Magaldrate is used to treat and relieve symptoms associated with hyperacidity conditions, including heartburn, acid indigestion, sour stomach, peptic ulcer disease, and gastroesophageal reflux disease (GERD). It is also used to manage gastritis and discomfort caused by overeating or consuming irritating foods.
Magaldrate is a combination antacid containing aluminum hydroxide and magnesium hydroxide. It works by chemically neutralizing gastric acid in the stomach, which raises the pH and reduces the acidity of stomach contents. This helps relieve the burning sensation and discomfort associated with excess stomach acid.
Magaldrate should be taken as directed by a healthcare provider or according to package instructions. It may interact with other medications, so it should be taken at a different time than other drugs. Long-term use should be monitored by a physician due to potential effects on electrolyte levels. Patients with kidney disease should use this medication with caution and only under medical supervision.
