Inclusion criteria
* Subjects meeting all the following inclusion criteria at screening visit: 1. Healthy male or females subjects, 18-45 years (inclusive) of age at the time of enrollment. 2. Females must be of non-childbearing potential (i.e., surgically sterile) or have to use contraceptive measures (non-hormonal) such as condom, diaphragm or cervical/vault cap with spermicide until 28 days post-administration. Males should agree to abstain from sexual intercourse with a female partner or agree to use a condom with spermicide, in addition to having their female partner use some contraceptive measures until 28 days post-administration. 3. Clinically acceptable blood pressure and pulse rate in supine and standing position. Blood pressure and pulse will be measured after a minimum of 3 minutes of resting. 4. Body weight within normal range (Quetelet's index between 19 and 26) expressed as weight (kg) / height (m2). 5. Able to understand the nature of the study and comply with all their requirements. 6. Free acceptance to participate in the study by obtains signed informed consent form approved by the Ethics Committee of the Hospital (CEIC).
Exclusion criteria
* Subjects meeting any of the following criteria at screening visit will be excluded from entry into the study: 1. History of serious adverse reactions or hypersensitivity to any drug. 2. Presence or history of allergies requiring acute or chronic treatment (except seasonal allergic rhinitis). 3. Background or clinical evidence of chronic diseases. 4. Acute illness two weeks before drug administration. 5. Having undergone major surgery during the previous 6 months. 6. Smokers (refrained from any tobacco usage, including smokeless tobacco, nicotine patches, etc., for 6 months prior to the administration of the study medication. 7.

Abnormal physical findings of clinical significance at the screening examination or baseline which would interfere with the objectives of the study. 9. Need of any prescription medication within 14 days prior to the administration of the drug and non prescription medication or herbal medicines within 7 days prior to the administration of the drug. 10. Participation in other clinical trials during the previous 90 days in which an investigational drug or a commercially available drug was tested. 11. Having donated blood during 4 weeks period before inclusion in the study. 12. Existence of any surgical or medical condition which might interfere with the absortion, distribution, metabolism or excretion of the drug, i.e. impaired renal or hepatic function, diabetes mellitus, cardiovascular abnormalities, chronic symptoms of pronounced constipation or diarrhea or conditions associated with total or partial obstruction of the urinary tract. 13. 12 lead ECG obtained at screening with PR ≥ 220 msec, QRS ≥120 msec and QTc ≥ 440 msec, bradychardia (\<50 bpm) or clinically significant minor ST wave changes or any other abnormal changes on the screening ECG that would interfere with measurement of the QT interval. 14. Symptoms of a significant somatic or mental illness in the four week period preceding drug administration. 15. History of hepatitis HBV and / or HCV and / or positive serology results which indicate the presence of hepatitis B surface antigen and / or detectable HCV ribonucleic acid (RNA). 16.
