The role of potassium binders
First, potassium binders taken orally absorb potassium derived from food intake, making it unavailable for absorption from the gastro-intestinal tract. It is then excreted tightly bound to a resin.
Second, they bind potassium in the colon derived from intestinal secretion. In renal failure patients, the colon enforces its secretion of potassium into the lumen to counterbalance to a certain degree the loss of kidney function. Thus, oral medications may support the management of hyperkalaemia to a certain extent.
Fresenius Medical Care supports this programme of treatment through its potassium binder.
