Fosrenol (Lanthanum Carbonate)

General Information

Fosrenol (Lanthanum Carbonate) is used to lower high blood phosphate levels. It is in people who are on dialysis due to severe kidney disease. Dialysis removes some phosphate from your blood. It is difficult to remove enough to keep your phosphate levels balanced.

Decreasing blood phosphate levels may help keep your bones strong. It may also decrease the risk of heart disease and strokes. Those may result in a high level of phosphate.

How does Fosrenol (Lanthanum Carbonate) work?

Fosrenol (Lanthanum Carbonate) lessens the absorption of phosphate which is a phosphate binder. It is by forming insoluble lanthanum phosphate complexes that pass through the gastrointestinal (GI) tract unabsorbed. Both serum phosphate and calcium phosphate product are decreased. It is the consequence of reduced dietary phosphate absorption.
