Pharmacology

Adequate Calcium in the blood is so vital to a wide variety of bodily functions that our internal biochemistry will not tolerate a deficiency even for short periods. Clinical evidence suggests that Calcium is useful for the prevention and treatment of Osteoporosis and associated fractures. Vitamin D is also essential for healthy bones as it aids in Calcium absorption from the GI tract. In addition to this it stimulates bone formation. Clinical studies also show that Calcium and vitamin D has synergistic effects on bone growth as well as in Osteoporosis and fracture prevention.

Dosage and Administration of Reef-D

One tablet in the morning and one tablet at night or as directed by the Physician

Dosage of Reef-D

One tablet once or twice daily with plenty of water or as directed by the physician. Taking in full stomach ensures better absorption.

Interaction of Reef-D

Oral Calcium can reduce the absorption of tetracycline and fluoride preparations and minimum 3 hours time should be allowed between ingestion of these medications. Thiazide diuretics reduces the renal excretion of Calcium. Phenytoin, barbiturates, glucocorticoids may induce metabolism of Vitamin D3. Concomitant ingestion of certain foods like spinach, cereals, milk and its derivatives may reduce the intestinal uptake of Calcium.

Contraindications

Hypersensitivity to any of the components, hypocalcaemia resulting from overdose of Vitamin D3, hyperparathyroidism, bone metastases, severe renal insufficiency, severe hypercalciuria, renal calculi etc.

Side Effects of Reef-D

Flatulence, diarrhoea, constipation, upper GI discomfort etc. are rare manifestation. Hypercalcaemia due to prolong use has rarely been reported.

Pregnancy and Lactation

Drug Classes

Specific mineral and vitamin combined preparations

Mode Of Action

This is a Calcium and Vitamin D3 preparation where Calcium Carbonate is sourced from coral origin. The Calcium Carbonate from Coral has a chemical structure that is very similar to the composition of human bone. Coral Calcium is similar to other sources but ensures better absorption. Vitamin D3 aids in the absorption of Calcium from GI tract and helps to maintain Calcium balance in the body.

Pregnancy

This can be given to pregnant and lactating mothers as per recommendation of physician.
