Why is this medication prescribed?

Ranitidine is a medication that belongs to a class of drugs known as H2 blockers. It is commonly prescribed for the treatment of conditions related to excess stomach acid production. 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 upper part of the small intestine).
• Gastroesophageal Reflux Disease (GERD): It is used to treat GERD, a condition in which stomach acid regularly flows back into the esophagus, causing irritation and heartburn.
• Zollinger-Ellison Syndrome: This is a rare condition where the stomach produces too much acid. Ranitidine can help manage the excessive acid production associated with this syndrome.
• Erosive Esophagitis: Ranitidine may be prescribed to treat erosive esophagitis, which is inflammation and damage to the esophagus caused by stomach acid.

Ranitidine works by blocking the action of histamine on certain cells in the stomach, reducing the production of acid.

How should this medicine be used?

As for how ranitidine should be used, it is typically taken orally, either with or without food.
