We report on the effectiveness and safety of gamma-hydroxybutyric acid in t
he therapy of overt alcohol withdrawal syndromes, their prevention, and the
prevention of relapses in formerly detoxified alcoholics. We studied 321 p
atients (236 men, 85 women), divided into two open-study groups for the tre
atment and prevention of alcohol withdrawal syndromes and one double-blind
study group to evaluate the effects of gamma-hydroxybutyric acid versus pla
cebo on alcoholic craving and relapses in detoxified patients. Gamma-hydrox
ybutyric acid treatment promptly reduced withdrawal symptoms in all patient
s and prevented alcohol withdrawal syndromes in 55% of cases. The attenuati
on of craving in detoxified patients was significantly greater in the gamma
-hydroxybutyric acid-treated group in comparison with the placebo-treated g
roup. The therapeutic use of gamma-hydroxybutyric acid was not accompanied
by serious side effects. Gamma-hydroxybutyric acid diversion was poorly rep
resented: gamma-hydroxybutyric acid-induced abuse was reported in 4 (1.1%)
of 345 treated patients, and only 9 cases of gamma-hydroxybutyric acid acut
e poisoning were reported in the years 1992-1995. Our results suggest that
gamma-hydroxybutyric acid, with a favorable risk/benefit ratio, is a clinic
ally useful drug in the treatment of alcohol dependence. (C) 2000 Elsevier
