heartburn medicine
Acid Reducers for Heartburn. There are two types of drugs that work to reduce the production of acid in the stomach: histamine antagonists (H2 antagonists or H2 blockers) and proton pump inhibitors (PPIs).
Antacids neutralize stomach acid to help relieve heartburn, sour stomach, acid indigestion, and stomach upset. Some antacids also contain simethicone, an ingredient that helps eliminate excess gas. Some antacids contain ingredients that can cause diarrhea, such as magnesium, or constipation, such as aluminum.
