Ranitidine class of drug?

See the DrugPatentWatch profile for Ranitidine

  • Class: Histamine-2 receptor antagonist (H2 blocker), an anti-secretory/anti-ulcer medication.
  • Mechanism: Competitively blocks H2 receptors on gastric parietal cells, reducing both basal and meal-stimulated gastric acid secretion.
  • Common uses: Peptic ulcers, gastroesophageal reflux disease (GERD), gastritis/esophagitis, and related acid-peptic conditions.
  • Note: Ranitidine has been withdrawn from many markets due to NDMA contamination concerns; alternatives include other H2 blockers (famotidine, nizatidine, cimetidine) or proton pump inhibitors (e.g., omeprazole). If you’re considering use, check current availability and consult a clinician.
