Generic Medicine Info
Indications and Dosage
Oral
Hyperphosphataemia
Adult: Control of hyperphosphataemia in ESRD: Initially, 4-8 g (1-2 g Ca) daily in divided doses, adjusted according to serum phosphate concentrations. Max: 12 g (3 g Ca) daily.
Administration
Should be taken with food.
Contraindications
Hypercalcaemia, renal calculi.
Special Precautions
Patient with hypercalcaemia-associated diseases (e.g. sarcoidosis, and other malignancies); risk factors for cardiac arrhythmias, hypoparathyroid disease. Renal impairment. Pregnancy.
Adverse Reactions
Significant: Hypercalcaemia, constipation, bloating and gas.
Gastrointestinal disorders: Nausea, vomiting.
Monitoring Parameters
Monitor serum Ca (twice weekly during initial dose adjustments); serum phosphorus; serum Ca-phosphorus product; intact parathyroid hormone.
Drug Interactions
Increased risk of cardiac arrhythmias with digitalis, verapamil, gallopamil in the presence of hypercalcaemia. May decrease the bioavailability of fluoroquinolones (e.g. ciprofloxacin), and tetracyclines (e.g. doxycycline).
Action
Description:
Mechanism of Action: Ca acetate sequesters phosphate in the small intestine to form insoluble calcium phosphate, which is excreted in the faeces, thereby reducing phosphate absorption in the gut and preventing the development of renal osteodystrophy in chronic renal failure.
Pharmacokinetics:
Absorption: Primarily absorbed from the small intestine via active transport and passive diffusion, vitamin D enhances absorption.
Distribution: Crosses the placenta and enters the breast milk.
Excretion: Mainly via faeces (as insoluble calcium salts); urine (20%).
