| Common Name | Roxatidine acetate |

| Description | Roxatidine acetate is only found in individuals that have used or taken this drug. It is a specific and competitive H2 receptor antagonist. It is currently approved in South Africa under the tradename Roxit.The H2 antagonists are competitive inhibitors of histamine at the parietal cell H2 receptor. They suppress the normal secretion of acid by parietal cells and the meal-stimulated secretion of acid. They accomplish this by two mechanisms: histamine released by ECL cells in the stomach is blocked from binding on parietal cell H2 receptors which stimulate acid secretion, and other substances that promote acid secretion (such as gastrin and acetylcholine) have a reduced effect on parietal cells when the H2 receptors are blocked. |
