ABSTRACT
Epilepsy is a common nervous system seizure disease in children,20%-30% of them is intractable epilepsy.The pathogenesis of intractable epilepsy in children is not yet identify.Some research think that this may be associated with resistance of a variety of diffe-rent mechanisms of antiepileptic drug and abnormalities of multidrug resistance gene expression.The most investigation of multidrug transpor-ter is P-glycoprotein,multidrug resistance-associated protein.They are present in cell membrane and belong to adenosine triphosphate-dependent membrane transport protein.Studies have showed that over-expression of multidrug transporter in temporal lobe brain tissue of patients with refractory epilepsy and animal model of chronic epilepsy reduce the concentration of therapeutic drug in cells.They result in resis-tance by releasing the energy and transferring large amounts of anti-epileptic drugs to exterior of brain capillary endothelial cells in way of active transport.The relationship between multidrug transporter′s structure,distribution,functions and drug-resistant epilepsy are reviewed.
