Rats can’t get drunk after a dose of oxytocin hormone

The so-called "cuddle-chemical" seems to block the action of alcohol in the brain, preventing the tell-tale signs of drunkenness in rats

CHEERS! If you want to counteract the effects of getting drunk, a shot of the “cuddle chemical” oxytocin might be the answer.

Oxytocin plays a role in sexual behaviour and social bonding. While investigating the chemical’s known effect on alcohol cravings, Michael Bowen from the University of Sydney, Australia, noticed something strange – rats given a dose of it didn’t seem to get drunk.

“Those that had the oxytocin were up and moving about as if they hadn’t had any alcohol at all, whereas the ones that didn’t have oxytocin were quite heavily sedated,” Bowen says.

The chemical appears to counteract alcohol by binding to GABA receptors in the brain, the same ones on which alcohol exerts its intoxicating effects (PNAS, ). Bowen hopes his findings will lead to a drug that doesn’t just prevent drunkenness, but also helps alcoholics cope with withdrawal.

However, the effects in rats weren’t limitless. While oxytocin prevented drunkenness in those that had been given the equivalent of a bottle and a half of wine, its effects did not extend as far as the rat-sized equivalent of a whole bottle of vodka.
