Final answer:
Calcium acetate is used as a phosphate binder to treat high blood phosphate levels in patients with kidney disease on dialysis.
Step-by-step explanation:
The drug calcium acetate is primarily used as a phosphate binder to treat hyperphosphatemia (high blood phosphate levels) in patients with kidney disease on dialysis. It works by binding to the phosphate in the food you eat, so that it can be eliminated from the body without being absorbed. This helps prevent dangerously high levels of phosphate in the blood, which can cause bone and heart problems among other issues.
