 The study will explore the efficacy and tolerability of a 12-week regimen of 10 mg t.i.d. baclofen vs. placebo in conjunction with behavioral therapy for reducing heavy drinking in 80 alcohol dependent individuals. Prior studies Addolorato et al. 2000, 2002; Flannery et al., 2004 have found that baclofen reduces self-reported anxiety and craving; therefore, the proposed study also will assess baclofens ability to reduce symptoms of these affective states. Furthermore, in our pilot study Flannery et al, 2004, women appeared to respond more consistently than men, and therefore the study will also be balanced by gender.
