Has iprindole an alpha adrenergic activity?

1. Acute administration of iprindole potentiated the toxicity of 1-norepinephrine and increased the intensity of oxotremorine-induced tremors. 2. On the forced swimming test combination iprindole with imipramine reduced the duration of immobility. 3. The action of yohimbine on the locomotor activity was antagonized by a pre-injection of iprindole. 4. Iprindole increased and prolonged exophthalmia and loss of righting reflex induced by xylazine. 5 All these results seems indicate that iprindole has an indirect alpha 1 and alpha 2 adrenergic activity.
