Hydrocortisone-mediated increase of norepinephrine uptake by brain slices
Abstract:
Slices of cerebral cortex from the adult rat were incubated with and without hydrocortisone succinate, and their subsequent uptake of isotopically labeled norepinephrine was measured. Preincubation with hydrocortisone resulted in a statistically significant increase in the amount of exogenous norepinephrine taken up by the slices. Preincubation with corresponding concentrations of sodium succinate was without effect. The principal effect of the hydrocortisone-mediated increase in norepinephrine concentration is apparently on an active transport mechanism.

Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...
