# Sucralfate (Sucrafil O Gel)
## Overview
Sucralfate is a basic aluminum salt of sulfated disaccharide that exerts a local cytoprotective effect. In acidic environments (pH <4), it forms a viscous, paste-like complex that adheres to ulcer craters, protecting the mucosa from acid, pepsin, and bile salts.
## Primary Indications
* Short-term treatment (up to 8 weeks) of active duodenal ulcers.
* Off-label: Gastric ulcers, GERD, stress ulcer prophylaxis, and oral mucositis/stomatitis (frequently utilized in the oral gel formulation).
## Adult Dosing
* **Duodenal Ulcer:** 1 gram orally 4 times daily (on an empty stomach) OR 2 grams orally twice daily. Maximum: 8 grams/day.
* **Maintenance (Duodenal Ulcer):** 1 gram orally twice daily.
* **Oral Mucositis:** 5–10 mL (swish and swallow) 4 times daily as directed by local institutional protocols.
## Pediatric Dosing
* **Stress Ulcer Prophylaxis / GERD:** 40–80 mg/kg/day divided into 4 doses.
* *Note:* Dosing is infant/child-weight dependent; consult the specific institutional formulary for standardized mg/mL concentrations.
## Dose Adjustments
* **Renal Impairment:** Use with caution in patients with chronic kidney disease (CKD) due to the risk of aluminum accumulation/toxicity. No formal dose adjustment guidelines, but monitor aluminum levels if used long-term in severe renal impairment.
* **Hepatic Impairment:** No adjustments required.
## Contraindications
* Hypersensitivity to sucralfate or any component of the formulation.
## Adverse Effects
* **Common:** Constipation (most frequent).
* **Rare:** Diarrhea, nausea, gastric discomfort, dry mouth, pruritus, back pain, and dizziness.
* **Potential Risk:** Aluminum toxicity in patients with renal failure (encephalopathy, osteomalacia).
## Key Drug Interactions
Sucralfate significantly impairs the absorption of many drugs due to its binding properties.
* **Commonly affected:** Fluoroquinolones, tetracyclines, levothyroxine, phenytoin, ketoconazole, and warfarin.
* **Guidance:** Administer other medications at least **2 hours before or after** sucralfate.
## Monitoring
* Monitor for symptom relief and resolution of ulcer pain.
* In patients with renal insufficiency, monitor serum aluminum and phosphate levels if therapy exceeds 2 weeks.
## Clinical Pearls
* **Administration:** Must be taken on an empty stomach (1 hour before or 2 hours after meals). Efficacy is significantly reduced if taken with food or antacids within 30 minutes.
* **Oral Gel:** Sucrafil O Gel is specifically designed for local coating of the oral mucosa; instruct patients to swish the gel thoroughly in the mouth before swallowing for mucositis.
* **Duration:** Do not use for longer than 8 weeks unless directed by a physician.
