Potassium cation exchanger

WebPotassium, the second most-abundant cation in the body, performs several important physiological functions, including cellular metabolism, glycogen and protein synthesis, … Potassium binders are medications that bind potassium ions in the gastrointestinal tract, thereby preventing its intestinal absorption. They consist of polystyrene sulfonate resins attached to a cation and are administered either orally or by retention enema to patients who are at risk of developing hyperkalaemia (abnormal high serum potassium levels). Increased serum potassium levels are a condition likely to occur in patients with chronic kidney disease in advanced stages.
