Sucralfate Therapy
Primary and Secondary Indications
- The American Gastroenterological Association recommends sucralfate as a second-line agent for stress ulcer prophylaxis in critically ill patients, particularly when H2-blockers or PPIs cannot be used 1, 2
- Sucralfate enemas can be used for radiation proctitis with heavy bleeding as a temporary or long-term treatment for patients unsuitable for disease-modifying therapy, as suggested by the European Society for Medical Oncology 3
Clinical Considerations
- The Centers for Disease Control and Prevention note that when used for stress ulcer prophylaxis, sucralfate may be associated with lower risk of nosocomial pneumonia compared to H2-blockers or PPIs that increase gastric pH 4
- Administer sucralfate at least 2 hours apart from drugs that decrease gastric acidity to avoid interaction, as recommended by the American College of Gastroenterology 5
Dosage and Administration
- For radiation proctitis, the standard dosage is 2g sucralfate suspension mixed with 30-50mL water administered rectally as an enema, twice daily initially, then once daily for maintenance, as recommended by the National Comprehensive Cancer Network 3
Sucralfate Evidence Review
Guideline Recommendations
- The European Society for Medical Oncology (ESMO) guidelines explicitly recommend against oral sucralfate for radiation-induced gastrointestinal mucositis, stating it does not prevent acute diarrhea in patients with pelvic malignancies and is associated with more gastrointestinal side effects, including rectal bleeding, compared to placebo 6, 7
- The British Society of Gastroenterology guidelines support sucralfate enemas (not oral) for radiation proctitis, with a dosing regimen of 2g sucralfate suspension mixed with 30-50mL water, administered rectally, and a frequency of twice daily initially, then once daily for maintenance 8, 9
- The British Society of Gastroenterology guidelines indicate that sucralfate enemas are used for chronic radiation-induced proctitis with rectal bleeding 6, 7
