The chemical structure has some elements of similarity with cimetidine, but does not have a blocking effect on H2 receptors. However, it is a very effective anti-ulcer agent. The drug is very lipophilic, easily penetrates into the parietal cells of the gastric mucosa, concentrates in them and has a cytoprotective effect; protects the mucous membrane of the stomach and duodenum. It is believed that the antiulcer effect of omeprazole is mainly associated with the blockage of the "acid pump", with a decrease in the secretion of stomach acid, which is associated with inhibition of Na + -K + -ATPase in the membranes of parietal cells.
Omeprazole is used for severely flowing peptic ulcers that cannot be treated with other anti-ulcer drugs, for erosive reflux esophagitis, and for Zollinger-Ellison syndrome.
