Brief summary: Single centre, open-label, randomised study in four parallel groups of healthy volunteers

Detailed description: Single centre, open-label, randomised study in four parallel groups of healthy volunteers: Group 1 = 900 mg of eslicarbazepine acetate (ESL, BIA 2-093); Group 2 = 450 mg of S-licarbazepine plus 450 mg of R-licarbazepine; Group 3 = 450 mg of S-licarbazepine; Group 4 = 450 mg of Rlicarbazepine. In each group, the study consisted of a single-dose period (Phase A) followed by a repeateddose period of 7 days of duration in which the investigational product was administered once daily (Phase B). The repeated-dose phase started 96 h post single-dose.
