What type of medication is Renagel?

Renagel is classified as a phosphate binder, which means its primary function is to bind phosphorus in the digestive tract, thus preventing its absorption into the bloodstream. This is particularly important for patients with chronic kidney disease (CKD), as their kidneys cannot effectively excrete phosphorus, leading to high blood phosphorus levels and associated complications such as bone disease and cardiovascular problems. By managing phosphorus levels, Renagel helps maintain better mineral balance and overall health in these patients.

In contrast, the other types of medications listed have different purposes. Antibiotics are used to fight infections, antihistamines are commonly employed to relieve allergy symptoms, and antipyretics are used to reduce fever. None of these categories are relevant to the function of Renagel, which focuses solely on managing phosphorus levels in the body.
