Inclusion Criteria:

• Signed and dated informed consent.
• Outpatients (not hospitalized by the moment of randomization).
• Average alcohol consumption during 30 days prior to screening higher than a medium drinking risk level (men: > 4 drinks/day or 14 drinks/week; women > 3 drinks/day or 7 drinks/week) according to the National Institute on Alcohol Abuse and Alcoholism (NIAAA) criteria.
• Patients diagnosed with alcohol dependence according to the International Classification of Diseases (ICD)-10, assessed with the Mini-International Neuropsychiatric Interview (MINI).
• Abstaining from alcohol during 3 days prior to screening and 3 days before randomization confirmed by the test for alcohol in exhaled air (less than 0,02 %).

• Anxiety or depressive disorder present at enrollment into the study. Montgomery-Asberg Depression Rating Scale (MADRS) score higher than 15.
• High suicidal risk confirmed by MINI.
• Previous use of opioid antagonists implants less than 3 months prior to screening; use of long-acting naltrexone injections (e,g, Vivitrol) less than 4 weeks after the first injection and 3 months after the second and the following injections; use of cyanamide (Kolme) less than 2 weeks prior to screening, use of oral opioid antagonists or disulfiram during 2 weeks prior to screening.
• Psychotherapeutic "coding" (a method when the patient is induced a misbelief that alcohol consumption would lead to death, expected to result from undisclosed pharmacological manipulation) that took place during less than 3 months prior to screening.
• Use of psychotropic medication less than 3 weeks before the screening (for long-acting and 'depot' formulations) or 1 week before the screening (for other formulations) except for those used to treat alcohol withdrawal syndrome.
• Severe alcohol withdrawal syndrome (severity of alcohol withdrawal more than 10 on Clinical Institute Withdrawal Assessment of Alcohol (CIWA-Ar) scale).
• History of seizures (excepting febrile seizers). Severe brain injury, history of intracranial neoplasms and/or intracranial haemorrhages or any conditions that impose the risk of seizures. History of anticonvulsive therapy.
• Any clinical condition affecting cognitive or other psychoneurological functioning (verified for head injury with the loss of consciousness that lasted more than 1 hour, or resulted in cognitive or behavioral impairment, stroke, encephalopathy, dementia, neurodegenerative disorder, etc). Except for mild cognitive impairment.
• Mental retardation of syndromes of severe organic brain injury.
• Use of drugs of abuse (opioids, cannabinoids, amphetamines, etc.) or diagnoses of substance addiction/dependence at the moment of screening or positive urine drug screen test.
• Significant liver function impairment (aspartate aminotransferase (AST) and alanine aminotransferase (ALT) higher than 3 upper limits of normal range or diagnosis of hepatic failure, class B or C by Child Pugh).
• Severe renal failure (creatinine clearance calculated at the screening less than 30 ml/min or renal replacement therapy).
• Severe cardiovascular system disorders: unstable angina, poorly controlled arrhythmia, cardiac failure of III or IV class by New-York Heart Association (NYHA), acute myocardial infarction within the past 6 months.
• HIV-infection, hepatitis B or C.
• Decompensated diabetes mellitus (determined glycated hemoglobin HbAc1 level more than 7,5%)
• Other concomitant disorders and conditions that, as per investigator's opinion, put the patient's safety under risk or that could affect the analysis of safety data.
• Any diagnosed or suspected malignancy.
• Pregnancy, breast feeding.
• Participation in any other clinical study during 30 days or 6 periods of half life (depending on what is longer) prior to screening.
