Why is Kayexalate given for hyperkalemia?
Considering this, what does Kayexalate do to potassium?
Kayexalate binds itself to potassium in your digestive tract. This helps prevent your body from absorbing too much potassium. Kayexalate is used to treat high levels of potassium in the blood, also called hyperkalemia.
In this way, why is Kayexalate used in renal patients?
Sodium polystyrene sulfonate (SPS) (Kayexalate®) is a cation exchange resin that trades sodium ions for potassium ions, mostly in the large intestine, to enhance the fecal elimination of excess potassium. As patients progress to higher stages of CKD, the only definitive therapy for hyperkalemia is dialysis.
Other treatment options for hyperkalemia include IV calcium, insulin, sodium bicarbonate, albuterol, and diuretics. A new drug (patiromer) was recently approved for the treatment of hyperkalemia, and additional agents are also in development.
