Brief summary
This purpose of this study is to measure the concentrations of two anti-epileptic drugs (Eslicarbazepine acetate and oxcarbazepine) and their metabolites in the cerebrospinal fluid and blood plasma of healthy subjects and also to assess how these drugs are tolerated.
Interventions
Oral administration 600 mg QD morning from Day 1-3 and 1200 mg from Day 4-9
Oxcarbazepine 300 mg BID from Day 1-3 (morning and evening) and oxcarbazepine 600mg BID from Day 4-9 (morning and evening, only morning dose on Day 9)
