These are (mainly consisting of hydrochloric acid) responsible for the production of stomach acid. In these cells by blocking an enzyme which is called proton pump. It “pumps” protons as part of the hydrochloric acid in the stomach area. Ultimately Omeprazole inhibits acid production thus irreversibly, making the environment in the stomach is less acidic. The extent of gastric acid output inhibition is dose-dependent.
