| Research Abstract |
In renal transplant recipients, blood clearance of cyclospoline A (CsA) was decreased by oxidative stress. In oxidative stress model rats, elevation of the blood to plasma ratio in the systemic circulation and increase of tissue distribution of CsA were observed. In human, there is also the possibility of decreasing the amount of CsA in plasma contributed to the drug metabolism and tissue distribution. Therefore, reconsideration of the whole blood concentration monitoring of CsA for dose adjustment is needed. In this study, it was difficult to identify the contribution of oxidative stress to the change in drug disposition in obese model rats. However, it was suggested that the change of drug distribution in the blood by oxidative stress affected the first pass effect in oral absorption.
