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.
Cimetidine is indicated to reduce gastric acid secretion and to treat the following disease states: duodenal ulcers, non-malignant gastric ulcers, gastroesophageal reflux disease, and pathological hypersecretion associated with Zollinger-Ellison Syndrome, systemic mastocytosis, and multiple endocrine adenomas. It is indicated for prophylaxis of recurrent gastric or duodenal ulcers, as adjunctive therapy in the management of cystic fibrosis in children, and to treat NSAID induced lesions and gastrointestinal symptoms.
