How Do Potassium Binders Work?

Potassium binders are drugs used for treating hyperkalemia or high potassium levels in the blood. They bind to the excess potassium in the bowels, which is then excreted from the body through the stool.

Potassium binders may capture potassium in exchange for calcium or sodium ions found in the colon. The binding of potassium reduces the free potassium in the bowel, thereby lowering blood potassium levels.
