Acamprosate Treatment: Mechanisms of Action - Full Text View

Purpose

This study will examine whether pretreatment with two doses of acamprosate for seven days prior to abstinence lessens the intensity of acute withdrawal from alcohol compared with a placebo. Subjects will be randomly assigned to receive either one of two doses of acamprosate or placebo for seven days. This will be followed by a four- day inpatient period when withdrawal will be monitored. Additional drinking information will be obtained at a three month followup interview.
