Drug Therapy for Alcohol Detoxification

Study Overview
=================
Brief Summary
-----------------
This project will provide relevant clinical information for primary care practitioners treating alcohol withdrawal syndrome in outpatient settings. This double-blind, placebo- controlled clinical trial will compare the effectiveness of lorazepam (Ativan) and carbamazepine (Tegretol) in alcoholics who meet the criteria for a diagnosis of uncomplicated alcohol withdrawal syndrome. Participants are randomized to five days of treatment with a 1-week posttreatment followup.

High white blood count, or liver function test that is 3 times higher than normal. Known hypersensitivity or previous adverse reaction to carbamazepine, lorazepam, or other benzodiazepines. Any relevant ECG abnormality which might require hospitalization or greatly interfere with safety during outpatient withdrawal. History of severe gastrointestinal (GI) disease which might render absorption of the medication difficult or produce medical instability of the patient during detoxification which would include active peptic ulcer disease, ulcerative colitis, regional ileitis, or evidence by history or physical examination of GI bleeding. Familial tremor or other neurological condition, determined by history, known to produce tremor. Unable to provide a written informed consent.
