It is important to note that many of the over-the-counter medicines described here contain sodium, a component of salt. If you are on a salt-restricted diet, you will need to read labels carefully to make sure you do not ingest too much sodium.

Antacids are useful in treating acid reflux because they are weak bases and therefore convert the caustic and potentially dangerous hydrochloric acid found in stomach acid into neutral water and a salt. Antacids also decrease the potential caustic effect of pepsin, another chemical found in gastric secretions.
