Sucralfate Clinical Uses in Gastrointestinal Diseases
Sucralfate is widely recognized for its role as a cytoprotective agent in the management of various gastrointestinal conditions. It is FDA-approved for the treatment of duodenal ulcers and is also used for gastric ulcers, gastroesophageal reflux disease (GERD), and non-erosive reflux disease (NERD) Bq2022Lam1994Wayne2020. Sucralfate works by forming a protective barrier over ulcer sites, shielding the mucosa from acid, bile, and pepsin, and promoting healing. In patients taking nonsteroidal anti-inflammatory drugs (NSAIDs), sucralfate has been shown to significantly reduce gastrointestinal symptoms and mucosal damage, allowing continued NSAID therapy with fewer complications . Newer formulations, such as pre-polymerized sucralfate, have demonstrated even greater mucosal protection in GERD and NERD .
Topical Sucralfate for Epithelial and Mucocutaneous Wound Healing
Beyond its gastrointestinal uses, sucralfate has been increasingly applied topically for various epithelial wounds and mucocutaneous conditions. Clinical evidence supports its effectiveness in promoting healing of ulcers, burns, inflammatory dermatitis, and mucositis Masuelli2009Abtahi-Naeini2022Chittoria2024. Topical sucralfate is beneficial in managing post-radiotherapy reactions, diaper dermatitis, keratoconjunctivitis sicca, peristomal wound infections, and other mucocutaneous inflammatory and infectious disorders . It is also used to relieve pain and accelerate wound healing after surgical procedures such as haemorrhoidectomy, where it significantly reduces pain, decreases the need for analgesics, and improves wound healing rates compared to placebo .
Sucralfate in Oral and Periodontal Health
Sucralfate has shown promise as an adjunctive therapy in oral health, particularly in the prevention and management of oral mucositis induced by radiation therapy in patients with head and neck cancers . It reduces mucositis severity, oral pain, and histopathological signs of tissue damage. In periodontal disease, sucralfate’s cytoprotective, anti-inflammatory, and antibacterial properties help form protective barriers, reduce inflammation, and promote wound healing, making it a potential adjunct in periodontal therapy and postoperative recovery .
Safety and Tolerability of Sucralfate
Sucralfate is generally considered safe, with minimal systemic absorption and a low risk of adverse effects. The most common side effect is constipation, and rare cases of aluminum toxicity have been reported in patients with renal impairment Abtahi-Naeini2022Savitri2025. Topical applications are well-tolerated and have not been associated with significant adverse effects in clinical studies Abtahi-Naeini2022Etiz2000.
Conclusion
Sucralfate is a versatile agent with established clinical uses in the treatment of gastrointestinal ulcers, GERD, and NSAID-induced mucosal injury. Its topical application extends its benefits to a range of epithelial and mucocutaneous wounds, including burns, ulcers, and post-surgical wounds, as well as oral and periodontal conditions. Sucralfate’s safety profile and multiple mechanisms of action make it a valuable option in both systemic and topical therapies, though further research is needed to standardize its use in newer indications Bq2022Masuelli2009Lam1994+7 MORE.
