Urinary Sodium and Potassium, and Aldosterone Secretion before and after Guanethidine Treatment, and Six Months after Surgical Removal of the Tumor (the Stippled Areas Represent the Normal Ranges).

Primary aldosteronism treatment response was associated with higher plasma renin activity and serum potassium levels and lower aldosterone.

Aldosterone antagonists (spironolactone, eplerenone) also known as “potassium sparing diuretics” block the action of aldosterone inhibiting the reuptake of sodium and water. Normally ...

Through this mechanism, diuretics may increase ... and impairing arterial compliance. Aldosterone also promotes potassium and magnesium depletion, which is potentially proarrhythmic.

Aldosterone is a steroid hormone that plays a critical role in the homeostasis of sodium, potassium and volume. Aldosterone is secreted primarily by cells of the zona glomerulosa in the adrenal ...

Elevated aldosterone stimulates sodium reabsorption in the cortical collecting duct as a backup mechanism of maintaining homeostasis. This mechanism results in increased potassium and hydrogen ion ...
