Brief summary: Single centre, open-label, multiple doses, one-sequence design study in two parallel groups of healthy volunteers

Detailed description: Single centre, open-label, multiple doses, one-sequence design study in two parallel groups of healthy volunteers: Group A: Pre-treatment with ESL, treatment with ESL and ascending doses of Lamotrigine (LMT) in last phases; Group B: Pre-treatment with LMT, treatment with LMT and ascending doses of ESL in last phases

Eligibility criteria: Inclusion Criteria:

* Availability of volunteer for the entire study period and willingness to adhere to protocol requirements as evidenced by the informed consent form (ICF) duly read, signed and dated by the volunteer
* Male aged of at least 18 years but not older than 45 rears with a body mass índex (BMI) greater than or equal to 19 and below 30 kg/m
* Clinical laboratory values within the laboratory's stated normal range; if not within this range, they must be without any clinical significance (laboratory tests are presented in section 6.1.1.3)
* Healthy according to the medical history, laboratory results and physical examination
* Light-, non- or ex-smokers. A light smoker is defined as someone smoking 1 0 cigarettes or less per day, and an ex-smoker is defined as someone who completely stopped smoking for at least 12 months before day I of thi s study The informed consent form must be signed by all volunteers, prior to their participation in the study.

Exclusion Criteria:

* Significant history of hypersensitivity to lamotrigine, eslicarbazepine, oxcarbazepine, carbamazepine or any related products (including excipients of the formulations) as well as severe hypersensitivity reactions (like angioedema) to any drugs
* Presence of significant gastrointestinal, liver or kidney disease, or any other conditions known to interfere with the absorption, distribution, metabolism or excretion of drugs or known to potentiate or predispose to undesired effects

* Presence or history of significant ocular disease
* Maintenance therapy with any drug, or significant history of drug dependency or alcohol abuse (\> 3 units of alcohol per day, intake of excessive alcohol, acute or chronic).
