Phoslink 667 contains Calcium Acetate (667 mg) and is primarily used as a phosphate binder for patients with end-stage renal disease or Chronic Kidney Disease (CKD). In individuals with impaired kidney function, phosphorus levels in the blood can become dangerously high. This medication works by binding to phosphorus found in the food you eat, preventing it from being absorbed into the bloodstream. The bound phosphorus is then eliminated through the digestive tract. By controlling phosphate levels, it helps prevent bone issues and cardiovascular complications. It must be taken with meals and strictly according to a doctor's prescription.
