Effects of Omegas 3 and 6 on Alcohol Dependence

Phase 3

Completed

Interventions: Drug: PUFAs
Drug: Placebo
Drug: Naltrexone + Placebo
Drug: Naltrexone

Brief Summary: Context: The treatment of alcoholism is a challenge for psychiatrists and patients. Some studies have shown that alcohol alters the environment of the membranes, mainly by modifying their permeability through the lipid fraction. These lipids are known as essential fatty acids (EFA) because they are obtained only through the diet, as the human body is unable to synthesize them. Linolenic acid (LA), or omega 6, and alpha-linolenic acid (ALA), or omega 3, are polyunsaturated fatty acids (PUFAs). Finally, ethanol changes the absorption and metabolism of PUFAs, and it's supplementation may be helpful for alcohol dependence recovery.

Objective: to assess the effectiveness of PUFAs supplementation in the treatment of alcohol dependent patients.

Primary Outcome Measures

Name	Time	Method
"Drinking Days" in the Previous Month	3 months	The Alcohol Timeline Followback (TLFB) is a drinking assessment method that obtains estimates of daily drinking and has been evaluated with clinical and nonclinical populations. Using a calendar, people provide retrospective estimates of their daily drinking over a specified time period that can vary up to 12 months from the interview date.

Secondary Outcome Measures

Name	Time	Method
Short Alcohol Dependence Data Questionnaire (SADD)	3 months	The Short Alcohol Dependence Data is a self-completion questionnaire designed to evaluate the presence and the degree of severity of alcohol dependence and consists of 15 questions. The minimum and maximum scores possible are 0 and 45 points respectively. The range of 1-9 is considered as low dependence, 10-19 medium dependence and 20 or more high dependence.
Obsessive Compulsive Drinking Scale (OCDS)	3 months	The Obsessive Compulsive Drinking Scale (OCDS) is consisted by 14 items rated 0 - 4. The minimum and maximum values possibly obtained in this scale are respectively 0 and 56, this last one, meaning the most craving possible experienced. It is a short and easy to administer scale (average of 5 minutes per self-rating), built to measure severity and improvement during alcoholism treatment trials.
