Beyond infusion solutions and bioprocessing, acetates exhibit unique physicochemical properties that are valuable in solid dosage form manufacturing.
Tablet manufacturing
Sodium acetate trihydrate can be used as a specialized hydrophilic binder and disintegrant in effervescent tablets and other sensitive oral formulations.
During dry granulation or the direct compression of highly pressure-sensitive APIs, sodium acetate acts as a soluble matrix-forming agent and binder under mild compression forces.
It provides a highly crystalline framework that deforms plastically under pressure, protecting brittle API crystals from mechanical fracture while enabling the production of mechanically stable tablets.
Phosphate binding
Calcium acetate is formulated into oral tablets and capsules as a highly effective phosphate binder for the management of hyperphosphatemia.
When taken with meals by patients with chronic kidney disease, calcium ions dissociate in the gastrointestinal tract and react with dietary phosphate to form insoluble calcium phosphate complexes.
These complexes are safely excreted in the feces, effectively reducing serum phosphate levels.
