Lanthanum carbonate,La2(CO3)3, is thesalt formed bylanthanum(III)cations andcarbonateanions. It is an ore oflanthanum metal (bastnäsite), along withmonazite.
Lanthanum carbonate is used as a starting material in lanthanum chemistry, particularly in forming mixed oxides, for example
Lanthanum carbonate is used inmedicine as aphosphate binder.[1] As a medication it is sold under the trade nameFosrenol by the pharmaceutical companyShire Pharmaceuticals. Due to its large size (1000 mg tablet is 2.2 cm in diameter), it may be possible to choke on the tablet if it is not chewed. It isprescribed for the treatment ofhyperphosphatemia, primarily in patients withchronic kidney disease. It is taken with meals and binds to dietaryphosphate, preventing phosphate from being absorbed by theintestine. For cats withhyperphosphatemia it is available under the trade nameRenalzin byBayer Animal Health.[2]
However, when lanthanum carbonate is used for treating hyperphosphatemia, its side effects, namelymyalgia, muscular cramping, andperipheral edema, should be clinically monitored.[3]
Lanthanum carbonate is also used for the tinting of glass,[citation needed] for water treatment, and as acatalyst forhydrocarbon cracking.
