The effects of clozapine and haloperidol on initiation of alcohol drinking in P rats in Experiment 1. (A) Alcohol Intake in g/kg: The 12 mg/kg CLOZ group, but not the HAL groups, drank less alcohol than the VEH group. There was an increase in alcohol intake in the 12 mg/kg CLOZ group over the 20-day Alcohol Access Period. However, alcohol intake appears to remain lower than levels seen in the VEH-treated animals. (B) Alcohol preference: Only the 12 mg/kg CLOZ group had significantly lower alcohol preference than the VEH group over the 20-day Alcohol Access Period. Alcohol preference in the 12 mg/kg CLOZ group was also lower than that in all HAL groups. There was a gradual increase over time in alcohol preference in the 12 mg/kg CLOZ group. However, alcohol preference in this group appears to be lower than the VEH group during the latter part of the Alcohol Access Period. Alcohol preference in the VEH group and in the haloperidol-treated groups remained steadily high.
