Why is this medication prescribed?

Ranitidine is a medication that belongs to a class of drugs known as H2 blockers. It is commonly prescribed to treat conditions related to excessive stomach acid production. Some of the main uses of ranitidine include:

  • Gastric and Duodenal Ulcers: Ranitidine is often prescribed to heal and prevent ulcers in the stomach and duodenum (the first part of the small intestine). It works by reducing the amount of acid produced by the stomach.
  • Gastroesophageal Reflux Disease (GERD): GERD is a condition in which stomach acid flows back into the esophagus, causing irritation and symptoms like heartburn. Ranitidine can help alleviate these symptoms by reducing acid production.
  • Zollinger-Ellison Syndrome: This is a rare condition where the stomach produces too much acid. Ranitidine can be used in such cases to control excessive acid production.
  • Erosive Esophagitis: Ranitidine can be prescribed to treat inflammation and damage to the esophagus caused by stomach acid.
