A proton pump inhibitor (PPI) is a drug used to reduce the production of stomach acid giving the esophagus, stomach, and duodenum (first part of the intestines) time to heal from irritation and erosive damage. The decrease in acid production will also help reduce acid reflux related heartburn.
Those who are pregnant have fewer remedies for heartburn relief. Many foods, herbs, and OTC medications are considered harmful during pregnancy.
There are 3 levels of OTC medications for treating heartburn and acid reflux: antacids, histamine receptor blockers (H2 blockers), and Proton Pump Inhibitors (PPI’s).
