Spironolactone is a potassium-sparing diuretic used to treat edema associated with heart failure, liver cirrhosis, and nephrotic syndrome. It works by inhibiting aldosterone, promoting sodium and water excretion while retaining potassium. Its clinical significance lies in managing fluid overload and hypertension. In summary, Spironolactone is vital for treating conditions involving fluid retention.
Spironolactone antagonizes aldosterone receptors, leading to increased sodium and water excretion while conserving potassium.
