Calcium Carbonate (625 mg), Alfacalcidol (0.25 mg)
calcium carbonate uses to reduces the deficiency of calcium in our body. calcium carbonate helps to make healthy bones, muscles, nervous system, and heart. it is also used as an antacid to relieve heartburn, aid in digestion and upset stomach. Alfacalcidol is used for the treatment of osteoporosis.
Mechanism of Action
Although alfacalcidol is widely used in the treatment of osteoporosis, its mechanism of action in bone has not been fully understood. Alfacalcidol stimulates intestinal calcium (CA) absorption, increases urinary CA excretion and serum CA levels, and suppresses parathyroid hormone (PTH) secretion.
Alfacalcidol is a precursor of active calcitriol. It does not require renal hydroxylation but requires 25-hydroxylation in the liver for conversion to calcitriol.
Adequately absorbed from the GI tract (oral).
Fat and muscle tissue; Enters into breast milk. Protein-binding: specific for α-globulin.
Hepatic; Rapidly converted to calcitriol.
Stool and urine (small amounts)
Thiazide may increase the risk of hypercalcemia. Certain antiepileptics such as carbamazepine, phenobarbital, phenytoin, primidone may increase the need for vitamin D. Rhimpsin, INH and corticosteroids may reduce the efficacy of vitamin D.
Inform the physician if the patient is allergic to the active ingredients and any other drugs. Brief about the allergy and the signs like:
• Shortness of breath
• Swelling of face, lips, tongue or throat or any other signs.
The patient should tell the doctor about any history of renal impairment.
Pregnancy, lactation, renal impairment, infants, elderly. Monitor serum levels of calcium in patients with renal failure. Caution in hypercalciuria esp in those with a history of renal calculi. Avoid in patients with hypersensitivity to injections containing propylene glycol
Calcium is found in breast milk. When calcium carbonate is used at recommended doses, it is unlikely to be harmful to the nursing child.
If a person takes calcium carbonate, can it increase their fertility (ability to become pregnant) or the possibility of birth defects? When men take calcium carbonate, there have been no studies looking at male fertility in pregnancy or potential problems for pregnancy.
