Ranitidine lowers gastric acid output in the stomach by reducing histamine’s impact on histamine H2 receptors found on the parietal cells lining the stomach wall. Histamine is the chemical transmitter that causes parietal cells to secrete stomach acid.

Ranitidine reduces stomach acid output and may reduce gastric volume. It has no effect on the pH of any gastric contents that may already be present in the stomach, therefore it must be administered sometime before general anesthesia to be fully effective.
