# Sucralfate (Sucrafil O Gel)
## Overview
Sucralfate is a basic aluminum salt of sulfated disaccharide. It acts locally by forming a viscous, adhesive complex that binds to proteins in necrotic ulcer tissue, creating a physical barrier against gastric acid, pepsin, and bile salts. Sucrafil O Gel often includes oxetacaine (a local anesthetic) to provide rapid symptomatic relief of pain associated with mucosal irritation.
## Primary Indications
* Duodenal ulcers (short-term treatment).
* Gastroesophageal reflux disease (GERD) and gastritis management.
* Symptomatic relief of oral/esophageal mucositis or peptic ulcer pain.
## Adult Dosing
* **Duodenal Ulcer:** 1 gram (10 mL of standard suspension) four times daily, 1 hour before meals and at bedtime.
* **Maintenance:** 1 gram twice daily.
* **Maximum Dose:** 8 grams/day.
* *Note:* Duration for acute ulcers is typically 4–8 weeks.
## Pediatric Dosing
* **General Range:** 40–80 mg/kg/day divided into 4 doses.
* *Caution:* Safety and efficacy in children are not fully established; use under specialist guidance only. Dosing depends heavily on local institutional protocols.
## Dose Adjustments
* **Renal Impairment:** Use with extreme caution. Aluminum accumulation can occur in patients with chronic kidney disease; monitor closely.
* **Hepatic Impairment:** No specific adjustment required; however, minimize use in patients with severe hepatic dysfunction if risk of encephalopathy (due to aluminum) is suspected.
## Contraindications
* Hypersensitivity to sucralfate or any component of the formulation (e.g., oxetacaine).
* Severe renal impairment (risk of aluminum toxicity).
## Adverse Effects
* **Common:** Constipation (most frequent), nausea, dry mouth.
* **Rare:** Bezoar formation (especially in critically ill or tube-fed patients), aluminum toxicity (in renal patients), hypersensitivity reactions.
## Key Drug Interactions
Sucralfate interferes with the absorption of many medications by forming a physical barrier.
* **Binders:** Separate administration by at least 2 hours from: Fluoroquinolones, Tetracyclines, Phenytoin, Levothyroxine, Ketoconazole, and Digoxin.
* **Antacids:** Administer at least 30 minutes before or after sucralfate to maintain the acidic environment required for sucralfate activation.
## Monitoring
* **Efficacy:** Symptom resolution (pain, heartburn).
* **Safety:** Monitor for constipation. Monitor serum aluminum levels in patients with impaired renal function if therapy exceeds 2 weeks.
* **Toxicity:** Signs of neurotoxicity (if renal impairment is present).
## Clinical Pearls
* **Timing is critical:** Sucralfate requires an acidic environment to bind effectively to ulcer sites; avoid using with PPIs, H2-blockers, or antacids simultaneously.
* **Gel Formulations:** Products like "Sucrafil O" containing oxetacaine should not be used in children under 12 without strict assessment due to the risk of anesthetic-related side effects.
* **Administration:** It is not a systemic drug; its efficacy is strictly local.
* **Tube Feeding:** Avoid administering via feeding tubes if possible, as it is highly prone to clogging the tube.
