Washington: The drug topiramate, typically used to treat epilepsy and more recently weight loss, could also help people get rid of their cocaine and alcohol addictions, a new study has revealed.
Results from the double-blind, placebo-controlled trial adds to the growing body of evidence supporting topiramate as a promising medication to treat addiction.
Past, separate studies have shown that topiramate can reduce alcohol dependence, as well as reduce relapse to cocaine; however, its use to treat both alcohol and cocaine dependent people has not been explored in a clinical trial.
Cocaine and alcohol addictions often go hand in hand, so therapies targeting both may be the best strategy to treat individuals.
The research by the department of Psychiatry at Penn Medicine from the 13-week clinical trial of 170 alcohol and cocaine dependent people produced mixed results.
The drug reduced alcohol cravings, but did not reduce drinking, and was not better at reducing cocaine cravings.
Addicts on topiramate, however, versus those on a placebo were more likely to stay in treatment and abstain from cocaine during the last three weeks of the trial.
People with more severe cocaine withdrawal symptoms- agitation, restless behavior, and depressed mood-appeared to have benefited most from topiramate.
"Cocaine dependence continues to be a significant public health concern in the United States and Europe. Drug counseling remains the treatment of choice, but many patients do not respond completely to it, so developing effective medications for treatment is a research priority," first author Kyle M. Kampman, MD, professor of Psychiatry at the Perelman School of Medicine at the University of Pennsylvania, and medical director at the Charles O`Brien Center for Addiction Treatment, said.
"Based on the study`s results, this drug, plus cognitive behavioral therapy, may be a good option for people addicted to both alcohol and cocaine to help reduce their cocaine use," he said.
The study is published in the journal Drug and Alcohol Dependence.
