Summary
To test the preliminary efficacy of 16.0 mg of Prazosin daily versus placebo in treatment seeking alcohol dependent individuals. This proposal is a laboratory and treatment outcome study to examine the effects of Prazosin on brief exposure to stress, drug cues and neutral situations on alcohol and drug craving, mood and neurobiological reactivity in a sample of cocaine and/or alcohol dependent individuals. Prazosin will be beneficial for reduction in stress and alcohol cue induced craving and related arousal. In a sample of treatment-seeking alcohol dependent men and women, we propose to examine (a) differences in measures of alcohol craving, emotion state, hypothalamic-pituitary-adrenal (HPA) activation, physiological arousal and plasma catecholamine response to stress imagery and to alcohol cue imagery as compared to neutral imagery; (b) reduction in alcohol abstinence symptoms; and (c) improvement in alcohol treatment outcomes as measured by reductions in heavy drinking days, any drinking days, secondarily on drinks/day, anxiety, mood and sleep.
