Constipation, flatulence, nausea, abdominal pain and diarrhoea. Pruritus, rash and urticaria.

Drug Interactions

May affect the absorption of tetracycline when used together. Concurrent use with systemic corticosteroids may reduce calcium absorption. Thiazide diuretics may decrease urinary excretion of calcium. Concurrent use with ion-exchange resins may reduce GI absorption of vitamin D. Hypercalcaemia may increase the toxicity of cardiac glycosides during treatment with calcium and vitamin D, monitor ECG and serum calcium levels. Bisphosphonate or sodium fluoride should be given at least 3 hr before calcium-containing preparations.

Contraindications

Patients with hypercalcaemia and/or hypercalciuria. Nephrolithiasis, hypervitaminosis D, hypophosphataemia.

Mechanism of Action

Calcium carbonate is a calcium supplement that is used in deficiency states and as an adjunct in the prevention and treatment of osteoporosis. Vitamin D3 is a fat-soluble sterol, it aids in the regulation of calcium and phosphate homeostasis and bone mineralisation. Absorption: Calcium carbonate: About 15-25% gets absorbed in the GI tract. Converted to calcium chloride by gastric acid. Vitamin D: Well-absorbed in the GI tract in the presence of bile. Metabolism: Vitamin D: Undergoes hydroxylation in the liver and kidney to form the active metabolite, 1,25-dihydrocolecalciferol. Excretion: Vitamin D and metabolites are mainly excreted in the bile and faeces.

Special Precautions

Impaired calcium absorption in achlorhydria which is common in elderly. Increased risk of hypercalcaemia and hypercalciuria in hypoparathyroid patients receiving high doses of vitamin D. Caution when using in patients with history of kidney stones. Renal impairment; frequent monitoring of serum calcium and phosphorus is recommended.
