Abstract

Nitrous oxide (N 2 O) has been reported to reduce post-withdrawal craving in alcoholic humans, aiding in their continued abstinence. This article assessed the ability of N 2 O to suppress alcohol drinking in genetically selected high alcohol-drinking (HAD) and alcohol-preferring (P) rats. Although water was available ad libitum , they were accustomed to a limited access (1 h/day) choice between 10% ethanol (EtOH) and water. When drinking stabilized, the rats were exposed for 30, 60, or 120 min to a mixture of N 2 O and pure oxygen, timed to end 1 h before the limited access. N 2 O suppressed EtOH consumption at 1, but not 25 h after exposure in both HAD and P rats. This result is consistent with the efficacy of N 2 O for acute reduction of EtOH drinking, and supports further research into the use of N 2 O as an adjunct to treatment.
