Enavant PHORALK9 400mg Tablets are a prescription-grade, lower-strength veterinary therapeutic agent designed for both dogs and cats. Containing pure Sevelamer Carbonate (400mg), this advanced medical polymeric phosphate binder is strictly utilized to manage hyperphosphatemia (elevated blood phosphorus levels) secondary to Chronic Kidney Disease (CKD) and staging renal failure. This 400mg strength is specifically engineered to allow for highly precise, incremental dosing in smaller dogs, cats, or pets in earlier stages of renal insufficiency. Unlike traditional calcium or aluminum-based binders, Sevelamer is completely calcium-free, eliminating the dangerous risk of inducing hypercalcemia or mineral tissue calcification while systematically locking onto dietary phosphorus within the intestinal tract so it can be safely excreted.
