Seizure Drug Reverses Cellular Effects In Brain Related To Alcohol

In the new research the scientists found that gabapentin normalizes the action of certain brain cells altered by chronic alcohol abuse in an area of the brain known as the central amygdala, which plays an important role in fear- and stress-related behaviors, as well as in regulating alcohol drinking. In the study, alcohol-dependent rodents receiving gabapentin drank less alcohol.

"The results are exciting," said Scripps Research Assistant Professor Marisa Roberto, Ph.D., who was first author of the study. "Our research shows that gabapentin not only changes the alcohol-consumption patterns of addicted rats (and not of the control group), but also may reverse some of the effects of addiction on a specific neurotransmitter in the brain."

"This is an example of the strength of the translational approach of the Pearson Center, where the clinical uses of gabapentin led us to hypothesize that gabapentin may act to restore homeostatic dysregulation of the GABAergic system," said George Koob, Ph.D., chair of the Scripps Research Committee on the Neurobiology of Addictive Disorders and co-director of the Pearson Center for Alcoholism and Addiction Research at Scripps Research.
