The primary efficacy outcome for the trial was a binary outcome measure of zero heavy drinking days during the last 4 weeks (Weeks 22–25) of the maintenance phase of the trial. Heavy drinking days were defined as more than or equal to four standard drinks for females and more than or equal to five standard drinks per day for males. Patients taking gabapentin had better rates of abstinence and cessation of heavy drinking than those taking placebo. During the 12-week study, the 1,800-mg daily dose showed a substantially higher abstinence rate (17%) than either 900 mg (11%) or placebo (4%). Daily drinking was recorded, and percentage of disialo carbohydrate-deficient transferrin in the blood, a heavy drinking marker, was collected at baseline and monthly during treatment. Interventions: Gabapentin up to 1200 mg/d, orally, vs placebo along with 9 medical management visits (20 minutes each). Research shows that gabapentin may improve withdrawal symptoms, reduce heavy drinking and promote abstinence when compared to placebo. Higher doses (1800 mg per day) may be more beneficial. A combination of gabapentin and naltrexone may be better at preventing heavy drinking compared to naltrexone alone. But once gabapentin was stopped, the Oral naltrexone, an opioid antagonist, reduces return to heavy drinking, percentage of drinking days, and percentage of heavy-drinking days. Studies of oral naltrexone also show a nonsignificant Several studies have explored gabapentin's efficacy in reducing alcohol consumption and craving. A randomized, double-blind, placebo-controlled trial demonstrated that gabapentin significantly reduced the number of drinks per day and the percentage of heavy drinking days, while increasing the percentage of days of abstinence 2. The prestudy high–alcohol withdrawal group had positive gabapentin effects on no heavy drinking days (P < .02; NNT, 3.1) and total abstinence (P = .003; NNT, 2.7) compared with placebo, while within the low–alcohol withdrawal group, there were no significant differences. These findings were similar for other drinking variables, where Is gabapentin an effective treatment for alcohol use disorder (AUD)? Gabapentin treatment avoided more heavy drinking days (> 5 standard drinks/day) than placebo (27% vs 9%). Gabapentin can be a second-line, off-label option to treat AUD. However, there is mixed evidence and concerns about abuse-misuse, and drug-related harms. Some research shows that gabapentin has promise as an alcohol withdrawal treatment, possibly in combination with other medications. Gabapentin can: A clinical trial showed that people with Doctors don’t recommend drinking alcohol while taking gabapentin, especially for those who have just started taking it. However, you may talk to your doctor about drinking in moderation after you’ve reached a stable dose. strated the effectiveness and safety of gabapentin in reducing heavy-drinking days, particularly for those who self-reported more alcohol with-drawal symptoms. 12 Patients with AUD are at risk Gabapentin was associated with significant linear dose-related reductions in drinking quantity and frequency, GGT, alcohol craving, sleep and negative affect, as well as increased rates of abstinence and no heavy drinking over the 12-week study period. Gabapentin and topiramate (Topamax), though not approved for this use, may be considered as second-line treatments. 33 In a randomized controlled trial, patients who started taking gabapentin There was less relapse to heavy drinking (NNT, 3.1) and more total abstinence (NNT, 2.7) in those with more intense alcohol withdrawal symptoms treated with gabapentin, and we also found an interaction between the level of those symptoms on other continuous drinking outcomes, including percentage of heavy drinking days, percentage of days Gabapentin has shown efficacy in preventing relapse to heavy drinking, with a number needed to treat (NNT) of 5.4 for preventing relapse and 7.2 for promoting abstinence in individuals with alcohol use disorder (AUD) who have a history of alcohol withdrawal symptoms. Although gabapentin appears to be more efficacious than placebo in treating AUD, the only measure on which the analysis clearly favors the active medication is percent heavy drinking days. Additional studies are needed to define more clearly the role of gabapentin in AUD treatment. return to any drinking, return to heavy drinking, percent drinking days, and percent heavy drinking days at the 50 mg oral dose. Of note, the prior report found no benefit for injectable naltrexone, but the addition of a new randomized controlled trial conducted in a population experiencing homelessness resulted in positive outcomes for a During the first 6 weeks, the naltrexone-gabapentin group had a longer interval to heavy drinking than the naltrexone-alone group, which had an interval similar to that of the placebo group; had fewer heavy drinking days than the naltrexone-alone group, which in turn had more than the placebo group; and had fewer drinks per drinking day than the naltrexone-alone group and the placebo group. Previous studies of gabapentin and alcohol dependence was limited by small sample size, methodological issues, or dosing issues OBJECTIVE The main objective was to determine if gabapentin increases rates of sustained abstinence and no heavy drinking and decreases alcohol-related insomnia, dysphoria and craving, in a dose-dependent manner.
