The purpose of this study is to evaluate whether the combination of prazosin and naltrexone will decrease alcohol cravings and drinking in individuals who have problems with alcohol and have used alcohol at risky levels compare to naltrexone and placebo (Nal/Pl), prazosin and placebo (Praz/Pl), and double-placebo (Pl/Pl). We hypothesize that those assigned to both prazosin and naltrexone would report significantly greater decreases in percent drinking days and heavy drinking days as well as significantly greater reduction in craving from pre to post-treatment than those assigned to either single medication or double-placebo. Prazosin is a medication that is approved by the U.S. Food and Drug Administration (FDA) to treat people with high blood pressure. Some studies have shown that prazosin may also decrease nightmares and improve sleep in Veterans suffering from Posttraumatic Stress Disorder (PTSD). Animal studies have consistently found that prazosin is associated with decreased alcohol consumption and that the combination of prazosin and naltrexone outperforms either medication alone. The current study is evaluating an "off-label" use of prazosin to determine whether it is helpful in decreasing alcohol cravings and consumption among people with alcohol problems. "Off-label" means that the FDA has not approved the use of prazosin for alcohol problems. Naltrexone is a medication that is FDA approved for treating alcohol problems. This study is sponsored by the Department of Defense and the Congressionally Directed Medical Research Program (DoD/CDMRP). We expect approximately 120 participants in this study, which will run over approximately 4 years. Study participants will be involved in the study for 7 weeks, or until they complete the Final Assessment.

---|---|---|---|---|
Primary | Change in Percent Drinking Days (PDD) (Visit 8 PDD - Visit 2 PDD) | PDD was calculated based on self-reported drinking history collected via Form-90. Drinking days were defined as days when participants consumed alcohol. Form-90 was completed by participants in visit 2 (baseline) and visit 8 (last visit). Form-90 collected in the baseline visit recorded participants' alcohol consumption from 90 days prior to their baseline visit until the day before their baseline visit. Form-90 collected in the last visit recorded participants' alcohol consumption from baseline until the day before their last visit. This outcome measures changes in PDD between visit 8 and visit 2. Per the protocol, visit 8 is scheduled to occur 42 days (± 7days) after visit 2. In reality, visit 8 occurred 35 to 76 days after visit 2 with the average of 45 days. The outliers were due to scheduling difficulties. | Visit 2 (baseline) and visit 8 (last visit). Per the protocol, visit 8 is scheduled to occur 42 days (± 7days) after visit 2. In reality, visit 8 occurred 35 to 76 days after visit 2 with the average of 45 days due to scheduling difficulties. | |
Primary | Change in Percent Heavy Drinking Days (PHDD) (Visit 8 PHDD - Visit 2 PHDD) | PHDD was calculated based on self-reported drinking history collected via Form-90. Heavy drinking days were defined as days when participants consumed 4 or more drinks for females and 5 or more drinks for males. Form-90 was completed by participants in the baseline and last visit. Form-90 collected in the baseline visit recorded participants' alcohol consumption 90 days prior to their baseline visit. Form-90 collected in the last visit recorded participants' alcohol consumption from baseline until the day before their last visit. This outcome measures changes in PHDD between visit 8 and visit 2. Per the protocol, visit 8 is scheduled to occur 42 days (± 7days) after visit 2. In reality, visit 8 occurred 35 to 76 days after visit 2 with the average of 45 days. The outliers were due to scheduling difficulties. | Visit 2 (baseline) and Visit 8 (last visit). Per the protocol, visit 8 is scheduled to occur 42 days (± 7days) after visit 2. In reality, visit 8 occurred 35 to 76 days after visit 2 with the average of 45 days due to scheduling difficulties. | |
Primary | Change in Alcohol Craving (Visit 8 PACS - Visit 2 PACS) | Alcohol craving was assessed in visit 2 (baseline) and the last visit (visit 8) using the Pennsylvania Alcohol Craving Scale (PACS). The PACS had 5 questions, where each question had six options presented in Likert Scales from 0 to 6, with 0 being the least and 6 being the highest possible option, thus the possible minimum and maximum values are 0 and 30, respectively. Higher scores mean higher craving. This outcome measures the change in PACS scores between visits 2 and 8 (visit 8 PACS score - visit 2 PACS score). Per the protocol, visit 8 is scheduled to occur 42 days (± 7days) after visit 2. In reality, visit 8 occurred 35 to 76 days after visit 2 with the average of 45 days. The outliers were due to scheduling difficulties. | Visit 2 (baseline) and visit 8 (last visit). Per the protocol, visit 8 is scheduled to occur 42 days (± 7days) after visit 2. In reality, visit 8 occurred 35 to 76 days after visit 2 with the average of 45 days due to scheduling difficulties. | |
Secondary | Change in Mean Drinks Per Day of Drinking (Visit 8 - Visit 2) | Average drinks per day of drinking was calculated based on self-reported drinking history collected via Form-90. Drinking days were defined as days when participants consumed alcohol. Form-90 was completed by participants in visit 2 (baseline) and visit 8 (last visit). Form-90 collected in the baseline visit recorded participants' alcohol consumption 90 days prior to their baseline visit. Form-90 collected in the last visit recorded participants' alcohol consumption from baseline until the day before their last visit. This outcome reports the change in the mean drinks between visit 8 and visit 2. Per the protocol, visit 8 is scheduled to occur 42 days (± 7days) after visit 2. In reality, visit 8 occurred 35 to 76 days after visit 2 with the average of 45 days. The outliers were due to scheduling difficulties. | Visit 2 (baseline) and visit 8 (last visit). Per the protocol, visit 8 is scheduled to occur 42 days (± 7days) after visit 2. In reality, visit 8 occurred 35 to 76 days after visit 2 with the average of 45 days due to scheduling difficulties. |
