the inability of flumazepil ( 10-20 mg/kg ; ro 15-1788 , a benzodiazepine receptor antagonist ) to reverse the effects of yohimbine suggested that the low-affinity effect of yohimbine to displace the binding of benzodiazepines from their receptors , is not important in its behavioural effects in the holeboard , but that these effects are attributable to the alpha 2-antagonist action of yohimbine .
