SECONDARY outcome

Timeframe: Every 2-4 hours for 24 hours after starting study drug

Proportion of clinical institute withdrawal assessment (CIWA) Scores listed as severe or moderate 24 Hours after Starting Study Drug. All subjects had at least four CIWA assessments.The CIWA is a ten item scale with each item on the scale scored independently on a 0-7 or 0-4 scale, and the summation of the scores yielding an aggregate value that correlates to the severity of alcohol withdrawal. Ranges of scores are from 0 to 67. Mild alcohol withdrawal is defined with a score less than or equal to 15, moderate with scores of 16 to 20, and severe with any score greater than 20. The ten items evaluated include nausea and vomiting, tremor, sweats, anxiety, agitation, tactile disturbances, auditory disturbances, visual disturbances, headache, and orientation.
