A Cal Tablet contains Calcium Carbonate. A Cal Tablet is used for:
Adult: One A Cal Tablet 500 tablet or as directed by the physician. For the prevention of osteoporosis, 1-3 A Cal Tablet 500 tablet is recommended generally as a dietary supplement . Doses for children is half of those for adults. A large dose should not be taken without physician\'s advice.
Adolescent: One to two A Cal Tablet tablet daily.
Children: One A Cal Tablet tablet daily.
Calcium carbonate reacts with gastric acid to produce a salt and water. For A Cal Tablet the postulated chemical reaction is:
CaCO3 + 2HCl = CaCl2 + H2O + CO2
Indicated in raised calcium requirement e.g. during pregnancy and lactation, and in children and adolescents at time of rapid growth, inadequate intake of calcium in the diet due to malnutrition, prevention and treatment of osteoporosis, disorders of osteogenesis and tooth formation, latent tetany.
Minerals in bone formation, Specific mineral preparations
A Cal Tablet is always used orally and when used as an antacid the recommended doses for adults are equivalent to 540-2000 mg A Cal Tablet 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 Tablet (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 Tablet per day and need to be adjusted according to the individual patient. To maximize effective phosphate binding in this context the A Cal Tablet should be given with meals.
In rare cases, flatulence, diarrhoea or constipation.
In the presence of mild hypercalciuria, excretion levels must be carefully monitored and where necessary the dose of A Cal Tablet should be reduced or treatment should be stopped. Patients with a history of stone formation should also be recommended to increase their fluid intake. High dosage of vitamin D should be avoided during Calcium therapy unless specifically indicated.
Oral calcium can reduce internal absorption of tetracycline and fluoride prepa-rations and an interval of at least 3 hours should therefore be allowed between ingestion of these medications. Vitamin D increases internal absorption of calcium. The intestinal uptake of calcium may be reduced by concomitant ingestion of certain foods (e.g. spinach, milk and milk products).
Pregnant women : Calcium containing drugs are used widely in pregnancy by way of calcium supplement or antacid therapy. No relationship between malformation in general and calcium exposure has been noted.
Lactating mother : There is no contraindication to the use of A Cal Tablet in lactating mother.
Hypersensitivity to the A Cal Tablet or any inactive ingredient of the medication. Hypercalcemia (e.g. in hyperparathyroidism, overdosage of vitamin D, demineralizing tumours such as plasmacytomas and bone metastases), severe hypercalcuria, several renal insufficiency.
Store in a cool, dry place in controlled room temperature.
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 Tablet 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.
