Pharmacology

Vitamin D3, in its active form (Calcitriol), works by binding to Vitamin D receptors (VDRs), which are found in various tissues throughout the body. Vitamin D3 has a half-life of around 50 days due to its fat-soluble nature. It is absorbed in the small intestine and binds to specific α-globulins before being transported to the liver. In the liver, it is converted to 25-hydroxy Vitamin D3 (Calcidiol), which is further hydroxylated in the kidneys to 1,25-dihydroxy Vitamin D3 (Calcitriol), the active form responsible for enhancing calcium absorption. Unmetabolized Vitamin D3 is stored in fat and muscle tissues and excreted in the feces and urine.

Administration of Osteo-D Max 2000 IU/ml Oral Solution

This medication can be taken with or without food.

Interactions

• There is an increased risk of hypercalcemia when taken with thiazide diuretics, calcium, or phosphate supplements.
• Antiepileptics (e.g., carbamazepine, phenobarbital, phenytoin, and primidone) may increase vitamin D requirements.
• Rifampicin and isoniazid may reduce vitamin D's effectiveness.
• Corticosteroids can counteract the effect of vitamin D.
• Caution should be used when taking digoxin or other cardiac glycosides.
• Reduced absorption of vitamin D can occur when taken with cholestyramine, colestipol, mineral oil, or orlistat.

Contraindications

Colecalciferol is contraindicated in conditions associated with hypercalcemia and in patients with known hypersensitivity to Colecalciferol or any of its components. It is also contraindicated in cases of vitamin D toxicity. 

Pregnancy & Lactation

Studies indicate that doses up to 4000 IU are safe during pregnancy. The recommended daily intake for pregnant women is 400 IU, but higher doses may be necessary in cases of deficiency. Vitamin D3 and its metabolites are excreted in breast milk. While no cases of overdose in infants due to maternal intake have been reported, practitioners should consider the total Vitamin D3 intake for both mother and child when prescribing.

Precautions

Caution is advised for people with high levels of calcium or phosphorus, heart problems, or kidney disease. Vitamin D should be taken with sufficient calcium and magnesium. When calcium levels are low, the parathyroid gland produces parathyroid hormone (PTH), which activates vitamin D and mobilizes calcium from bones to maintain vital functions, such as neutralizing body acidity. During lactation, vitamin D passes into breast milk, so it should be used with caution.

Storage Conditions

Store below 30º C, away from light and moisture. Keep out of reach of children.
