Adverse Drug Reaction Classification System

Pharmaceutical Information
Drug Name Cimetidine hydrochloride
Drug ID BADD_D00468
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.
Indications and Usage 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.[L30280] 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.[L30280]
