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 is absorbed in the small intestine and bound to specific-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 vitamins 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.

Indications

Rickets, osteomalacia and osteoporosis, preeclampsia, prediabetes.

Contraindications

Vitamin D3 is contraindicated in all diseases associated with hypercalcaemia. It is also contraindicated in patients with known hypersensitivity to Vitamin D3 or any of the components of the products. It is aslo contraindicated in severe renal impairment,

Hypervitaminosis D, Nephrotithiasis.

Warning & Precautions

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.

Side effects

Common side effects : Occasional acute symptoms include anorexia, lassitude, nausea & vomiting, diarrhea, constipation, weight loss, polyuria, sweating, headache, thirst, vertigo, and raised concentrations of calcium and phosphate in plasma and urine.

Rare side effects : Dry mouth, Headache, Weakness and lack of energy.

Use in Pregnancy & Lactation

Pregnancy: Vitamin D3 needs are increased during pregnancy. Vitamin D3 deficiency during pregnancy can affect bone development and immune function from birth through adulthood.

Low Vitamin D3 levels are common among those taking a standard prenatal multivitamin, which usually contains 400 IU, but is inadequate for pregnant women. Even 800 IU of

Vitamin D3 per day didn’t permit most pregnant women to reach a normal Vitamin D3 level. A recently completed study funded by the National Institutes of Health tested the safety and effectiveness of 4000 IU Vitamin D3 per day in pregnant women. The researchers reported that this dose was safe and effective in achieving normal Vitamin D3 levels and resulted in fewer pregnancy complications (infections, preterm labor, birth, and pre-eclampsia) when compared with 400 IU Vitamin D3 per day.

Lactation: It should be assumed that exogenous Vitamin D3 passes into the breast milk. In view of the potential for hypercalcaemia in the mother and for adverse reactions from Vitamin

D3 in nursing infants, mothers may breastfeed while taking Vitamin D3, provided that the

serum calcium levels of the mother and infant are monitored. The American Academy of Pediatrics (AAP) currently recommends that breastfeed infants receiving a supplement of

Vitamin D3 every day prevent Vitamin D3 deficiency and rickets.

Use in children & adolescents

There is no doubt that severe vitamin D deficiency leads to rickets in childhood and adolescence.

Drug Interactions

With medicine : Vitamin D3 interact with antacids (magnesium-containing), phenytoin, phenobarbital, cholestyramine, cholestipol, digoxin, thiazide diuretics. Many drugs cause

Vitamin D3 deficiencies because they interfere with the absorption and metabolism of

Vitamin D3 and includes cholestyramine, cholistipol, phenytoin, phenobarbital, orlistat, and mineral oil. Also, corticosteroids, such as prednisolone increase the need for Vitamin D3. Cholecalciferol is known to interact with Carbamazepine, Dactinomycin, Diuretics, Fosphenytoin, Miconazole, Phenobarbital, Phenytoin, Primidone. With food & others : Avoid alcohol or tobacco consumption while taking vitamin D3 because they can decrease its absorption.

Over dose

Symptoms: anorexia, vomiting, constipation, dystrophy, possibly fever with thirst, polyuria, apathy, hypercalcaemia . Storage Store below 300  C temperature and dry place, protected from light. Keep all medicines out of reach of children.
