Oct. 9, 2007 -- The seizure and migraine medication Topamax shows promise
for treating alcohol dependence, a study shows. But use of the drug for this
purpose is not without controversy.
Alcohol-dependent patients in the University of Virginia study who took
Topamax for three and a half months averaged fewer heavy drinking days overall,
fewer drinks per day, and more days of continuous abstinence from drinking than
patients given placebo treatments.
The study was paid for by Topamax manufacturer Ortho-McNeil Neurologics, and
it appears in the Oct. 10 issue of TheJournal of the American
A spokeswoman for Ortho-McNeil tells WebMD that the company will not be
pursuing FDA approval for the drug as a treatment for alcohol dependence.

conditions, it is illegal for the companies that market the drugs to promote
these so-called "off label" uses.
The Public Citizen complaint involved a question-and-answer sheet
distributed to the media before publication of the study, which specifically
discussed the drug's potential "off label" use for alcohol

"Ortho-McNeil Neurologics does not support any reference to off label
use of its products and only promotes the use of Topamax in the approved
indication of migraine and epilepsy treatment," Russell says.

Fewer Drinks and Drinking Days
The study included 371 men and women with alcohol dependence. The men drank
35 or more standard alcoholic drinks per week prior to enrollment; the women
had 28 or more drinks. Participants' ages ranged from 18 to 65 with an average
of around 47.
A standard alcoholic drink was defined as one containing 0.5 ounces of
alcohol, which is found in a 10-ounce regular beer, a 4-ounce glass of wine, or
1 ounce of 100-proof liquor.
