Abstract The ability of RO15‐4513 to block ethanol‐induced motor incapacitation and was assessed via ethanol‐induced suppression of wheel‐running. However, either ethanol or RO15‐4513 administration alone produced an equivalent decrease (75% and 72%, respectively) in wheel‐running performance. Administration of RO15‐4513 at 2.5, 1.25, 0.625, 0.312, 0.156, and 0.078 mg/kg doses produced a dose‐dependent suppression of wheel‐running. Finally, ethanol administration following pretreatment with RO15‐4513 (3.0 mg/kg) produced greater suppression of wheel‐running (89%) than ethanol administration alone (55%). These results demonstrate intrinsic suppressant effects of RO15‐4513, and the lack of generality in the previously reported antagonism of ethanol‐induced intoxication by RO15‐4513.
