  • Publication number: 20140377560
    Abstract: The present invention relates to novel microporous zirconium silicate compositions that are formulated to remove toxins, e.g. potassium ions, from the gastrointestinal tract at an elevated rate without causing undesirable side effects. The preferred formulations are designed avoid increase in pH of urine in patients and/or avoid potential entry of particles into the bloodstream of the patient. Also disclosed is a method for preparing high purity crystals of UZSi-9 exhibiting an enhanced level of potassium exchange capacity. These compositions are particularly useful in the therapeutic treatment of hyperkalemia.

  • Publication number: 20140302175
    Abstract: The present invention relates to novel methods of using microporous zirconium silicate to reduce the risk of hyperkalemia and to lower aldosterone levels in the treatment of chronic kidney disease and/or chronic heart disease with therapies comprising diuretics. The invention provides a safe way to reduce the risk of hyperkalemia and to lower aldosterone. The invention also relates to treatment of other conditions that can occur either alone or in connection with hyperkalemia, chronic kidney disease, and/or chronic heart disease.
