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.
Double-blind controlled trial of bromocriptine, chlordiazepoxide and chlormethiazole for alcohol withdrawal symptoms.
Seventy-one patients undergoing withdrawal from alcohol were randomly assigned to treatment with oral bromocriptine, chlormethiazole or chlordiazepoxide. Forty-one percent had alcoholic hepatitis and/or cirrhosis. Patients were stratified into two groups: major and minor withdrawal symptoms. The latter group included a placebo tratment. Bromocriptine was ineffective in treating withdrawal symptoms, whilst chlormethiazole and chlordiazepoxide were equally effective. These findings do not support the evidence from animal and clinical studies suggesting that the disturbances in the dopaminergic system found in alcohol dependence and withdrawal can be reversed by dopamine agonists.
