the preparations of metal cation and rosuvastatin, and provide important findings into the interaction between statins and the preparations of metal cation, which are often used concomitantly in a clinical setting.

Academic Significance and Societal Importance of the Research Achievements |
本研究は、脂質代謝異常症治療薬の血中濃度が、金属カチオン製剤の併用により、顕著に低下するメカニズムを明らかにしたものである。本研究は、これまで、キレート形成や吸着のような物理化学的相互作用のみを引き起こすと信じられてきた金属カチオン製剤が、薬物トランスポーターの機能抑制および機能亢進を介した生物薬剤学的相互作用も引きおこすことを示した初めての報告である。また、本研究成果の実臨床への適用により、相互作用に基づく医薬品の増量を防ぐことに繋がり、医療費抑制にも繋がると考える。
