How Does Prilosec OTC Work?

Prilosec OTC is part of a group of medications called proton pump inhibitors (PPIs). The stomach contains tiny pumps (called proton pumps) that produce acid. Prilosec OTC works by binding to these proton pumps, stopping the production of acid. Prilosec is very effective at decreasing acid production.
