Ferric Sodium Edetate Granules: Manufacturing Process and Applications

Ferric sodium edetate granules are a highly effective iron supplement used to treat iron deficiency anemia. The fabrication process ensures optimal bioavailability and stability, making it a preferred choice in pharmaceuticals. This article explores the key steps in manufacturing ferric sodium edetate granules and their benefits.

1. Raw Material Preparation
The production begins with high-purity ferric chloride and sodium edetate (EDTA). These compounds undergo strict quality checks to ensure compliance with pharmacopeial standards.

2. Synthesis of Ferric Sodium Edetate Complex
The ferric chloride solution is slowly mixed with sodium edetate under controlled pH (3.5–4.5) and temperature (40–50°C). This forms a stable ferric sodium edetate complex, which is then purified through crystallization.

3. Granulation Process
The dried complex is blended with excipients like microcrystalline cellulose and binders. Wet granulation is commonly used, where the mixture is moistened with a solvent (e.g., ethanol-water) and passed through a sieve to form uniform granules.

4. Drying and Sizing
The granules are dried in a fluidized bed dryer to remove residual moisture. After drying, they are sieved to achieve a consistent particle size (typically 0.5–1.5 mm).

5. Quality Control and Packaging
Final products undergo rigorous testing for iron content, dissolution rate, and microbial limits. Once approved, the granules are packed in moisture-resistant containers to ensure long-term stability.

Applications of Ferric Sodium Edetate Granules
– Pharmaceuticals: Used in oral iron supplements for better absorption.
– Food Fortification: Added to cereals and nutritional powders.
– Veterinary Medicine: Treats iron deficiency in livestock.

Conclusion
The fabrication of ferric sodium edetate granules involves precise chemical synthesis and granulation techniques to ensure high efficacy and safety. Its superior bioavailability makes it a valuable solution for iron supplementation.
