Which of the following is an aluminum hydroxide product that serves as a phosphate binder?

Aluminum hydroxide is primarily used in the medical field as a phosphate binder, particularly in patients with chronic kidney disease who are at risk of hyperphosphatemia. The correct choice, AlternaGel, contains aluminum hydroxide and is specifically formulated to bind phosphate in the gastrointestinal tract, reducing its absorption into the bloodstream. By doing so, it helps lower serum phosphate levels, which is crucial for maintaining proper bone health and preventing related complications in patients with renal impairment.

In contrast, Fosrenal is primarily a lanthanum carbonate product used for similar purposes but does not contain aluminum hydroxide. Mannitol is an osmotic diuretic used to reduce intracranial pressure and treat renal failure but is not involved in phosphate binding. Cisplatin is a chemotherapy medication used to treat various cancers and has no relation to phosphate binding in the body.
