Alginic Acid Sodium Bicarbonate
Alginic Acid/Sodium Bicarbonate is a combination medication used to treat symptoms of acid reflux, heartburn, and gastroesophageal reflux disease (GERD). It works by neutralizing stomach acid and creating a protective foam barrier that prevents stomach contents from flowing back into the esophagus. This medication is typically taken after meals and at bedtime for symptom relief.
