Potassium-sparing diuretics are drugs to remove excess fluid in the body through urine while maintaining potassium levels in the blood . This drug is commonly used to lower high blood pressure.
Potassium-sparing diuretics work by inhibiting the action of the hormone aldosterone and inhibiting the exchange of sodium and potassium in the kidneys. This way of working causes more sodium to be excreted through the urine while maintaining potassium levels in the blood.
High sodium levels in the urine will attract water from the body so that the amount of water excreted will also increase. Removal of water and sodium from the body will cause a decrease in blood pressure in hypertensive patients .
Apart from treating hypertension, potassium-sparing diuretics can also be used to prevent, treat, or relieve symptoms of several conditions and diseases below:
Ascites due to cirrhosis
Aldosteronism (too much aldosterone) due to disturbances in the adrenal glands
Polycystic ovarian syndrome ( PCOS )
Potassium-sparing diuretics are usually used with other types of diuretic drugs to increase their effectiveness, as well as to keep potassium levels in the blood normal. This is because other types of diuretics generally cause a decrease in potassium levels in the blood, and can even cause hypokalemia .
