Abstract |
Alcohol preference and manifestation of alcoholism are thought by many to be associated with serotonin (5-HT) dysfunction in the brain. Thus, experiments were performed to determine the effect of acute and sub-chronic administration (s.c.) of + or - 3,4-methylenedioxymethamphetamine (MDMA), an amphetamine analog which stimulates 5-HT release, on alcohol preference in two strains of alcohol preferring rats, the Fawn-Hooded (FH) and alcohol preferring (P) rats. Our results show that a single administration of 5.0 mg/kg MDMA significantly decreased ethanol intake in both FH and P rats and increased water intake. Sub-chronic administration of 5.0 mg/kg MDMA for three consecutive days significantly attenuated alcohol intake in both strains. |
