1. Neutralizes stomach acid
2. Decreases acid production in the stomach

2. Decreases acid production in the stomach

Explanation: 1. Antacids are medications that neutralize the stomach acid already produced.
2. Histamine blocker medications, such as ranitidine (Zantac), act by reducing acid production by blocking the histamine-2 receptor in the stomach.
3. Sucralfate (Carafate) is given to create a protective barrier on the mucous lining of the esophagus and stomach.
4. Medications that increase peristalsis include metoclopramide (Reglan).
