Naltrexone Derivative Superior for Treating Alcoholism, Researchers SaySeptember 15, 2008
Research Summary
A modified version of the alcohol addiction medication naltrexone may be equally effective but without the unpleasant side-effects of the unadulterated drug, according to researchers from the University of California at San Francisco.
Scientific American reported Sept. 12 that rats given the new compound, SoRI-9409 consumed half as much alcohol and did not experience the withdrawal symptoms typical of naltrexone use. "It is much more selective in its effect on drinking," said researcher Selena Bartlett of the Ernest Gallo Clinic and Research Center.
The new compound also holds promise in ensuring prolonged abstinence from alcohol. "That is currently the biggest challenge in alcoholism treatment," Bartlett said.
Rats who were given the compound for 28 days continued to avoid heavy drinking for four weeks after they stopped taking the drug. "Drinking stays down without the drug in place," Bartlett said. "It's done something to permanently change and reduce the drinking."
The findings were published in the September 2008 issue of the journal Biological Psychiatry.
