| Outline of Final Research Achievements |
The aim of the present study was to investigate the mechanism of antiepileptic drug transport across the placenta to reduce their risk to the fetus. The accumulated amounts of antiepileptic drugs in the placental cells were in the order, gabapentin > lamotrigine > levetiracetam > topiramate. We concluded that the influx of gabapentin, lamotrigine, and valproate into the placental cells was transporter-mediated. Furthermore, an experiment using transporter inhibitors and siRNAs indicated that L-type amino acid transporter 1 (LAT1) largely contributed to the transport of gabapentin into the placental cells.
