How It Works. Antacids make stomach juices less acidic (neutralize stomach acid). Antacids with alginic acid (such as Gaviscon) contain a foaming agent that floats on top of the stomach contents. This may help keep stomach juices from coming in contact with your esophagus. Antacids that contain simethicone (such as Maalox Anti-Gas or Mylanta Gas) may break down gas bubbles in your stomach. This may help reduce burping that might push stomach acid into your esophagus.
