Dr. Moalemi explains potassium sparing diuretics. Potassium-sparing diuretics are medicines that increase diuresis (urination) without the loss of potassium. They are generally weak diuretics and work by interfering with the sodium-potassium exchange in the distal convoluted tubule of the kidneys or as an antagonist at the aldosterone receptor. Further details will be explained in the video by our highly experienced certified cardiologist Dr. Moalemi.
