Ostogen® 500 Each capsule contains 500 mg calcium carbonate.
Calcium is best known for its role in maintaining the strength and density of bone.
Mode of Action:
Calcium and phosphorus join to form calcium phosphate. Calcium phosphate is a major component of the mineral complex (called hydroxyapatite) that gives structure and strength to bones, Calcium also plays a role in many physiological activities not related to bones including blood clotting, nerve conduction, muscle contraction, regulation of enzyme activity and cell membrane function Therapeutic Class: Minerals in bone formation, Specific mineral preparations Dosage & Administration Calcium Carbonate is always used orally and when used as an antacid the recommended doses for adults are equivalent to 540-2000 mg Calcium Carbonate 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 Calcium Carbonate (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 Calcium Carbonate per day and need to be adjusted according to the individual patient. To maximize effective phosphate binding in this context the Calcium Carbonate should be given with meals. Interaction Calcium Carbonate may enhance the cardiac effects of digoxin and other cardiac glycosides, if systemic hypercalcaemia occurs. Calcium Carbonate 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 Calcium Carbonate is used as the primary phosphate binder. Contraindications Hypersensitivity to the Calcium Carbonate 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 insufficiencies. Side Effects Orally administered Calcium Carbonate 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 are used widely in pregnancy by way of oral calcium supplementation. Calcium Carbonate can be used in lactating women too. Precautions In the presence of mild hypercalciuria, excretion levels must be carefully monitored and where necessary the dose of calcium carbonate 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. Use in Special Population 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 calcium carbonate 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. Storage Conditions Store in a cool, dry place in controlled room temperature.
