Hi-D3 800 Drops contain Calcitriol at a concentration of 800 IU per dose, a biologically active form of vitamin D3 essential for calcium homeostasis and bone metabolism. This medication is indicated for the prevention and treatment of vitamin D deficiency and insufficiency, particularly in patients at risk of osteomalacia, rickets, osteoporosis, or other metabolic bone diseases. Calcitriol facilitates intestinal absorption of calcium and phosphate, promoting bone mineralization and maintaining serum calcium levels within the normal range. Hi-D3 800 Drops are especially beneficial in individuals with impaired endogenous synthesis of vitamin D due to limited sun exposure, malabsorption syndromes, or chronic kidney disease. The oral liquid formulation allows for precise dosing and ease of administration, suitable for pediatric and adult patients. Dosage should be individualized based on serum calcium levels and clinical response, with caution exercised to avoid hypercalcemia and hypercalciuria. Regular monitoring of serum calcium and phosphate is recommended during therapy. Hi-D3 800 Drops should be used under medical supervision, particularly in patients with renal impairment or those receiving calcium supplements or other vitamin D analogs. This product offers a reliable and effective option for managing vitamin D deficiency and supporting skeletal health.
