Highlights subtype-specific dopaminergic and ACTH regulation in primary aldosteronism; hypothesis-generating and should not yet change practice.
How do metoclopramide, bromocriptine, and ACTH affect plasma aldosterone and renin activities in patients with different subtypes of primary aldosteronism and essential hypertension?
The study demonstrates increased endogenous dopaminergic inhibition of aldosterone secretion in idiopathic hyperaldosteronism compared to dexamethasone-suppressible hyperaldosteronism and essential hypertension.
Veglio et al. (1991) studied this question.
