It is also used for the treatment of bone disease.

Zynagel 400mg Tablet contains sevelamer that works by binding phosphate in the gastrointestinal tract and decreasing absorption. It effectively reduces excess phosphate levels in the blood, prevents the unsafe build-up of phosphate in your body, helps keep your bones strong, and decreases the risk of heart disease and strokes.

Zynagel 400mg Tablet belongs to a group of medications called phosphate binder, which works by binding phosphate in the gastrointestinal tract and decreasing its absorption. This lowers the phosphate concentration in the body. It effectively reduces excess phosphate levels in the blood, prevents the unsafe buildup of phosphate in your body, helps keep your bones strong, and decreases the risk of heart disease and strokes. Zynagel 400mg Tablet controls hyperphosphataemia (high blood phosphate levels) in adult patients on dialysis (a blood clearance technique), patients undergoing hemodialysis (using a blood filtration machine) or peritoneal dialysis (where the fluid is pumped into the abdomen and an internal body membrane filters the blood), and patients with chronic kidney disease.

Hyperphosphatemia: Hyperphosphatemia is defined as an increased phosphate level in the blood. This condition is often a complication of chronic kidney disease. Phosphate is an important electrolyte. It strengthens your bones and teeth and produces energy.  When phosphate levels increase in the blood due to kidney impairment (the kidney does not remove extra phosphate out of the body), this can cause muscle problems and increase the risk of weak bones, heart attacks, and strokes. It is more common in people with chronic kidney disease and people on dialysis. Symptoms may include itchy skin, red eyes, bone pain, and fractures.
