Eligibility Criteria

• Age: 18 Years - 55 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Healthy male and female subjects, 18 to 55 years of age (inclusive) at screening.
• Body mass index (BMI) between 18.5 and 30 kg/m2 (both inclusive).
• Body weight not less than 50 kg.
• Medical history, vital signs, physical examination, standard 12-lead electrocardiogram (ECG) and laboratory investigations must be clinically acceptable or within laboratory reference ranges for the relevant laboratory tests, unless the investigator considers the deviation to be irrelevant for the purpose of the study.
• Non smokers or mild to moderate smokers (≤ 10 cigarettes or pipes per day).
• Females, if:
• Not of childbearing potential, e.g., has been surgically sterilized, undergone a hysterectomy, amenorrhea for ≥ 12 months and considered post-menopausal, Note: In postmenopausal women, the value of the serum pregnancy test may be slightly increased. This test will be repeated to confirm the results. If there is no increase indicative of pregnancy, the female will be included in the study.
• Of childbearing potential, the following conditions are to be met: Negative pregnancy test. If this test is positive, the subject will be excluded from the study. In the rare circumstance that a pregnancy is discovered after the subject received IMP, every attempt must be made to follow her to term.
• Not lactating. Abstaining from sexual activity (if this is the usual lifestyle of the subject) or must agree to use an accepted method of contraception, and agree to continue with the same method throughout the study.
• Examples of reliable methods of contraception include non hormonal intrauterine device and barrier methods combined with an additional contraceptive method.
• In this study the concomitant use of hormonal contraceptives is NOT allowed. Other methods, if considered by the investigator as reliable, will be accepted (after discussion with sponsor medical monitor).
• Males must agree to use an accepted method of contraception with a pregnant partner or partner of childbearing potential (barrier methods combined with an additional contraceptive method, true abstinence or vasectomy) throughout the study and refrain from donating sperm throughout the study.
• Written consent given for participation in the study before any study-specific screening procedure is performed.

You may not qualify if:

• Evidence of psychiatric disorder, antagonistic personality, poor motivation, emotional or intellectual problems likely to limit the validity of consent to participate in the study or limit the ability to comply with protocol requirements.
• Current alcohol use \> 21 units of alcohol per week for males and \> 14 units of alcohol per week for females. One unit (10 g alcohol) is equal to beer \[330 mL\], wine \[200 mL\], or distilled spirits \[25 mL\] per day.
• Regular exposure to substances of abuse or a history of alcoholism within 1 year prior to the first dose of IMP.
• Use of any medication, prescribed or over-the-counter or herbal remedies, within 2 weeks before the first administration of IMP except if this will not affect the outcome of the study in the opinion of the investigator. In this study the concomitant use of hormonal contraceptives is NOT allowed.
• Participation in another study with an experimental drug, where the last administration of the previous IMP was within 8 weeks (or within 5 elimination half-lives for chemical entities or 2 elimination half-lives for antibodies or insulin), whichever is the longer, before administration of IMP in this study, at the discretion of the investigator.
• Treatment within the previous 3 months before the first administration of IMP with any drug with a well-defined potential for adversely affecting a major organ or system.
• A major illness during the 3 months before commencement of the screening period.
• History of relevant hypersensitivity or allergy to any drug (including known hypersensitivity to the IMP, its excipients or to other carboxamide derivatives (e.g., carbamazepine, oxcarbazepine).
• History of bronchial asthma or any other bronchospastic disease.
• History of convulsions.
• History of porphyria.
• Relevant history or laboratory or clinical findings indicative of acute or chronic disease, likely to influence study outcome. The IMP is contraindicated in second or third degree atrioventricular block.
• Donation or loss of blood equal to or exceeding 500 mL during the 8 weeks before the first administration of IMP or received any blood or blood products.
• Diagnosis of hypotension made during the screening period. Supine systolic blood pressure should be at least 90/140 mmHg and diastolic BP 50/90 mmHg.
• Diagnosis of hypertension made during the screening period or current uncontrolled of hypertension.
