What is the category of the medication Velphoro, which a dialysis patient might be taking?

Velphoro is classified as a phosphate binder, specifically used to manage hyperphosphatemia in patients with chronic kidney disease, particularly those undergoing dialysis. This medication works by binding to dietary phosphate in the gastrointestinal tract, preventing its absorption into the bloodstream. For dialysis patients, controlling phosphate levels is crucial since their kidneys are less able to excrete phosphate, leading to elevated levels that can cause complications such as bone disease and cardiovascular issues.

In this scenario, the other categories listed do not apply to Velphoro. Cation exchange resins are typically used for conditions like hyperkalemia or to lower cholesterol levels, angiotensin receptor blockers primarily treat hypertension and heart failure, and calcium channel blockers are used for a variety of cardiovascular conditions. Therefore, identifying Velphoro as a phosphate binder is critical for managing the specific needs of dialysis patients.
