Used primarily in the treatment of chronic kidney disease (CKD) to manage high phosphate levels in the blood, known as hyperphosphatemia. It works as a phosphate binder, taken orally with meals to prevent the absorption of dietary phosphate in the digestive tract. By reducing phosphate levels, it helps prevent complications such as bone disorders and cardiovascular issues commonly associated with CKD. It is particularly beneficial for patients on dialysis, as their kidneys are unable to effectively remove excess phosphate. The medication is non-calcium-based, making it a suitable option for patients who need to avoid calcium-containing phosphate binders.
