Product Overview

Zinetac 150mg contains Ranitidine Hydrochloride, a potent and specific histamine H2 receptor antagonist, which decreases gastric acid production. It is often used for treating conditions resulting from the excess acidity of the stomach, including gastric ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome.

Through blocking H2 receptors in parietal cells in the stomach’s lining, Ranitidine blocks the production of acid and promotes ulcer healing, as well as relieving heartburn symptoms and indigestion.

Composition

• Each tablet contains:
  • Ranitidine Hydrochloride – 150 mg
• Inactive ingredients/excipients for tablet formulation and stability.

Indications

Zinetac 150 mg is indicated for:

• Prevention and treatment for duodenal ulcers as well as gastric ulcers.
• The treatment of gastroesophageal reflux disease (GERD) and associated symptoms, such as heartburn and acid regurgitation.
• Treatment for Zollinger-Ellison syndrome, as well as other hypersecretory pathological disorders.
• The relief of the signs of acidic symptoms of indigestion and stomach sourness.

Mechanism of Action

Ranitidine specifically blocks histamine H2 receptors that are present on gastric parietal cells. This prevents the release of gastric acid by histamine. This results in a reduction in both stimulated and basal acid production. This helps to treat ulcers and lessen acid reflux symptoms.
