Description : FOSROS-400 Tablets contain Sevelamer Carbonate 400 mg, a phosphate-binding agent used to control hyperphosphatemia in patients with chronic kidney disease (CKD) on hemodialysis or peritoneal dialysis. It works by binding dietary phosphate in the gut and preventing its absorption into the bloodstream. FOSROS-400 is calcium- and metal-free, making it safe for long-term use without increasing the risk of vascular calcification. It helps maintain healthy phosphate levels, supports bone health, and reduces complications associated with CKD under nephrology care.
