Usage
Sucralfate + Zinc Carnosine is prescribed for the treatment of peptic ulcer disease, including gastric and duodenal ulcers. Zinc Carnosine may also be beneficial for gastritis and esophagitis. It acts as a mucosal protectant, offering antioxidant and anti-inflammatory effects.
It’s pharmacological classifications are:
-
Mucosal Protectant: Sucralfate forms a physical barrier over ulcers, protecting them from gastric acid.
-
Antioxidant/Anti-inflammatory: Zinc Carnosine contributes to mucosal defense and healing.
Alternate Names
- Polaprezinc
- Zinc-L-carnosine
- Z-103
Brand names include Sucratab Z, Carnozin SF, and Carnoz S.
How It Works
Pharmacodynamics:
-
Sucralfate: In the acidic environment of the stomach, Sucralfate forms a viscous, sticky paste that binds to the ulcer site. This creates a protective barrier against pepsin, gastric acid, and bile salts, facilitating ulcer healing.
-
Zinc Carnosine: While the exact mechanism is unclear, it’s thought to enhance mucosal integrity, exert antioxidant and anti-inflammatory effects, and promote growth factors involved in tissue repair.
Pharmacokinetics:
-
Sucralfate: Minimally absorbed systemically, primarily acting locally in the gastrointestinal tract. Excreted mainly in feces.
-
Zinc Carnosine: Dissociates into zinc and carnosine in the GI tract. Zinc absorption is influenced by dietary factors and body stores. Carnosine is metabolized by the enzyme carnosinase, predominantly in the kidneys.
Mode of Action/Receptor binding, enzyme inhibition, neurotransmitter modulation: Not fully understood, but believed to involve enhanced mucosal defense, antioxidant activity, and modulation of inflammatory mediators. No specific receptor binding or enzyme inhibition has been identified.
Dosage
Standard Dosage
Adults:
- Sucralfate: 1 gram four times daily on an empty stomach, one hour before meals and at bedtime.
- Zinc Carnosine: 75 mg twice daily.
Children:
- Sucralfate: Use and dose must be determined by a doctor.
- Zinc Carnosine: Safety and efficacy haven’t been established in children under 12. Dosage reduction may be necessary, but pediatric consultation is crucial.
Special Cases:
- Elderly Patients: Zinc Carnosine: 100 mg once daily may be considered.
- Patients with Renal Impairment: Sucralfate: Use with caution due to potential aluminum accumulation. Zinc Carnosine: Careful dose adjustment is required.
- Patients with Hepatic Dysfunction: Zinc Carnosine: Caution is advised, with liver function monitoring recommended.
- Patients with Comorbid Conditions: Diabetes: Monitor blood glucose, especially with Sucralfate suspension.
Clinical Use Cases
Dosage recommendations for specific clinical settings (intubation, surgical procedures, mechanical ventilation, ICU, emergencies) aren’t well-established for this combination. Standard dosages are usually followed unless contraindications exist.
Dosage Adjustments
Dose adjustments are recommended based on renal/hepatic function and other relevant factors.
Side Effects
Common Side Effects
- Constipation
- Nausea
- Dizziness
- Sleepiness
Rare but Serious Side Effects
Bezoar formation (primarily with Sucralfate)
Long-Term Effects
Data on long-term effects are limited.
Contraindications
Hypersensitivity to Sucralfate or Zinc Carnosine. Use cautiously in patients with renal impairment (Sucralfate) and patients with copper deficiency (Zinc Carnosine).
Drug Interactions
- Sucralfate: Can interfere with the absorption of certain medications (e.g., digoxin, fluoroquinolones, tetracycline). Administer other drugs at least two hours before or after Sucralfate. Antacids can decrease Sucralfate’s effectiveness if taken within 30 minutes of each other.
- Zinc Carnosine: Potential interaction with quinolone antibiotics. Food may reduce potential interactions.
Pregnancy and Breastfeeding
-
Sucralfate is generally considered safe during pregnancy and breastfeeding due to minimal systemic absorption.
-
Data on Zinc Carnosine use during pregnancy and breastfeeding are limited; not recommended without a doctor’s advice.
Drug Profile Summary
- Mechanism of Action: Sucralfate forms a protective barrier over ulcers. Zinc Carnosine supports mucosal defense.
- Side Effects: Constipation, nausea, dizziness, sleepiness.
- Contraindications: Hypersensitivity, renal impairment (Sucralfate).
- Drug Interactions: See above.
- Pregnancy & Breastfeeding: Sucralfate: Generally safe. Zinc Carnosine: Not recommended.
- Dosage: See above.
- Monitoring Parameters: Renal function (Sucralfate), liver function (Zinc Carnosine), blood glucose (especially in diabetics using Sucralfate suspension).
Popular Combinations
Sucralfate is sometimes used in combination with proton pump inhibitors (PPIs) for treating ulcers, although there are specific dosing intervals to observe.
Precautions
- Ensure adequate hydration to prevent constipation.
- Monitor for bezoar formation (Sucralfate).
- Avoid concomitant use of antacids with Sucralfate.
