Treatment of heartburn, acid indigestion, gastroesophageal reflux disease (GERD), peptic ulcers, and hyperphosphatemia (elevated phosphate levels) in chronic kidney disease patients on dialysis
Acts as a buffering agent by neutralizing hydrochloric acid in the stomach, which raises gastric pH and reduces acidity. As a phosphate binder, it binds to dietary phosphate in the gastrointestinal tract to decrease phosphate absorption.
May cause constipation and should not be taken at the same time as other medications as it can interfere with absorption. Long-term use may lead to aluminum toxicity, particularly in patients with renal impairment. Use with caution in patients on low-phosphate diets.
