Drug Study3

Ranitidine is an H2 antagonist used to reduce gastric acid secretion. It is used to treat conditions that raise gastric acid levels such as duodenal ulcers, Zollinger-Ellison syndrome, and GERD. Ranitidine works by reversibly binding to H2 receptors on parietal cells, inhibiting histamine binding and reducing acid secretion. It provides fast relief of gastric acid related symptoms within 60 minutes for 4-10 hours. Ranitidine is administered IV or orally and can be used alone or with antacids to treat various acid-related gastric conditions.
