• Rickets (in children, if prescribed appropriately)

• Osteoporosis (as adjunct therapy)

Mechanism of Action

Cholecalciferol (Vitamin D3) undergoes two-step activation:

1. Converted in the liver to 25-hydroxyvitamin D

2. Converted in the kidneys to active calcitriol

Its actions include:

• Increasing intestinal absorption of calcium and phosphorus

• Maintaining normal serum calcium levels

• Supporting bone mineralization

• Reducing elevated parathyroid hormone (PTH) levels

Adequate vitamin D is essential for maintaining strong bones and preventing bone-related disorders.
