Swedish researchers have taken steps to develop a efficient drug to fight alcoholism by tweaking the brain’s reward system.
A dopamine stabiliser reduces alcohol cravings in humans and normalises the reward system in rats’ brains, according to two separate studies carried out by scholars at Karolinska Institute.
“The socio economic costs of alcohol are huge, not to mention the human suffering. It is inspiring to continue working,” Pia Steensland, an associate professor at the university, said in a statement.
“The results of our studies are promising, but there is still a long way to go before we have a marketable drug,” Steensland informed Xinhua.
Alcohol triggers the human brain to release more dopamine and create a euphoric sensation, although the pleasant effects wear off over time.
The study on humans showed that alcohol-dependent patients who had taken the dopamine stabilizer showed less of a desire to continue drinking after one glass of beer.
“Those with the poorest impulse control, that is those thought to be most at risk of relapse after a period of abstinence, were those who responded best,” Steensland said.
The other study showed that the substance could regulate the dopamine levels in rats who had consumed alcohol, suggesting that it might help stabilize the brain’s reward system in alcoholic patients.
