Official title

A Focus on Alpha-1 Blockade as a Novel Pharmacological Treatment for AUD

Overview

The goal of this research is to replicate findings previously conducted in a pilot trial and to understand, mechanistically, the role of stress in the development of AUD pharmacotherapies that target noradrenergic blockade.

Detailed description

16 week, between-subject, double-blind, randomized clinical trial (RCT) with doxazosin (16 mg, or maximum tolerated dose, MTD) compared to placebo in 184 treatment seeking individuals with AUD

Interventions

  • Drug Doxazosin
    16 mg or maximum tolerated dose (MTD)
  • Drug Placebo
    Matching placebo

Primary outcome measures

  • Alcohol consumption [Time frame: 6 weeks]
Secondary outcome measures (2)
  • Alcohol craving [Time frame: one day]
  • Alcohol craving [Time frame: six weeks]
