PGE2: opposite effect on catecholamine release from phaeochromocytoma and adrenal medulla
Abstract:
The effect of PGE2 on catecholamine release from human adrenal medulla and phaechromocytoma was studied in slices incubated in vitro. In each of 3 normal human adrenal medullae PGE2 (10(-7) M) caused a significant inhibition of the release of catecholamines in in vitro incubation. In each of 3 phaechromocytomas studied PGE2 (10(-7) M) caused a significant increase of catecholamine release in in-vitro incubation. The possible relevance of this mechanism to the regulation of catecholamine release in phaeochromocytoma is discussed.

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...
Adrenergic Agonists: Mixed-Action Agents
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
