How it works
AldactoneDigoxin
Aldactone (Spironolactone) is a potassium-sparing diuretic that blocks aldosterone (a hormone) and helps the kidney get rid of excess fluids in your body.Digoxin helps your heart work more efficiently. It makes your heart pump slower and stronger, which helps it get more blood and oxygen out to your body and organs.
