Products Description
Cimetidine acts as an H2‑receptor antagonist. It powerfully suppresses gastric acid secretion stimulated by food, histamine and pentagastrin, and reduces gastric acidity. The compound delivers preventive and protective effects against chemically‑induced corrosive gastritis, and exhibits favorable efficacy for stress‑related gastric ulcers as well as upper gastrointestinal hemorrhage. Possessing anti‑androgenic properties, it shows partial therapeutic value in managing hirsutism. Furthermore, it attenuates the activity of immunosuppressive cells to elevate immune responses, which may inhibit tumor progression and prolong survival. Clinically, it is applied for the treatment of duodenal ulcers, gastric ulcers, upper gastrointestinal bleeding and other relevant disorders.

Products Application
Cimetidine, first launched commercially in 1975, represents the original selective H2‑receptor antagonist developed for the treatment of peptic ulcer disease. Its core function lies in suppressing gastric acid secretion and lowering gastric acidity, which confers protective and preventive benefits against chemically provoked corrosive gastritis. It also achieves prominent therapeutic effects on stress‑provoked gastric ulcers and upper gastrointestinal hemorrhage.
As a histamine H2‑receptor antagonist, cimetidine suppresses gastric acid secretion stimulated by histamine, alongside secretory responses triggered by food, pentagastrin, caffeine and insulin. It further reduces basal gastric acid output, rendering it suitable for managing gastric ulcers, duodenal ulcers, peptic esophagitis and Zollinger‑Ellison syndrome.
In addition to its well‑documented applications for peptic ulcer disorders, cimetidine functions as an H2 histamine receptor antagonist, an I1‑imidazoline receptor agonist and an anti‑ulcer agent. It impedes cancer cell metastasis by down‑regulating endothelial selectin expression, consequently interfering with tumor‑cell adhesion.
