Antacids are over-the-counter medications that help neutralize stomach acid. They work differently from other acid reducers such as H2-receptor blockers or proton pump inhibitors, which work by reducing or preventing the secretion of stomach acid. Antacids usually come as a liquid, chewable gummy or tablet, or tablet that you dissolve in water to drink. Antacids are distinct from acid-reducing drugs like H2-receptor antagonists or proton pump inhibitors and they do not kill the bacteria Helicobacter pylori, which causes most ulcers.
