Used as an antacid to neutralize stomach acid for relief of heartburn, indigestion, and upset stomach. It is also employed in the treatment of conditions involving excess stomach acid, such as gastritis, peptic ulcers, and gastroesophageal reflux disease (GERD). Additionally, aluminum hydroxide helps reduce phosphate levels in patients with chronic kidney disease by binding phosphate in the digestive tract, preventing its absorption. Commonly found in over-the-counter and prescription medications, it works slowly and provides prolonged symptom relief.
