Abstract
The present invention is a method of producing a lanthanum carbonate hydroxide or lanthanum oxycarbonate which has improved properties. The method involves the use of a water soluble lanthanum and a water soluble non-alkali metal carbonate or bicarbonate. The resulting material can be used as a phosphate binder individually or for treating patients with hyperphosphatemia.
Claims
exact text as granted — not AI-modified1 . A lanthanum dioxycarbonate compound which comprises one or more polymorphs of formulae La 2 O 2 CO 3 and La 2 CO 5 , and wherein said lanthanum dioxycarbonate compound includes about 0.75% by weight or less of sodium, and has particles having spherical morphology.
