Ranitidine oral uses?

Ranitidine taken by mouth is an H2 receptor antagonist that reduces stomach acid. Oral uses include:

- Active peptic ulcers (gastric and duodenal) and prevention of recurrence
- GERD (gastroesophageal reflux disease) and healing of erosive esophagitis
- Symptomatic relief of acid-related dyspepsia, heartburn, and acid indigestion
- Zollinger-Ellison syndrome (gastrin-secreting tumors) where acid overproduction occurs
- In some settings, historical/region-specific regimens for H. pylori–related ulcers (less common today)

Note: In many places, ranitidine products have been recalled or withdrawn from the market due to concerns about a nitrosamine contaminant (NDMA). If you’ve been prescribed ranitidine, or if you’re considering it, check with a healthcare provider about current approved alternatives (e.g., famotidine, nizatidine, or proton pump inhibitors like omeprazole) and follow local regulatory guidance.
