A new medication that targets part of the brain’s stress system may help reduce alcohol use in people with alcohol use disorder (AUD), according to a new study. Researchers led by Raye Litten, from US National Institute on Alcohol Abuse and Alcoholism (NIAAA), conducted a randomised clinical trial of a new compound, called ABT-436, designed to block the effects of vasopressin, a neuropeptide produced in the hypothalamus of the brain.

“Vasopressin helps to regulate the pituitary adrenal axis and other brain circuits involved in emotion. As such, it plays a role in regulating stress, anxiety, and their interaction with AUD,” said Litten.

Litten and colleagues recruited 144 alcohol-dependent adult men and women for the 12-week study. During a 28-day baseline period, female participants consumed at least 28 drinks per week, while male participants consumed at least 35 drinks per week. Participants were then randomised to receive either placebo tablets or ones containing the ABT-436 compound.

Researchers monitored participants’ alcohol consumption, as well as their mood changes and smoking habits, as these are known to co-vary with alcohol consumption. They found that participants receiving ABT-436 experienced more days of alcohol abstinence than those receiving the placebo. In particular, participants who reported high levels of stress appeared to respond better to ABT-436, in that both the frequency of their drinking and the number of heavy drinking days they experienced decreased.

“Our findings suggest that potential future studies with drugs targeting vasopressin blockade should focus on populations of people with AUD who also report high levels of stress,” said first author Megan Ryan, a clinical project manager in the NIAAA Division of Medications Development.

Smokers may be another population that could benefit from ABT-436. In addition to its effects on alcohol consumption, study participants receiving the new compound experienced a reduction in smoking, researchers said. They suspect that ABT-436 might be targeting the same areas in the brain that relate to withdrawal and stress, and, in the process, influencing both tobacco and alcohol use disorders. The research was published in the journal Neuropsychopharmacology.
