Answer

Histamine H2 Antagonists

These agents are used prophylactically to prevent complications.

Cimetidine (Tagamet)

Cimetidine inhibits histamine at H2 receptors of gastric parietal cells, which results in reduced gastric acid secretion, gastric volume, and hydrogen concentrations.

Ranitidine (Zantac)

Ranitidine inhibits histamine stimulation of the H2 receptor in gastric parietal cells, which, in turn, reduces gastric acid secretion, gastric volume, and hydrogen ion concentrations.

Famotidine (Pepcid)

Famotidine competitively inhibits histamine at the H2 receptor of gastric parietal cells, resulting in reduced gastric acid secretion, gastric volume, and hydrogen ion concentrations.

Nizatidine (Axid)

Nizatidine competitively inhibits histamine at the H2 receptor of the gastric parietal cells, resulting in reduced gastric acid secretion, gastric volume, and reduced hydrogen concentrations.
