Abstract

The present invention relates to novel calcium-containing microporous zirconium silicate compositions that are formulated to remove toxins, e.g. potassium ions, from the gastrointestinal tract at an elevated rate without removing calcium from the patient's body. Also disclosed are methods of using calcium-free or low calcium microporous zirconium silicate compositions for the treatment of hyperkalemia in patients also suffering from hypercalcemia.
