A Double Blind Evaluation of Flumazenil and Gabapentin for the Treatment of Alcohol Withdrawal and Relapse Prevention
In Brief
A Phase 3 clinical trial evaluating Flumazenil and Gabapentin and Placebo for Alcohol Dependence. Completed, enrolled 60 participants across 1 site.
Detailed Summary
This is a placebo controlled trial (some people receive active and some people receive inactive medication) to evaluate the effectiveness of a new protocol to treat alcohol dependence. Two main medications (plus ancillary non-placebo controlled medications) and their placebos (inactive drugs) will be utilized to treat both alcohol withdrawal, promote abstinence, and reduce drinking over approximately a six-week treatment period. All participants will meet criteria for Alcohol Dependence and be drinking heavily up until 72 hours prior to receiving the first study drug. They will be injected one drug (flumazenil or placebo) over a two day period and receive the second one (gabapentin or placebo) by mouth for 39 days. The main hypothesis is that this protocol will reduce early alcohol withdrawal symptoms and will reduce relapse to drinking and promote abstinence compared to the placebo (inactive) drug group. Secondary outcomes that will be evaluated include reduction in craving, improvement in sleep, brain activity and mood.
