Calciferol 200000IU Injection

Pharmacology

• The active form of Vitamin D3 is Calcitriol, which binds to Vitamin D receptors (VDRs) in various tissues.
• Absorbed in the small intestine, Vitamin D3 is bound to specific a-globulins and transported to the liver where it is converted to 25-hydroxy Vitamin D3 (Calcidiol). Further hydroxylation occurs in the kidney to form 1,25-dihydroxy Vitamin D3 (Calcitriol), which is responsible for increasing calcium absorption.
• Elimination: Excreted via feces and urine, with non-metabolized Vitamin D3 stored in tissues like fat and muscle.
• Half-Life: Approximately 50 days, being fat-soluble.
