Results of this review do not provide sufficient evidence in favour of anticonvulsants for the treatment of AWS. There are some suggestions that carbamazepine may actually be more effective in treating some aspects of alcohol withdrawal when compared to benzodiazepines, the current first-line regimen for alcohol withdrawal syndrome. Anticonvulsants seem to have limited side effects, although adverse effects are not rigorously reported in the analysed trials.
A pilot open randomized trial of valproate and phenobarbital in the treatment of acute alcohol withdrawal.
The authors conducted a randomized, open comparison of the GABAergic anticonvulsant sodium valproate (divalproex sodium; Depakote) and phenobarbital as an active control in the management of acute withdrawal from alcohol. Repeated measures ANOVA was used to assess treatment effects in the first 37 inpatients, evaluating mood, hostility, and subjective and objective measures of withdrawal at index, 3, and 5 days of detoxification. Subjective and objective ratings of abstinence symptoms and subjective mood disturbance decreased significantly in intensity in both groups over 5 days, but there were no significant treatment differences nor treatment by time interactions. Hostility scores did not differ overall, but a group by time effect was observed (F = 5.42, df = [1,13], P < 0.05), with phenobarbital subjects reporting less hostility/aggression than those in the valproate group. There were no withdrawal-related seizures or other acute sequelae. This study offers pilot confirmation that sodium valproate is as effective as phenobarbital in the management of acute alcohol withdrawal, but it is unclear whether valproate offers a clinical advantage with respect to stabilizing changes in mood and interpersonal hostility during detoxification.
