Tums, Amphojel, Alucaps, Renagel, Renvela, and Phoslo are examples of what?

• A. Antacids
• B. Dialyzers
• C. Phosphate binders
• D. Iron supplements

Answer: (C)

These drugs are all phosphate binders, used to control high phosphate levels in people with kidney failure. In chronic kidney disease, the kidneys can’t remove phosphate effectively, so dietary phosphate builds up and can cause bone and vascular problems. Taking a phosphate binder with meals binds the phosphate in the gut so it can’t be absorbed and is excreted in the stool. That’s why Tums (calcium carbonate), Amphojel (aluminum hydroxide), Alucaps, Renagel (sevelamer), Renvela (sevelamer carbonate), and Phoslo (calcium acetate) are grouped together here—they all serve this function. The binder’s type matters for specifics: calcium-based binders add calcium and help lower phosphate, aluminum-based binders carry more long‑term toxicity risk, and sevelamer binds phosphate without adding calcium or aluminum. Monitor phosphate and calcium levels and be aware of potential GI side effects or other risks tied to the binder type.
