์์ฉ ๊ธฐ์ : When administered with meals, calcium acetate dissociates in the gastrointestinal tract. The calcium ions then bind to dietary phosphorus in the stomach and proximal small intestine to form **calcium phosphate**, an insoluble complex. Dietary Phosphorus + Calcium Acetate โ **Insoluble Calcium Phosphate** โ Excreted in feces. This mechanism effectively reduces the gastrointestinal absorption of phosphorus, thereby lowering serum phosphorus levels. It is soluble over a wide range of pH, making it highly available for binding.

- Hyperphosphatemia associated with chronic renal failure ยท 60-90 mg/kg/day ยท PO ยท divided with meals ยท In conjunction with a low-phosphorus diet. Give with food or mixed with food, or just prior to each meal. Individualize dose to achieve desired serum phosphorus concentrations. Decrease dose if serum calcium exceeds normal limits.
- Hyperphosphatemia in CKD ยท 60-90 mg/kg/day divided ยท PO ยท divided with meals ยท Long-term ยท Dose must be titrated based on serum phosphorus levels. Must be given with food.

- Calcitriol ยท May lead to hypercalcemia; if used concomitantly, intensified monitoring for hypercalcemia is mandatory.
- Digoxin ยท Not recommended; hypercalcemia induced by calcium acetate may cause serious arrhythmias in patients on digoxin.
- Fluoroquinolones ยท Oral calcium can reduce the absorption of fluoroquinolones. Separate dosages by at least two hours. ยท major
- Tetracyclines ยท Oral calcium can reduce the absorption of tetracyclines. Separate dosages by at least two hours. ยท major
- Levothyroxine ยท Decreased absorption of levothyroxine ยท moderate

- Monitor initially at 10-14 day intervals; once 'stable', at 4-6 week intervals

Acute overdoses could potentially cause **hypercalcemia**. - **Management:** Patients should be monitored and treated symptomatically. - If the dosage was massive and recent, consider using standard protocols to empty the gut (e.g., emesis induction or gastric lavage, followed by activated charcoal, though charcoal does not bind minerals well).
