Nizatidine is a histamine H₂-receptor antagonist (H₂ blocker) used to reduce stomach acid production. It is commonly prescribed for the treatment of:
∙ Gastroesophageal reflux disease (GERD)
∙ Duodenal ulcers
∙ Gastric ulcers
∙ Zollinger-Ellison syndrome
∙ Heartburn and acid indigestion (OTC use in some regions)
Nizatidine works by blocking histamine receptors in the stomach’s parietal cells, which are responsible for acid secretion. This results in decreased gastric acid output, promoting ulcer healing and reducing reflux symptoms.
It is available as oral capsules and oral solutions and is often considered alongside other H₂ blockers like ranitidine, famotidine, and cimetidine.

Nizatidine is used to:
Nizatidine blocks histamine H₂ receptors on the gastric parietal cells, reducing the secretion of hydrochloric acid (HCl) into the stomach. This leads to symptom relief and promotes ulcer healing.
