- Subcutaneous injection
- 250–500mcg
- Twice daily (every 12 hours)
- ~95% (bypasses first-pass)
- 14–21 days to complete mucosal closure
- Gold standard for acute ulcer protocols. Maintains therapeutic levels continuously, fastest healing rates in published models
- Oral administration
- 500–1000mcg
- Once daily (fasted state)
- ~30–40% (survives gastric acid but undergoes intestinal degradation)
- 21–28 days to complete mucosal closure
- Emerging option for maintenance or prevention. Less invasive but requires higher doses to compensate for lower absorption
- Intramuscular injection
- Twice daily
- ~90% (slightly slower absorption than SC)
- 14–21 days (comparable to SC)
- No advantage over subcutaneous route. Higher injection discomfort without efficacy benefit
- Topical/intranasal
- Variable (poorly studied)
- Not established
- <10% (minimal systemic absorption)
- Not established in ulcer models
- Insufficient evidence for gastric ulcer healing. May have utility in oral mucosal lesions but lacks controlled trial data
