Recent advances in the understanding of the neurobiological basis of a
lcohol dependence have led to the development of pharmacological agent
s for the treatment of drinking problems. However, alcoholism is a com
plex disease with psychological and social dimensions in addition to m
edical problems. This implies that, in this domain, pharmacotherapy mu
st be integrated in a general strategy of treatment and directed to sp
ecific aspects of management of the disease, such as treatment or prev
ention of the withdrawal syndrome or prevention of relapse after detox
ification. Whereas the treatment of the withdrawal syndrome with pharm
acological agents such as the benzodiazepines is now an established pr
actice, the use of drugs for other dimensions of the disease is more c
ontroversial. However, the pharmacological approach aimed towards prev
ention of relapse appears promising, by means of classical medications
such as disulfiram or new drugs (e.g. opiate antagonists and acampros
ate). The clinical evaluation of such medications requires guidelines
that will permit extrapolation of the results of the trials to situati
ons that are commonly faced by practitioners.
