NCIt definition : The potassium salt form of prorenoate, a steroidal aldosterone antagonist with potassium-sparing
diuretic activity. Prorenoate antagonizes the activity of aldosterone at the mineralocorticoid
receptor in the nephron and thereby prevents sodium reabsorption. This interferes
with the sodium/potassium exchanger and causes sodium and water excretion while reducing
potassium excretion.;
