DRUG CLASS AND MECHANISM: Sodium bicarbonate is an alkalinizing agent (antacid) that reduces stomach acid. It is a commonly used antacid to treat heartburn, acid ingestion and upset stomach.

Oral administration of sodium bicarbonate results in the neutralization of hydrochloric acid in the stomach (raises blood and urinary pH) and the formation of sodium chloride, carbon dioxide, and water.
