Funide Iron and Vitamin Sustained‑Release Tablets

1. Indications and Usage
Combined Anemia: Indicated for the treatment of iron deficiency anemia and vitamin deficiency anemia caused by poor nutrition, malabsorption, or chronic blood loss.
Prevention: Used to prevent nutrient depletion in patients with increased requirements, such as during pregnancy, lactation, or recovery from chronic illness.
2. Dosage and Administration
Standard Dose: The usual dosage for adults is 1 tablet once or twice daily, taken orally.
Administration: To minimize gastric irritation, the tablet should be taken after meals. The sustained-release formulation allows for gradual nutrient release.
Duration: Treatment should continue for at least 3–6 months after hemoglobin levels normalize to replenish iron stores and vitamin reserves.
3. Mechanism of Action
Heme and Enzyme Synthesis: Iron serves as the core component of hemoglobin for oxygen transport, while vitamins (such as B-complex and C) act as cofactors in erythropoiesis and iron metabolism.
Synergistic Effect: The combination facilitates the synergistic synthesis of red blood cells, correcting the dual deficits of oxygen transport capacity and cellular metabolism.
4. Safety and Warnings
Gastrointestinal Tolerance: Although the sustained-release formulation reduces gastric irritation, patients with active peptic ulcers should use it with caution.
Iron Overload: Contraindicated in patients with hemochromatosis, hemosiderosis, or other disorders of iron metabolism.
Pediatric Safety: Keep out of reach of children, as iron overdose can be fatal in young children.
5. Adverse Reactions and Clinical Research
Common Adverse Reactions: Black stools (harmless), nausea, epigastric discomfort, constipation, or diarrhea.
Hypersensitivity: Occasional skin rashes or pruritus may occur.
Clinical Findings: Clinical evidence supports the efficacy of combination formulations in accelerating the recovery of hemoglobin levels compared to single-nutrient supplementation.
6. Drug Interactions
Antacids: Aluminum-containing antacids decrease iron absorption.
Tetracyclines/Quinolones: Iron decreases the absorption of these antibiotics.
Levodopa: Iron may reduce the efficacy of levodopa.
Folic Acid: Concurrent use may enhance the hematologic response.
7. Pharmaceutical Information
Active Ingredient: Iron salts and essential vitamins (specific composition varies by manufacturer).
Strengths: Typically available as single-dose tablets containing standardized amounts of elemental iron and vitamins.
Appearance: Various colors depending on the coating, often film-coated to control release.
Storage: Store in a tight, light-resistant container, protected from moisture and heat.
