About H2 blockers. H2 blockers â also known as histamine 2 receptor antagonists â are medications that decrease the amount of acid the stomach produces. These drugs are used to treat various gastrointestinal disorders.2 blockers work by preventing the action of histamine, a substance released by the human immune system during allergic reactions. Histamine normally interacts with gastric H2 receptors to produce stomach acid. The H2 blockers inhibit this response and help reduce gastric acid output.
