Ball-and-stick model of cimetidine, the prototypical H 2 -receptor antagonist. The H2 receptor antagonists are a class of drugs used to block the action of histamine on parietal cells (specifically the histamine H2 receptors) in the stomach, decreasing the production of acid by these cells.he H 2 antagonists are competitive antagonists of histamine at the parietal cell H 2 receptor. They suppress the normal secretion of acid by parietal cells and the meal-stimulated secretion of acid.
They prevent new stomach acid from forming, so the stomach and esophagus can heal and you can be free of acid reflux symptoms. Zantac, Tagamet, and Pepcid are few examples of H2 receptor antagonists. Famotidine (Pepcid) is available in 20mg and 40mg. You can take 20mg twice daily for six weeks.
