Sucralfate is a medication primarily used to treat and prevent ulcers in the stomach and intestines. It works by forming a protective layer over the ulcer, shielding it from stomach acid and enzymes, which allows the ulcer to heal. Sucralfate is a basic aluminum salt of sucrose octasulfate.
2. What Conditions Does Sucralfate Treat?
Sucralfate is effective in treating a variety of conditions, both on-label (FDA-approved) and off-label.
- Duodenal Ulcers: Sucralfate is FDA-approved for the short-term treatment (up to 8 weeks) of duodenal ulcers. The typical dosage is 1 gram four times daily for 8 weeks, followed by 1 gram twice daily for maintenance, as noted in research comparable to cimetidine and antacid therapies.
- Dyspepsia: Sucralfate reduces the frequency and intensity of dyspeptic symptoms and gastric erosion during NSAID therapy, showing similar efficacy to H2 receptor blockers.
- Epithelial Wounds: As a topical drug, sucralfate treats epithelial wounds like ulcers, inflammatory dermatitis, mucositis, and burns. Studies, such as one by Tsakayannis et al., show that venous ulcers unresponsive to conventional therapy respond to topical sucralfate.

- Chemotherapy-Induced Mucositis: Sucralfate accelerates growth factor activation, aiding in treating chemotherapy-induced mucositis of the oropharynx and alimentary tract. A study by McCullough suggests administering 1.5 g of sucralfate three times daily at the onset of mucositis for 2 days, followed by 1.5 g twice daily throughout cancer therapy and 2 weeks post-treatment.
- Radiation Proctitis: Sucralfate paste enema has shown clinical improvement in hemorrhagic radiation proctitis treatment, according to research. A study by Kocchar et al. indicates sucralfate enema is superior to oral sulfasalazine in the short-term management of radiation proctitis.
- Prevention of Ulceration of Diversion Colitis: Sucralfate enemas preserve the mucus layer covering the epithelium, reducing inflammation in diversion colitis.
- Stress Ulcer Prophylaxis in Ventilated Patients: Sucralfate is preferred over H2 blockers or antacids in ventilated patients for stress ulcer prophylaxis, as it does not increase the pH of gastric contents, reducing the risk of nosocomial pneumonia.
- Behçet Disease: Topical sucralfate (1 g/5 mL four times daily), alone or combined with topical corticosteroids, reduces pain and promotes the healing of oral ulcers in Behçet disease.
- Gastroesophageal Reflux Disease (GERD): Sucralfate can be used during pregnancy for GERD. The American College of Gastroenterology guidelines support this use.
3. How Does Sucralfate Work?
The exact mechanism of action of sucralfate is not fully understood. However, several actions have been observed in vitro:
- Antipeptic Effects: Sucralfate prevents hydrolysis by preventing enzyme-substrate complex formation, adsorbing pepsin, and decreasing its concentration.
- Site-Protective Effects: Sucralfate forms a polyanion gel, acting as a physical barrier between luminal contents and mucosa, protecting ulcers from acid and pepsin.
- Effects on Mucus: Sucralfate improves mucosal protection by increasing mucus hydrophobicity, viscosity, sulfation, and aluminum and carbohydrate content. It also increases mucus production by boosting prostaglandin production and prevents the breakdown of mucus by pepsin A, reducing ulcerogenesis.
- Effect on Bicarbonate Output: Sucralfate increases prostaglandin-dependent and independent bicarbonate production by the stomach and duodenum.
- Effects on Tissue Growth, Regeneration, and Repair: Sucralfate binds epidermal growth and tissue growth factors to tissues, facilitating repair.
4. What is the Standard Dosage and Administration of Sucralfate?
The dosage and administration of sucralfate vary depending on the condition being treated:
- Oral Dosage Forms:
- Tablet: 1 g tablets, which disintegrate in the stomach and bind to normal and damaged mucosa.
- Suspension: Available as 1 g/10 mL or 500 mg/5 mL.
- Rectal:
- Sucralfate tablets mixed with water to form a paste enema (2 tablets or 2 g of sucralfate mixed with 4.5 mL of water) for hemorrhagic radiation proctitis.
- Topical:
- Used topically for skin conditions and mucosal ulcers.
- Adult Dosing:
- Active Duodenal Ulcers: 1 gram four times daily on an empty stomach for 4 to 8 weeks.
- Maintenance Dosage: 1 g twice daily.
5. What are the Pharmacokinetics of Sucralfate?
- Absorption: Approximately 5% of an orally administered dose is absorbed, with an onset of action within 1 to 2 hours and a duration of action up to 6 hours.
- Distribution: Primarily distributed to lesions in the gastrointestinal tract.
- Metabolism: Degraded into aluminum and sucrose octasulfate in the GI tract without liver or kidney metabolism.
- Elimination: Small amounts of absorbed sulfated disaccharides are excreted in the urine.
6. What are the Potential Side Effects of Sucralfate?
Sucralfate is generally safe due to its local action and minimal absorption. Common side effects include:
- Constipation (1% to 10% of patients)
- Hyperglycemia in diabetic patients
- Nausea, vomiting, flatulence
- Headache, dry mouth, pruritus, skin rash
- Gastric bezoar formation, aluminum intoxication, and hypophosphatemia (rare)
Inadvertent IV use can cause fatal complications like pulmonary emboli and cerebral edema.
Long-term users may retain negligible levels of aluminum, except in cases of renal insufficiency, where uremia can increase aluminum absorption.
7. What are the Drug Interactions with Sucralfate?
Sucralfate can interact with several drugs, decreasing their serum concentrations. Administration should be separated by at least 2 hours from:
- Digoxin
- Levothyroxine
- Furosemide
- Quinolones
- Oral phosphate supplements
- Warfarin
- Antiretrovirals (e.g., raltegravir)
- Bisphosphonates
Antacids taken within 15 minutes of sucralfate can reduce its efficacy. Concurrent administration decreases the bioavailability and concentration of phenytoin and may reduce the serum concentration of quinidine. It may also delay the onset of action of naproxen and affect the absorption of potassium phosphate, leveoketoconazole, deferasirox, and baloxavir.
8. What are the Contraindications for Using Sucralfate?
Contraindications include:
- Documented hypersensitivity to sucralfate or its excipients.
- Relative contraindications include uncontrolled diabetes with hyperglycemia, impaired swallowing/gag reflex, and end-stage renal disease.
A complete medication reconciliation should be performed before initiating sucralfate therapy due to significant drug-drug interactions.
9. What Monitoring is Necessary While Taking Sucralfate?
No specific therapeutic monitoring is typically needed due to minimal absorption. However:
- Blood glucose monitoring may be necessary for diabetic patients.
- Renal function should be monitored in patients with a history of renal impairment.
10. What Should Be Done in Case of a Sucralfate Overdose?
The risks associated with sucralfate overdosing are minimal due to its poor absorption. Most patients remain asymptomatic. However, in patients with chronic kidney disease or those receiving dialysis, aluminum accumulation and toxicity can occur. Serum aluminum levels should be monitored in these patients, and treatment with deferoxamine and EDTA should be considered for aluminum toxicity.

11. What Special Considerations Should Be Taken for Specific Patient Populations?
- Hepatic Impairment: Use with caution. The American Association for the Study of Liver Diseases (AASLD) recommends PPIs or H2 blockers for stress ulcer prophylaxis in patients with acute liver injury, but sucralfate can also be considered.
- Renal Impairment: Use with caution due to documented aluminum accumulation and toxicity.
- Pregnancy: Sucralfate is generally considered safe during pregnancy due to minimal systemic absorption.
- Breastfeeding: It is considered safe during breastfeeding due to minimal absorption; no precautions are necessary.
- Pediatric Patients: Use with caution. Topical sucralfate is used off-label in pediatric patients with adenotonsillectomy to reduce oropharyngeal pain.
- Older Patients: Use with caution as sucralfate can reduce the absorption of other medications. Renal function monitoring is also recommended.
12. What is the Role of Interprofessional Team Coordination in Sucralfate Therapy?
Effective management of conditions treated with sucralfate requires interprofessional team coordination. Physicians, nurse practitioners, and physician assistants prescribe the medication, while nurses provide patient counseling and coordinate refills. Pharmacists check dosing and frequency, provide additional counseling, watch for adverse events, and contact the prescriber with any concerns. Gastroenterologist consultation is necessary for refractory peptic ulcer disease, and critical care physicians and toxicologists should be consulted for accidental overdose.
