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.
