  • Title: Ro 19-4603, a benzodiazepine receptor inverse agonist, attenuates voluntary ethanol consumption in rats selectively bred for high ethanol preference.

    Journal: Alcohol Alcohol; 1990; 25(5):449-52. PubMed ID: 1965120.
    Abstract:
    The effect of Ro 19-4603, a novel potent partial inverse agonist of benzodiazepine (BZ) receptors, on voluntary ethanol intake was examined in a rat line selectively bred for ethanol preference (Sardinian ethanol preferring, sP, rats). Ro 19-4603, 1 mg/kg i.p., three times daily, reduced voluntary ethanol consumption by about 40% during 7 days of treatment, but failed to reduce water intake. The results suggest that the GABA/BZ receptor complex may play a role in the reinforcing property of ethanol.
