Abstract
Sixty‐three mainly male alcoholics were randomly assigned to placebo or lofexidine treatment for 48 hr shortly after admission to the hospital. Their starting points were similar regarding their semiquantitative estimates of alcohol withdrawal symptoms (AWS). Their demographics, histories of past alcohol use, physical findings, and laboratory abnormalities usually associated with alcoholism were similar. Starting 3 hr after 0.4 mg of oral lofexidine, which was given every 6 hr as eight doses, the AWS scores were significantly lower than those of the placebo group. Hypotension was the strongest finding. Six placebo recipients had to be prematurely interrupted due to increasing or intolerable alcohol withdrawal symptoms and switched to a benzodiazepine. Only one lofexidine recipient was prematurely interrupted, due to transient hallucinations. The study has a large placebo effect both groups of patients rated the treatment process very highly. Lofexidine, an α2‐adrenergic agonist, was superior to placebo in alcohol withdrawal. This drug, as with its analogue donidine, may represent a new and important pharmacological treatment for alcohol withdrawal symptoms.
