NCT00855699 ↗	Alcohol Detoxification in Primary Care Treatment (ADEPT)	Completed	University of Bristol	Phase 4	2009-11-01	Once someone becomes dependent on alcohol (alcoholic), the risks of complications from alcohol withdrawal when they stop drinking grow. These can include a life-threatening fit or delirium tremens (see things, become frightened). To prevent such complications, people take medication such as benzodiazepines (e.g., valium or librium) in reducing doses for about a week; this is called detoxification or 'detox.' In the UK effective alcohol treatment exists but little is known about what is the best detox medication. Alternative drugs to benzodiazepines appear to protect the brain from the toxicity of alcohol withdrawal and to reduce the likelihood of drinking again. This study will examine the feasibility of comparing medication regimens for alcohol detox for the first time in primary care. It will include a standard detox regimen (librium over 8 days) alone and together with a drug, acamprosate, that has been shown to reduce toxicity of alcohol withdrawal in preclinical models and is used after detox to help people remain sober. It will focus on the practicalities of doing such a study as well as assessing how people feel (withdrawal symptoms) and do (drinking during first month).
NCT01573052 ↗	Gabapentin vs Chlordiazepoxide for Ambulatory Alcohol Withdrawal	Completed	VA Salt Lake City Health Care System	Phase 4	2004-03-01	A randomized, double-blind controlled trial comparing treatment outcomes between chlordiazepoxide, or gabapentin to treat alcohol withdrawal syndrome in alcohol dependent veteran subjects. The objective of this trial is to compare the safety and effectiveness of these two medications. Intervention is a fixed dose taper of chlordiazepoxide, or gabapentin over 6 days. Subjects will be evaluated for 7-10 days to monitor alcohol abstinence, withdrawal severity scores, adverse events including ataxia, sedation, cognitive function and alcohol craving.
