During the past decade, renewed interest in medications to prevent relapse
in alcoholics has yielded a number of promising candidates. Although two of
these medications, naltrexone and acamprosate, are currently in clinical u
se in a number of countries, overall, their effectiveness appears to be lim
ited. Disulfiram, the deterrent medication that was approved 50 years ago f
or the treatment of alcoholism, has not consistently been shown to be effic
acious. However, since inadequate dosing and other modifiable factors may l
imit its deterrent effects, the identification of a more potent metabolite
of disulfiram appears to warrant further evaluation. Studies of serotonergi
c agonists for treatment of alcoholism have also yielded inconsistent resul
ts. There is evidence, however, that subgroups of alcoholics may respond we
ll to such medications, suggesting that treatment matching may enhance thei
r efficacy. In addition, nalmefene, a compound with effects similar to nalt
rexone, as well as a sustained release formulation of naltrexone, may enhan
ce the beneficial effects of opioid antagonist therapy. Despite these devel
opments, much remains to be learned about the pharmacotherapy of alcoholism
. The ongoing development and evaluation of novel medications should be giv
en a high priority. However, such basic issues as; the optimal dosing strat
egy and duration of treatment for existing therapies are not known. Similar
ly, combination therapy, involving either multiple medications or the combi
nation of medication with specific psychotherapies, has not been well studi
ed. The utility of specific pharmacotherapies in women, different ethnic/ra
cial groups, adolescent and geriatric patients, and individuals with co-mor
bid alcohol and drug use disorders (including nicotine dependence) is also
largely unknown, as is the appropriateness of medication therapy for treatm
ent of early problem drinkers. The ultimate aim of these efforts is the dev
elopment of algorithms for the pharmacological treatment of heavy drinking,
which incorporate the characteristics of the patient and of pharmacologica
l and psychosocial treatments with demonstrated efficacy. Although a genera
l framework for such an effort currently exists, much detail is needed befo
re it will be of widespread clinical value.
