How Spironolactone works
Spironolactone is a potassium-sparing diuretic.
It operates by inhibiting the effects of the hormone aldosterone, which typically regulates water and salt balance in our bodies. Normally, aldosterone acts on the kidneys to promote the absorption of sodium and water while enhancing the excretion of potassium.
