Prophylactic treatment of alcoholism by lithium carbonate. A controlled study.

Lithium therapy has been shown to have a therapeutic influence in reducing the drinking and incapacity by alcohol in depressive alcoholics in a prospective double-blind placebo-controlled trial conducted over one year, but it had no significant effect on non-depressed patients. Patients in the trial treated by placebo had significantly greater alcoholic morbidity if they were depressive than if they were non-depressive.
