Despite the success of psychosocial interventions such as Alcoholics Anonymous, chronic alcohol abuse remains a significant public health problem. Noting that stress is a relapse trigger in alcoholism, George et al. explored whether pharmacological inhibition of the neurokinin 1 receptor (NK1R), a mediator of the brain’s stress response, would alleviate symptoms associated with alcohol dependence. Mice genetically deficient in NK1R consumed less alcohol than controls. A drug that antagonizes NK1R was used in a small, controlled study of recently detoxified alcoholic inpatients and showed promising activity, such as reducing alcohol cravings. However, these latter results need to be confirmed in much larger, longer-term studies.
