Ranitidine

Antacid

Uses of Ranitidine

Ranitidine is a histamine H2-receptor antagonist used to reduce the amount of acid produced in the stomach.
It is commonly used for:
• Peptic ulcers: Treats and helps prevent stomach and duodenal ulcers by reducing acid that irritates the ulcer.
• Gastro-oesophageal reflux disease (GERD): Relieves heartburn, acid regurgitation, and indigestion caused by acid reflux.
• Zollinger-Ellison syndrome: Manages excess stomach acid production caused by this rare condition.
• Scleroderma oesophagitis: Reduces acid-related damage to the oesophagus in this condition.

Side effects of Ranitidine

  • Dizziness, light-headedness or drowsiness
  • Headache
  • Muscle or joint pain
  • Constipation or diarrhoea
  • feeling sick (nausea) or vomiting
  • Sexual problems
  • Difficulty sleeping
  • Abdominal pain
  • Blurred vision.

How Ranitidine works

  • Ranitidine works by blocking histamine H2 receptors on acid-producing cells in the stomach lining, reducing the amount of acid released.
  • Certain cells in the stomach lining, called parietal cells, release acid in response to histamine binding to H2 receptors. Ranitidine blocks these receptors, preventing histamine from triggering acid release.
  • This lowers the acidity in the stomach, easing symptoms such as heartburn and indigestion, and helping ulcers to heal.

Special Dietary & Lifestyle Recommendation

Opting for low-acid foods and avoiding triggers such as spicy, acidic, or fatty foods can be beneficial. Additionally, refraining from consuming large meals close to bedtime can minimise the likelihood of reflux symptoms. Steering clear of tobacco and limiting alcohol intake are advisable, as both can exacerbate digestive issues.
