Double-blind controlled trial of gamma-hydroxybutyrate and clomethiazole in the treatment of alcohol withdrawal.

The aim of this double-blind, comparative study was to assess the efficacy and safety of gamma-hydroxybutyrate (GHB) in ameliorating the symptoms of alcohol withdrawal. Newly admitted alcohol-dependent patients (n = 98) were randomized to receive either clomethiazole 1000 mg daily (CLO group) (n = 33), or 50 mg GHB/kg body wt (n = 33) or 100 mg GHB/kg body wt (n = 32). This dose was administered for 5 days, halved on day 6, and on days 7 and 8 only placebo was given.
