| Source Type: | approved; investigational |
| Compound Type: | small molecule |
| Compound Name: | Cimetidine |
| Synonyms: | |
| Molecular Formula: | C10H16N6S |
| SMILES: | CN\C(NCCSCC1=C(C)NC=N1)=N\C#N |
| Structure: |
|
| DrugBank Description: | A histamine congener, it competitively inhibits histamine binding to histamine H2 receptors. Cimetidine has a range of pharmacological actions. It inhibits gastric acid secretion, as well as pepsin and gastrins output. It also blocks the activity of cytochrome P-450 which might explain proposals for use in neoadjuvant therapy. |
| CAS Number: | 51481-61-9 |
| Molecular Weight: | 252.339 |
| DrugBank Indication: | For the treatment and the management of acid-reflux disorders (GERD), peptic ulcer disease, heartburn, and acid indigestion. |
| DrugBank Pharmacology: | Cimetidine is a histamine H<sub>2</sub>-receptor antagonist. It reduces basal and nocturnal gastric acid secretion and a reduction in gastric volume, acidity, and amount of gastric acid released in response to stimuli including food, caffeine, insulin, betazole, or pentagastrin. It is used to treat gastrointestinal disorders such as gastric or duodenal ulcer, gastroesophageal reflux disease, and pathological hypersecretory conditions. Cimetidine inhibits many of the isoenzymes of the hepatic CYP450 enzyme system. Other actions of Cimetidine include an increase in gastric bacterial flora such as nitrate-reducing organisms. |
| DrugBank MoA: | Cimetidine binds to an H<sub>2</sub>-receptor located on the basolateral membrane of the gastric parietal cell, blocking histamine effects. This competitive inhibition results in reduced gastric acid secretion and a reduction in gastric volume and acidity. |
