The current "gold-standard" for the management of alcohol withdrawal syndrome (AWS) is symptom-triggered administration of benzodiazepines. This method of treatment has several drawbacks that have been described in the literature. Thus benzodiazepine sparing agents have been evaluated for use in AWS. One of these agents that has not only shown benefit for AWS but also benefits on complete abstinence, reducing a return to heavy drinking, and cravings is gabapentin. In clinical practice at Mayo Clinic gabapentin is used for this purpose. Due to the limited reports of the safety and efficacy of a protocol involving gabapentin for AWS, a study to compare gabapentin to symptom-triggered lorazepam will be completed.
The current "gold-standard" for the management of alcohol withdrawal syndrome is symptom-triggered administration of benzodiazepines. Benzodiazepines and use of a symptom-triggered approach has several drawbacks such as over administration of medication due to many subjective patient reported symptoms. Benzodiazepines may contribute to a drug-induced delirium or high dosage may necessitate transfer to an ICU setting. Abrupt withdrawal of benzodiazepines also contribute to cravings, rebound insomnia, and anxiety that have been shown to increase the risk of a return drinking. Clinical use of gabapentin for alcohol withdrawal has been presented by Maldonado at Stanford University Hospitals. (Academy of Psychosomatic Medicine Annual Meeting, 2013-2015) At Mayo Clinic, the Psychiatry Consultation-Liaison hospital service has been recommending the use of a modified gabapentin protocol since January 2015, which has been clinically accepted on medical, surgical, and psychiatric hospital services. The purpose of this research is to investigate the reactive benzodiazepine versus proactive gabapentin approaches to AWS in a prospective, randomized, open-label study.

Mean Length of Hospital Stay
The length of hospital stay for Alcohol withdrawal syndrome. The time interval between admission and either discharge or the time at which Clinical Institute Withdrawal Assessment - Alcohol revised (CIWA-Ar) scores are \<10 for 36 hours (up to 240 hours). Measured in hours. CIWA-Ar measures severity of 10 observed or measured alcohol withdrawal signs or symptoms. Zero to 7 points are assigned to each item, except for the last item, which is assigned 0-4 points, with a total possible score of 67. Total score ranges from 0 (best possible outcome)-67 (worst possible outcome). Lower scores (0-8) represent fewer withdrawal symptoms and less severity, scores \> 8 represent more withdrawal symptoms and greater severity
Time frame: Time to discharge or time to CIWA-Ar score < 10 for 36 hours (whichever came first) up to 240 hrs.
Number of Participants With Delirium Tremens (DT)
The number of participants experiencing delirium tremens during their hospitalization (between admission and discharge).
Time frame: During hospitalization (up to 240 hours)
Maximun Alcohol Withdrawal Severity Per CIWA-Ar Scale
CIWA-Ar measures severity of 10 observed or measured alcohol withdrawal signs or symptoms. Zero to 7 points are assigned to each item, except for the last item, which is assigned 0-4 points, with a total possible score of 67. Total score ranges from 0 (best possible outcome)-67 (worst possible outcome). Lower scores (0-8) represent fewer withdrawal symptoms and less severity, scores \> 8 represent more withdrawal symptoms and greater severity
Time frame: 4 days
Change in Sleepiness as Assessed by the Epworth Sleepiness Scale
The ESS is a self-administered questionnaire with 8 questions. Respondents are asked to rate, on a 4-point scale (0-3), their usual chances of dozing off or falling asleep while engaged in eight different activities. Most people engage in those activities at least occasionally, although not necessarily every day. The ESS score (the sum of 8 item scores, 0-3) can range from 0 to 24. The higher the ESS score, the higher that person's average sleep propensity in daily life (ASP), or their daytime sleepiness.
Time frame: Baseline and 2 days
Mean Total Benzodiazepine Use
The total amount of benzodiazepines administered. Measured by lorazepam equivalent, mg.
Time frame: Time to discharge or time to CIWA-Ar score < 10 for 36 hours (whichever came first) up to 240 hrs.
Number of Participants Experiencing Seizure
The number of subjects who developed seizure during their hospitalization.
Time frame: During hospitalization (up to 240 hours).
Change in Cravings as Assessed by the Penn Alcohol Craving (PACS) Scale
PACS is a 5 item self-rated scale of alcohol craving (0 = none to 6 = strong urge). Total scores range from 0 (little craving for alcohol) to 30 (irresistible urge to drink alcohol)
Time frame: Baseline and 2 days
Change in Anxiety Symptoms as Measured by the Generalized Anxiety Disorder-7 (GAD-7) Scale
GAD-7 is GAD-7 is a 7-item self-administered scale of Generalized Anxiety Disorder symptoms (0 = not at all to 3 = nearly every day). Total scores range from 0 to 21. Total scores of 0-4 = minimal anxiety, Total scores of 5-9 = mild anxiety, total scores of 10-14 = moderate anxiety and total scores of 15-21 = severe anxiety.
Time frame: Baseline and 2 days
