Renagel tablets contain the active ingredient Sevelamer hydrochloride and are specifically formulated to manage and control serum phosphorus levels in patients with chronic kidney disease. By binding to phosphate in the digestive tract, these tablets effectively reduce the amount of phosphate absorbed into the bloodstream, helping to lower its levels. Renagel is crucial for patients undergoing dialysis, as it prevents complications related to high phosphate levels, such as bone disorders. This medication plays a vital role in maintaining proper phosphorus balance, thereby supporting both renal and overall systemic health.
