API Description: Calcium polystyrene sulfonate is a cation-exchange resin used to treat hyperkalemia (high blood potassium levels). It works by exchanging calcium ions for potassium ions in the gut, facilitating the removal of excess potassium through the feces. Typically administered orally or rectally, it is used in both acute and chronic settings for potassium management.
