Phosphate Binders: Your Questions Answered
This can be challenging but is very
important. Many of the common foods we eat are high in phosphate and it is very difficult to avoid
some of these foods. Since these foods cannot easily be avoided, portion control is important.
Speaking to a renal dietitian and learning how to read nutrition labels can help you control your
phosphate levels.
Drugs (Phosphate binders):
There are various phosphate binders available in the United States: calcium carbonate (OScal®),
calcium acetate (PhosLo®), sevelamer (Renvela®), lanthanum (Fosrenol®) and aluminum hydroxide
(Amphojel®). They work by binding to phosphate in the gastrointestinal tract and forming a compound
that cannot be absorbed into the blood and instead is then excreted in the feces. These medicines are
most often used in patients who have end-stage renal disease (ESRD) or are on dialysis. However,
they are sometimes used in patients with stages 3 and 4 chronic kidney disease (CKD).
