Pharmacology
Calcium carbonate reacts with gastric acid to produce a salt and water.
Absorption
The increase in gastric pH diminishes the activity of pepsin in the gastric secretion. Up to 30% of the oral calcium load may be absorbed.
Dosage & Administration of A-Cal 250 mg
250 mg or 500 mg tablet: A-Cal 250 mg is always used orally and when used as an antacid the recommended doses for adults are equivalent to 540-2000 mg A-Cal 250 mg per day, doses for children being half of those for adults. As a dietary supplement, such as for the prevention of osteoporosis, 1250-3750 mg A-Cal 250 mg (500-1500 mg calcium) daily is recommended in general, but again this will need to be tailored to the individual patient depending on any specific disease such as Calcium deficiency, malabsorption or parathyroid function. In pregnancy and lactation the recommended daily dose of calcium is 1200-1500 mg. In chronic renal failure the doses used vary from 2.5-9.0 gm A-Cal 250 mg per day and need to be adjusted according to the individual patient. To maximize effective phosphate binding in this context the A-Cal 250 mg should be given with meals.1000 mg tablet: 2000-3000 mg tablet when symptoms occur; may be repeated hourly if needed or as directed by the physician.
Interaction of A-Cal 250 mg
A-Cal 250 mg may enhance the cardiac effects of digoxin and other cardiac glycosides, if systemic hypercalcaemia occurs. A-Cal 250 mg may interfere with the absorption of concomitantly administered tetracycline preparations and in chronic renal failure modification of vitamin D therapy may be required to avoid hypercalcaemia when A-Cal 250 mg is used as the primary phosphate binder.
Contraindications
Hypercalcaemia and hyperparathyroidism
Hypercalciuria and nephrolithiasis
Zollinger-Ellison syndrome
Concomitant digoxin therapy (requires careful monitoring of serum calcium level)
When hypercalcaemia occurs, discontinuation of the drug is usually sufficient to return serum calcium concentrations to normal. Calcium salts should be used cautiously in patients with sarcoidosis, renal or cardiac disease, and in patients receiving cardiac glycosides.
Side Effects of A-Cal 250 mg
Orally administered A-Cal 250 mg may be irritating to the GI tract. It may also cause constipation. Hypercalcaemia is rarely produced by administration of calcium alone, but may occur when large doses are given to patients with chronic renal failure.
Pregnancy & Lactation
Calcium containing drugs have been widely used in pregnancy by way of oral calcium supplementation or antacid therapy. A-Cal 250 mg can be used in lactating women too.
Storage Conditions
Store in a cool, dry place in controlled room temperature.
Use In Special Populations
Use in children: Calcium carbonate has been extensively studied in children and infants with chronic renal failure and is both safe and effective.Use in elderly: In case of elderly patients with renal failure when A-Cal 250 mg is taken constipation may be troublesome one for this group. For this reason, monitoring of serum calcium and phosphate is of course indicated for elderly patients.
