Spironolactone is a potassium-sparing diuretic (water pill) that prevents your body from absorbing too much salt and keeps your potassium levels from getting too low.
Aldactone is a potassium-sparing diuretic. It works by blocking the hormone aldosterone, causing the kidney to eliminate excess water, save potassium, and lower blood pressure.
