The inhibition of spontaneous locomotor behavior of mice by norcocaine was antagonized neither by the adrenoceptor antagonists yohimbine and phentolamine, nor by the neuroleptics haloperidol and spiperone, at low doses aimed at presynaptic dopamine receptors. In contrast, the antagonists were effective in reducing the hypomotility induced by clonidine and apomorphine, respectively. These results make it unlikely that central alpha 2-adrenergic or presynaptic dopamine receptors are involved in the hypomotive effect of norcocaine.
