MOA |
Competitively inhibit the binding of histamine to receptors on gastric parietal cells (H2 receptors) to reduce gastric acid secretion
|
|
OTC H2RA's
drug interactions |
ketoconazole, itraconazole, iron, calcium carbonate
Cimetidine has the most interactions (P450 3A4, 2D6, 1A2, and 2C9 inhibitor) Cimetidine inhibits metabolism of warfarin, phenytoin, theophylline |

Could mask symptoms of stomach cancer. |
true
