Sevcar 400mg tablet contains an active ingredient called Sevelamer. It belongs to the medication class known as phosphate binders. It is used to manage hyperphosphatemia (high blood phosphate levels) in adult patients undergoing dialysis (hemodialysis or peritoneal dialysis) and patients with chronic kidney disease who have elevated serum phosphorus levels. It should be used with other treatments, such as calcium supplements and vitamin D, to prevent bone disease. High blood phosphorus levels can cause calcification, where hard deposits form and stiffen blood vessels, affecting blood flow.
