Chemical compound

Lanthanum carbonate, La2(CO3)3, is the salt formed by lanthanum(III) cations and carbonate anions. It is an ore of lanthanum metal, along with monazite.

Chemistry

Lanthanum carbonate is used as a starting material in lanthanum chemistry, particularly in forming mixed oxides, for example

Human and veterinary medicine

Lanthanum carbonate is used in medicine as a phosphate binder. As a medication it is sold under the trade name Fosrenol by the pharmaceutical company Shire Pharmaceuticals. Fosrenol is the largest of all pills filled in community pharmacies. Sometimes patients forget that fosrenol is not swallowed whole, but instead should be chewed. This has led to severe choking. It is prescribed for the treatment of hyperphosphatemia, primarily in patients with chronic kidney disease. It is taken with meals and binds to dietary phosphate, preventing phosphate from being absorbed by the intestine. For cats suffering from hyperphosphatemia it is available under the trade name Renalzin by Bayer Animal Health.

Other applications

Lanthanum carbonate is also used for the tinting of glass, for water treatment, or as a catalyst for hydrocarbon cracking.
