Osteo-D Max 2000 IU/ml

INDICATIONS

Vitamin D3 deficiency can occur in people whose exposure to sunlight is limited and in those whose diet is deficient in vitamin D3.

Cholecalciferol is essential for the effective calcium and phosphate absorption required for healthy bones and teeth, preventing rickets, osteomalacia and osteoporosis.
Cholecalciferol is also essential to prevent pre-eclampsia during pregnancy and breast feeding as it is an essential nutrient for a growing infant.
Cholecalciferol has vital role on immunity boost up.

PHARMACOLOGY

The active form of Vitamin D3, Calcitriol, exerts its effect by binding to the Vitamin D receptors (VDRs) which are widely distributed through many body tissues.Vitamin D3 has a half life of about 50 days as it is fat soluble.Vitamin D3 is absorbed in the small intestine and bound to specific a-globulins and transported to the liver where it is metabolised to 25-hydroxy Vitamin D3 (Calcidiol). A second hydroxylation to 1,25-dihydroxy Vitamin D3 (Calcitriol) occurs in the kidney. This metabolite is responsible for the vitamin's ability to increase the absorption of calcium. Non-metabolised Vitamin D3 is stored in tissues such as fat and muscle.Vitamin D3 is eliminated via faeces and urine.

INTERACTION

Drug interaction with medication: Concomitant treatment with phenytoin or barbiturates can decrease the effect of vitamin D because of metabolic activation. Concomitant use of glucocorticoids can decrease the effect of vitamin D. The effectsof digitalis and other cardiac glycosides may be accentuated with the oral administration of calcium combined with vitamin D. Strict medical supervision is needed and, if necessary monitoring of ECG and calcium. Simultaneous treatment with ion exchange resins such as cholestyramine or laxatives such as paraffin oil may reduce the gastrointestinal absorption of vitamin D. The cytotoxic agent actinomycin and imidazole antifungal agents interfere with vitamin D activity by inhibiting the conversion of 25-hydroxyvitamin D to 1, 25-dihydroxyvitamin D by the kidney enzyme, 25-hydroxyvitamin D-1-hydroxylase.

SIDE EFFECTS

Generally all nutritional supplements are considered to be safe and well tolerable. However, few most common side effects can generally occur including hypocalcaemia syndrome or calcium intoxication (depending on the severity and duration of hypocalcaemia), occasional acute symptoms include anorexia, headache, nausea, vomiting, abdominal pain or stomach ache and constipation with the administration of colecalciferol.

PREGNANCY & LACTATION

Studies have shown safe use of doses up to 4000 IU during pregnancy. The recommended daily intake for pregnant women is 400 IU, however, in women who are considered to be Vitamin D3 deficient a higher dose may be required. During pregnancy women should follow the advice of their medical practitioner as their requirements may vary depending on the severity of their disease and their response to treatmentVitamin D3 and its metabolites are excreted in breast milk. Overdose in infants induced by nursing mothers has not been observed; however, when prescribing additional vitamin D3 to a breast-fed child the practitioner should consider the dose of any additional vitamin D3 given to the mother.

PRECAUTIONS & WARNINGS

Plasma-calcium concentration should be monitored at intervals in patients receiving high doses of Vitamin D3, in renal impairment, and during pregnancy & lactation. People using Digoxin and Thiazide Diuretics should consult a health care practitioner before supplementing with Vitamin D3. People with liver or kidney disease, primary hyperthyroidism, lymphoma, tuberculosis and granulomatous disease should consult a health care practitioner before supplementing with Vitamin D3.
