| Research Abstract |
It has been elucidated that the hepatic expression of the drug metabolizing enzyme is altered with a decreased renal function. The expression of electrolyte transporter in choroid plexus also varies when renal function is impaired. These findings suggest that an increased sensitivity of central nervous system to therapeutic compounds is caused by the increase in the drug disposition to central nervous system. The increased drug disposition seems to be a result of an altered hepatic enzyme expression in conjunction with a perturbed homeostasis of central nervous system with an altered choroid plexial expression of electrolyte transporters.
