Dyrenium (Triamterene)

General Information

Dyrenium (Triamterene) is used to decrease swelling or also called edema caused by:

  • Congestive heart failure
  • Cancer
  • Liver disease
  • Kidney disease

This helps your body get rid of extra water. This can help your kidneys work better. This can also lessen symptoms such as trouble breathing and swelling in your feet, hands, ankles, or belly.


How does Dyrenium (Triamterene) work?

Dyrenium (Triamterene) works by blocking sodium and water reabsorption in the kidneys. It also reduces water and sodium in the body. To compensate for the increased amount of water and sodium in the tubules that will be lost as urine. The kidney also tries to reabsorb more water and sodium. It is by removing potassium from the blood and putting it into the tubules in exchange for sodium and water in the tubules.

As a result, blood potassium levels fall. This drug is a diuretic that prevents reabsorption of sodium in exchange for potassium. Thus, it reduces sodium and water in the body but also prevents the depletion of potassium. For this reason, this is called a potassium-sparing diuretic. By combining hydrochlorothiazide with triamterene, water and sodium are eliminated from the body without the loss of potassium. However, this drug may allow potassium levels to increase so potassium levels should be closely monitored.
