Calcium Polystyrene Sulphonate BP

Polystyrene sulfonates are polymers derived from polystyrene by the addition of sulfonate functional groups. They are widely used as ion-exchange resins to remove ions such as potassium, calcium, and sodium from solutions in technical or medical applications. Calcium Polystyrene Sulfonate is a cream to light brown, fine powder.


Used in the treatment of hyperkalemia
