Brief summary
To investigate the pharmacokinetics of a single 900 mg oral dose of BIA 2-093 and a single 900 mg oral dose of Oxcarbazepine in healthy volunteers and to assess the tolerability of a single 900 mg dose of BIA 2-093 and Oxcarbazepine.
Detailed description
Single centre, open label, balanced randomised, two-way crossover study in 12 healthy volunteers. The study consisted of 2 periods separated by a washout period of 7 days or more. On each of the study periods the volunteers received either a single 900 mg oral dose of BIA 2-093 or a single 900 mg oral dose of Oxcarbazepine.
Interventions
Tablets containing BIA 2-093 in doses of 300 and 600 mg
Tablets containing 300 mg and 600 mg of Trileptal®
