Alcohol Abstinence Clinical Trial
Official title:
Guanfacine to Reduce Relapse Risk in Women With Alcohol Use Disorder (AUD)
Guanfacine may preferentially reduce craving and improve cognitive control in women with Alcohol Use Disorder (AUD), compared to men. As these behaviors are related to relapse, the objectives of this study are to conduct a 10-week out-patient clinical trial to examine the effects of Guanfacine Extended Release (XR; 3mgs) versus placebo on drinking measures in women with AUD.
Gender-specific variation in sympathetic sensitivity (Fox et al., 2014; Fox and Sinha, 2009; Cahill, 2003; Heinsbroek et al., 1991) may mean that guanfacine is particularly efficacious in attenuating drinking in women, rather than men with Alcohol Use Disorder (AUD). Thus, the investigators propose a double blind, placebo-controlled, 10-week randomized clinical trial to examine the effects of Guanfacine XR (3mgs/daily) versus placebo in 60 women with AUD. This will include twice weekly appointments comprising medical management and contingency management protocols, collection of urine, breathalyzer screens, and vitals. Measures of craving and mood will also be assessed. Parallel laboratory challenge studies will also be conducted both on admission to out-patient treatment and again following 4 weeks of treatment, in order to better elucidate the potentially therapeutic mechanisms of guanfacine. Participants will be exposed to a personal stress versus relaxing imagery condition, 1 condition per day, in a randomized order. Craving, anxiety, mood, cognitive control, heart rate and blood pressure (HRBP), and biological stress system markers will be assessed at baseline, following imagery and at various recovery timepoints. ;
