Mechanism of action

Cimetidine competitively inhibits histamine H2 receptors on gastric parietal cells, thereby decreasing both basal and stimulated gastric acid production. This reduction in gastric acidity is used to treat and prevent peptic ulcer disease, gastroesophageal reflux disease (GERD), and other acid-related conditions. The IV formulation allows for rapid onset of action in acute clinical settings.
