contain aluminum should be avoided, to prevent aluminum poisoning.
Non-calcium phosphate binders. These are
calcium- and aluminum-free. Examples are sevelamer and lanthanum. They are also used to
control serum phosphate and reduce PTH levels.
Calcitriol. This is a vitamin D
derivative. It may be used to increase calcium levels and help store excess
phosphate in bone. While taking calcitriol, you will be watched closely for hypercalcemia.
