Inhibition of dopamine-β-hydroxylase suppresses cocaine self-administration reinstatement in rats. Pre-treatment with the selective inhibitor nepicastat decreased noradrenaline outflow induced by cocaine and amphetamine in the medial prefrontal cortex and in the nucleus accumbens, and dramatically potentiated dopamine outflow in the medial prefrontal cortex, but not in the nucleus accumbens. The effect on cortical dopamine level was mimicked by α2adrenergic antagonist administration and reverted by α2adrenergic agonist. The data suggest that noradrenaline tonically inhibit dopamine release in the medial prefrontal cortex.
